All About Soils

All About Soils

The Cook County Extension office receives a lot of questions about soils and how to build up soils in an area where many of us have gravel or clay. Organics added to your soils are the key to changing the soil structure over time. You know you have pretty good soil when you can take a handful of the soil and squeeze it with your hand, when you open your hand it retains its form until you take your finger an gently poke it. If it breaks apart when you poke it you have pretty good soil tilth or structure.
If you have questions about how your soils work, the information below is based upon a great book, “Teaming with Microbes. The Organic Gardener’s Guide to the Soil Food Web.” It will help you understand much more how your soils work and what you need to grow great vegetables.

What are the characteristics of a healthy soil that will help your plants?

• Nutrient retention in your soil
• Improved soil structure (tilth)
• Improved disease defenses for your plants
• Influences soil pH for optimum plant growth
• Soil food webs are intact

How do we know if we have a healthy soil or not?
Most people start with a soil test.
When you do a soil test it usually tells you the percent of organic matter; pH (7 being neutral; acidic soils being below 7 and alkaline soils being above 7); amount of nitrogen, phosphorus and potassium (NPK).
What the soil test doesn’t give you is the soil texture; structure; whether you should garden organically or inorganically (what does that mean anyhow?), how to build up your soil to support a web system of local soil microbes, or how important the other macro and micro nutrients are to the success of your plants.

What does organic vs. inorganic mean when we are talking about soils/fertilizers?

• Inorganic or synthetic fertilizers: These are commercially prepared forms of nutrients. Nitrogen is obtained from the atmosphere and phosphorous and potassium are mined from the earth’s crust. They are generally concentrated. They don’t build the soil or support the microbial food web within the soil. A little bit of the nutrients are utilized at the root tip and the rest of the nutrients are often drained down through the soil until they hit the water table.

• Organic fertilizers: These fertilizers generally have a plant or animal origin. Animal manures or compost are some examples. Nutrients are contained generally in complex organic forms which will release more slowly over time. Nutrients are utilized by the microbes in the food web. They in turn release additional nutrients as waste materials and eventually die and decompose putting additional nutrients back into the soil.

In general, a garden should have about 8 percent organic matter in the soil or a little higher for vegetables.

Soil Texture:
This refers to the size of the mineral particles of the soil. Particles are sand, silt and clay. The relative proportions of those three make up your soil texture. “It takes 65 million clay particles to fill up the same amount of space as one grain of sand.” Ideal loam: 15% clay, 35% silt, and 40% sand, 5 – 10% organic matter.
These three particles are shaped differently and arrange themselves differently when grouped together:
~ loose & sandy
~ crumbly & light (loam)
~ compacted clay (particles are flat crystals that can pack together tightly leaving very little space for air)
You can’t really change the soil texture.

Soil Structure: (Tilth) This you can change. The soil structure refers to the way the mineral particles are arranged into aggregates (groups of particles loosely held together). The soil structure becomes a by-product of the decay of organic matter. You can change the structure of your soil with organic matter. The microbial life of the soil binds together the sand, silt & clay.

Organic matter – compost – humus – structure

Humus is the end product of organic decay. This decaying process usually takes place right under the ‘duff’ or layer of material you can recognize on the forest floor or the top of your garden. Humus is created by microbes. Humus is a fairly stable and complex carbon compound that serves to hold the pore structure of soil open. Little nooks and crannies in humus provide ‘condominiums for microbes’.

Pore space is a maze of minute continuous channels found throughout the upper layers of most soils. Very important for air and water flow. If there is inadequate pore space you may end up with air being utilized, no recharge of air occurs, and then you have anaerobic conditions that end up killing root systems.

Plant Roots: These act as places where ion exchanges take place. They are electrically charged with H+ cations. They give up these in exchange for anions like -NO3 (nitrate) or -SO4 (sulfate) or phosphate -(PO4). The cation exchange capacity of soils is based upon the amount of clay and organic matter it contains. Sand and silt have low exchange capacities.

pH: Every time a root tip exchanges a H+ (cation) it can be measured as pH or the concentration of H+ ions. The more H+ ions, the more acid the soil or solution. Root surfaces also take up negatively charged anions or hydroxyl (OH)- ions so that helps to balance out the exchange. pH influences the type of microorganisms that live in the soil. Certain fungi and bacteria are important to different plants to help them thrive.

Bacteria: They play a major role in plant nutrition. They lock up nutrients that might otherwise disappear due to leaching. They prefer cellulose over lignin. The bacteria remain on soil particles and that keeps the nutrients remaining in the soil. The bacteria in turn are eaten by protozoa and reduced to wastes. These nutrient wastes are picked up by the plant roots.
Bacterial slime raises soil pH; nitrogen-fixing bacteria generally require a pH above 7. Serve as barriers around roots to block entry of disease organisms.

Arachae: Discovered in the 1970s, these life forms are now considered to be the most abundant life form on earth. They are the most 
abundant ammonia oxidizers in soil – making nitrogen available to plants. They are decomposers of organic and inorganic materials. They produce methane – a key component of greenhouse gas. They are important members of the soil food web – much of what is still unknown.

Fungi: Fungi are unable to photosynthesize and have chitin in their cell walls instead of cellulose. They prefer lignin (woody materials). A teaspoon of good garden soil will have several yards of fungal hyphae. They can transfer nutrients from one end of the hyphae to the other. Phosphorus is especially made available to plants by fungi as they have the ability to release it from its chemical and physical bonds. Their hyphae leave microscopic tunnels in the soil that water and air can flow through. Fungi are the primary decay agents in the soil food web. The nitrogen released by fungi is the NH4 (ammonium form). Enzymes released by fungi are acidic and lower the pH.

Myccorrhizal fungi: There are two kinds: ectomycorrhizal fungi, grow close to the surface of roots and are associated with hardwoods and conifers. Endomycorrhizal fungi actually penetrate and grow inside roots and extend out into the soil. These are preferred by most vegetables, shrubs, perennials, annuals, etc. Some require specific plant hosts and become mutually dependent upon each other. Provide additional water and phosphorus to plants

Protozoa: They eat the bacteria, a few fungi and other protozoa. In turn, they provide food for nematodes and other worms.

Nematodes: (Non-segmented blind round worms) One teaspoon of good soil averages about 40 – 50 nematodes. Many of these nematodes made minerals or nutrients available to plants by releasing them from the protozoa or fungi they feed on. Nematodes need less nitrogen that protozoa so they release more nitrogen and make it available to the plants. Fungi and bacteria ‘hitch’ a ride on nematodes to different locations in the soil.

Arthropods: Arthopods have segmented limbs/bodies and an exoskeleton. Soil arthropods are important because they are shredders, predators and soil aerators. The presence or absence of some of these key arthropods can tell you about the health of your soils and the plants growing in them. Examples: springtails, mites, millipedes, ants, sow and pill bugs, etc.

Earthworms: Primary food source is bacteria although they will eat fungi, nematodes, protozoa and organic matter on or in which these microorganisms live. Worms can live for 15 years. They shred organic matter, aerate soil, aggregate soil particles and move organic matter and microorganisms in the soil. Vermicastings(worm poop) are 50% higher in organic matter than soil that has not moved through worms. Worms’ digestive enzymes unlock phosphate and other nutrients making them available for plants.
Bad news about earthworms: Forest floors that have been invaded by earthworms have completely altered the soil food web by drastically increasing the decaying of organic matter to point where it is not healthy for the trees and the rest of the soil food web. Earthworms are not native to the Great Lakes region. Their introduction has destroyed the ‘duff’ layer that dozens of understory plant species rely on to survive. Some of these native species cannot survive without that duff layer. Fungi, bacteria and other arthropods and even small animals are affected by disruption of the ecosystem that was developed without earthworms.

How do I know if I have a good soil food web present in my soil?

• If you have 5 – 30 earthworms in your garden soil in a square foot.
• Set a soil trap. Bury a quart-sized container in the soil so that the lip of the container is at the ground level. Put an umbrella over it or something to keep the rain out but keep it open at the soil level. Add a couple of moth balls. Leave alone for 3 – 7 days. Check to see what you have in your trap. If your soil is pretty good you will have centipedes, millipedes, other macroarthropods.

How can I use soil food webs to increase the health of my soil and the health of my plants?

Some plants prefer soils dominated by bacteria; other plants prefer soils dominated by fungi. They need nitrogen for building amino acids. Bacteria predominated soils have –NO3 (nitrate) predominately and are more alkaline. Fungi predominated soils have more –NH4 (ammonium) and are more acidic.

Fungal to Bacterial ratio (F:B)

1. Carrots, lettuce, broccoli, cole crops F:B ratio of .3-.8 to 1.0
2. Tomatoes, corn, wheat F:B ratio of .8 – 1 to 1.0
3. Lawns F:B ratio of .5 – 1 to 1.0
4. Conifer trees F:B ratio of 50 – 1000 to 1.0
5. Maples, oaks, poplars F:B ratio of 10 -100 to 1.0
6. Orchards F:B ratio of 10 – 50 to 1.0
7. Alder, beech, aspen, cottonwood F:B ratio of 5 – 100 to 1.0 (mature)
(Frankia bacteria fixes atmospheric nitrogen in alders)
8. Annuals: Prefer bacterially dominated soils
9. Perennials, shrubs: Prefer fungal dominated soils.

Add compost. Compost can inoculate an area with microbes to support soil food web organisms. Compost made with C:N ratio of 25 -30 to 1 is best. You can manipulate that ratio for vegetables to 25% alfalfa meal; 50% fresh grass clippings and 25% brown leaves or bark for more of a bacterial compost.

• Put down your compost first and then add mulch.
• Provide different kinds of mulch: leaves, grass clippings, wood chips, etc. for your trees, shrubs, perennials. These will provide different soil food webs.
• Rhizobia bacteria associated with legumes can be added to your beans, peas and will make nitrogen available in about two weeks after inoculation.
• A green mulch will provide bacteria to the soil; a brown mulch will add fungi to the soil. Peat moss used as mulch is sterile. Pine needles and cedar chips contain terpenes that can be toxic to many plants.
• Wetting your mulch grinding it up and working the mulch into the soil will support bacteria; coarser, drier mulch on top of the soil will support more fungi. Keeping your mulch on top of the soil larger (3/8” or larger) will prevent nitrogen being used up by bacteria. There will be enough nitrogen to feed the fungi.
• Keep your mulch layers 2- 3” to avoid blocking air and water resulting in possible anaerobic conditions.
• Active aerobic compost tea does work when brewed at room temperature. It takes about two days to make, use within 4 hours of completion. Do not use simple compost leachate or hanging a bag of manure in water. That results in anaerobic pathogens and possible alchohols.
• Rototilling and compaction of soils all have a negative effect on mycorrhizal fungi. Reducing this activity is key to keeping your soil food web healthy.
• Applications of synthetic fertilizers can kill microbes.
• If you add additional organic fertilizers, use low numbers.

The first step is to take a soil test. Call the extension office at 387-3015 to find out how to do this.


Cook County Extension office located in the CC Community Center building in Grand Marais does have soil testing available through the University. We do recommend a soil test before you start adding amendments to your soil. We also have an animal husbandry and gardening library available for folks who would like to check out more specific information on topics we discuss on Northern Gardening. Please call Diane at 218-387-3015 if you have questions or stop by.

Youth Spring Gardening Class

A youth spring gardening class will begin Tuesday, April 17 from 4 – 5 p.m. in the 4H log cabin building at the Cook County Community Center. The class will run every Tuesday through May 22. Youth can sign up for the After School Lounge in the I.S.D. #166 office and walk over with our youth coordinator, Melissa Wickwire, right after school, have a snack and be ready for gardening with Max Linehan and Penny Ortmann U of M Master Gardeners.

Container gardening workshop

Saturday, June 2, starting at 9 a.m. at the Cook County Community Center, our U of M
Master Gardeners will be hosting a container gardening workshop with topics that include: Growing Vegetables in Containers with Diane Booth; Spicing up Your Garden by Planting in Containers with Jane Horn; and hands-on container planting demonstrations with U of M Master Gardeners Nancy Carlson, Max Linehan, and Emma Bradley. Save the date!
Also, the Art Colony Potters will be making planters and garden art as a fundraiser for the ceramics studio. They will be sold during the workshop.
In conjunction with the Container Gardening workshop in June, the Cook County Master Gardeners will also be planning a container gardening contest this summer with prizes and a local garden tour on Saturday, August 18th. So if you are a gardener and would like to enter either your garden as an example of how people can grow in small spaces using containers or small raised beds, watch for more information about this in May and early June.

Cook County Co-op
If you’re planning to grow vegetables for the Cook County Co-op this summer, be sure to talk to Jeri Persons right away. The Co-op has new rules for local growers this year. Call Jeri at 387-2503.

Cook County Farm & Craft Market
The Cook County Farm & Craft Market will be making a table available for local growers who just have a small amount of produce to sell this year as well. Call Joan at 387-3101 to find out more.



Youth Gardening and Pruning Apple Trees

NorGard_030812.mp3110 MB
apple tree.gif3.51 KB

Welcome to Northern Gardening.

In this month's program, Karina Roth discusses the food program at Great Expectations School and how the school is using the greenhouse to grow food for lunches at the school.
She also has some requests for help from the community. Karina can be reached at 387-1876 if you can help.

  • The Food  Committee’s goal is to continue to have more locally produced food  for their lunch program at Great Expectations School. They have a greenhouse, but need help with adding more ventilation to it to use during warmer weather. This would allow more use of the greenhouse for growing warm season crops without over-baking.
  • Karina is also looking for people to help start tomatoes and peppers for the Great Expectations Plant Sale. Is anyone willing to help start them or take care of plants at your home? Call her at 387-1876.
  • GES could also use addditional indoor plant light stands, either be purchased or built, for more plant-starting options. Call Roth if interested.

Max Linehan, U of M master gardener, was in the studio to discuss the children’s gardening programs she does in conjunction with another U of master gardener, Penny Ortman. They are always looking for willing hands and help with their programs. These are the two upcoming sessions being offered.

  • Spring Session will be on Tuesdays, April 17 – May 22 from 4 – 5 p.m. at the 4H Log Cabin Building at the Cook County Community Center.  Youth in grades 3 – 8 grade are welcome to sign up for the After School Lounge program and walk over with them right after school. The program is free if your student participates in the After School Lounge program. If your child wishes to attend just the gardening program, the cost is $10 and parents need to be responsible for dropping child off and picking them up.
  • Summer Session will be on Tuesdays, June 12 – August 22. If your child is part of Summer KIDS Camp, then they will be automatically participating in this program. If you would like your child to just attend the Summer Gardening program the cost will be $15 for the summer to help pay for materials, etc.

If there is interest in having youth gardening programs either at Birch Grove Center in Tofte or up in Grand Portage, please contact Diane Booth in the Extension office at 387-3015.

Apple Tree Pruning Basics

Older trees that were planted years ago were on standard root stock so they grew quite large and were difficult to prune as they became older. Most apple trees being planted now are on semi-dwarf root stock or dwarf rootstock. These are less hardy than standard root stock, but reduce the size of the tree so that you can plant them closer together. To grow well you need to mulch, make sure they have good snow cover, and remove grass competition.

Regardless of the rootstock you choose, the training of the small tree will help determine the type of pruning you have to do on the mature tree later.

Correct training and pruning are important because they will affect time of production to some extent, sustained high yields, optimum fruit quality. You need strong branches that can hold a lot of fruit without breaking. And there has to be a balance between vegetative growth and growth that will produce fruit.

Pruning removes unproductive growth and encourages growth of new bearing wood so that at the end of each growing season, the top of the trees and the roots are in balance.

Dormant pruning removes some growing points, and this increases the root resources for the remaining buds.

Light exposure is very important for fruit production. The top of the tree will receive the most light. The middle of the tree will receive about 60 percent light and still be productive. If the lower, center part of the tree only receives 30% light, it will become less productive with smaller fruit and not good color.

  • Light exposure also depends upon the size of the tree. 
  • Open center trees that have a dense canopy at the top will shade more of the tree resulting in less production.
  • Pyramid-shaped trees exposes more leaf area to sunlight resulting in more productivity.
  •  Increased fruit production reduces the amount of tree vigor going elsewhere and helps control the tree, shoot growth and tree size.
  • Branches that are almost horizontal will reduce vegetative growth and more flower formation is stimulated. Branches that are bent below the horizontal will have more vigorous upright waterspouts near the base of the branch.

All pruning cuts can be classified as:

  • Heading back – removes only a portion of a branch resulting in usually vigorous growth. Cut directly above a bud. These cuts should best be done on 1-year growth rather than on older wood. Used on older wood induces waterspout growth. 
  • Thinning out – an entire branch is removed at the junction of the trunk or lateral branch. Doesn’t result in vigorous growth. Make sure you leave the branch collar.

So, if you are planning to purchase a new apple tree this year or if you have planted one a couple of years ago, here are some suggestions for working with your young apple trees. There should be an emphasis on training a young tree rather than pruning  it – you should very limited pruning on young trees.

The First Year

  • Pruning should be limited to cuts necessary for proper tree development and broken branches.
  • If you have a single whip (1 leader only) then you will need to head it back at about 30” – 36” to induce laterals to develop. All shoots developing below 18” should be removed.
  • Try to avoid heading back laterals.
  • Train a central leader for dominance to keep laterals in check. If the leader grows by more than 18” you may need to cut it back by ? because you want a strong leader.
  • Fruit forming on central leader needs to be removed to keep that dominance.
  • Use spreaders or weights to make sure the laterals have wide crotches for strength and better fruit bearing. Spreading the laterals will increase flower production and reduce vegetative growth. 60 degrees.

The Second Year

  • If you didn’t have laterals to spread the first year, make sure your laterals that grew last year that you are keeping are spread to 60 degrees. (easier after bud break)
  • Keep your central leader dominant. Remove any competing laterals.
  • Each lateral should be 8” from another lateral branch. They should not be clustered in the same area along the trunk of a tree.
  • Lower laterals on the tree should be longer to keep conical shape and allow more light. As the laterals develop, they may start growing vertically again and you will need to keep moving the crotch angle to 60 degrees.

Three to Five Years

  • Continue to make sure you keep your central leader dominant.
  • Keep your laterals in that conical shape.
  • Continue selecting specific laterals to keep and removing others at the main trunk.
  • You may end up doing more thinning cuts to remove unnecessary branches.
  • The key is to keep good light exposure and keep the tree from becoming vegetatively vigorous. You want the energy of the tree to go into fruit production.

Trees that are Bearing Fruit
Dormant pruning should be done in late winter before bud break. This time of the year reduces susceptibility of tree injury due to low temperatures.

  • Pruning trees after bud break or when in bloom can increase spread of diseases.
  • Branches growing upright into the interior of the tree can be thinned back to the lateral.
  • Branches growing down below a major lateral that are shaded can also be thinned back to the lateral.
  • Keep branches that are growing horizontally from the lateral.
  • purs are short 3- 5” branches that produce flowers and fruit on apple trees. Sometimes they become long, weak and heavily branched. You can thin them out and head them back to a strong bud.
  • Some spurs that are underneath a lateral branch can be removed to encourage more spur production where there is more light.
  • Remove water spouts and upright shoots.
  • Remove branches that are crossing and/or  dead or injured branches.
  • Once the height of the tree has been reached (8 – 10 ft dwarf) (12-16 ft semi-dwarf) you can cut the leader to a weak side branch. You will probably need to do this every year to keep it at that height. Laterals will all need to remain shorter than leader you will need to prune back into 2-year-old wood.

If you have older apple trees that have not been pruned for a number of years, here are some additional suggestions you may want to follow:

What do I do if I inherit older apple trees that have not been pruned?

  • First decide if you want to keep the tree or do you want to replace it with a new apple tree you can start training and pruning correctly? Do you like the fruit?
  • Does the tree receive all day sun?
  • Plan a 3 – 5 year recovery for this older tree.
  • Cut out all the dead wood.
  • If you find any diseased wood, cut that out next, making sure you disinfect your tools by wiping the blades with Lysol or ethanol or isopropyl alcohol. These are all better than bleach solutions. Burn all diseased or insect-infested wood.
  • You cannot remove more than 1/3 of the wood from the tree at a time and really should probably remove less.
  • Start by opening up the tree and removing branches that grow straight up.
  • Prune more heavily in the upper part of the tree first to get more light into the tree.
  • Cut out narrow crotched branches.
  • Cut out branches that are crossing each other.
  • Remove droopy branches – less fruit production or small fruit production.
  • Prune with a bud facing outward to force the new branch to grow in that direction.
  • If you have multiple leaders and no central leader, you may have to prune the best you can while keeping the open or vase shaped configuration.

If you have questions, call Diane Booth at 387-3015. Here is a link on pruning apple trees with diagrams included.

Beekeeping and How To Shrink Your Lawn & Plant Flowers Instead

NorGard_020812.mp3109.81 MB

Northern Gardening hosts Joan Farnam and Paula Sundet-Wolf welcome author Evelyn Hadden and bee entomologist Mike Goblirsch on the first show of the 2012 season.
Hadden has written a number of books about naturalistic landscaping, including "Apprentice to a Garden," and "Shrink Your Lawn: Design Ideas for Any Landscape." She has a new book coming out this month, "Beautiful No-Mow Yards." To see a video about this book, click here. In this program, she discusses what people can do to shrink their lawn and plant flowers and grasses which will thrive in our area.
Goblirsch is a Ph.D student in entomology at the University of Minnesota and will be teaching "Introduction to Hobby Beekeeping" at the Cook County Community Center on Saturday, Feb. 18 from 9 a.m. to 5 p.m. (To register for this class, call Diane Booth at 387-3015.)
In this program, he talks about the mysterious collapse of honey bee colonies across the world, as well as his experiences as a beekeeper.



Growing for the Co-op, growing for yourself

NorGard_011412.mp3112.58 MB

Northern Gardening hosts Diane Booth and Joan Farnam talk to Jeri Persons, produce manager at the Cook County Whole Foods Co-op, about what growers need to know about growing vegetables for the co-op. Rick Skoog, who grows kale, kohlrabi and radishes for the co-op, was in the studio as well.
The hosts also talk to Paul Gallione, from Johnny Seeds Co. in Maine, a popular seed source for Cook County gardeners.

Below are notes and questions used in the interview as well as lists of popular vegetable varieties that do well in Cook County.

Jeri Person, Cook County Co-op
Jeri: Many of us have watched the growth of the Cook County Whole Foods Cooperative over the years and have applauded the organic / local foods movement in part represented by the co-op. One of the goals both Extension and the Northwoods Food project share is trying to get more local food production in Cook County. How much of the produce provided by the co-op (%) is:

· From Cook County

· From the northeastern region of Minnesota

· From Minnesota

· From Wisconsin, Iowa or the Dakotas

· From further away?

· What about Canada?

As the produce manager for the co-op, would you please share some thoughts or ideas you might have for folks interested in selling produce to the co-op? How would they go about doing that and what things should they know about? Do you have written guidelines or certain requirements? (these are just some thoughts I have – you might have others)

· Reliable source: Can you meet with someone this time of year and contract for a certain amount of produce and kinds to be available – or is that too uncertain for our county?

What about if a group of growers worked together to create better certainty for products? Seasonal vs. out of season?

· Paperwork and tracking: How difficult is it to say, oh, I’ll purchase your extra apples but you will need to supply us with (x) amount in order to make it feasible for the paperwork and tracking we have to do for occasional suppliers?

An invoice that identifies the supplier or grower’s name and address. Good record keeping is important in case of a trace back of a product due to illness or injury.

· Organically certified vs. naturally grown:

Documentation needed for sale to Co-op? Three years of records, documentation that references the USDA organic certifying agent. If less than $5,000 products sold, a record of what has been done to produce and / or land where product has been grown?

· Quality of produce: Are you seeing any signs of insects, disease, bruising and damage, freshness, over ripeness or immaturity? Is the product kept cold after picking, how soon before the product is brought to the Co-op before being sold? What condition does it need to be in? Dirt washed off, bundled in the case of radishes, carrots, small onions, small turnips, lettuce cleaned and spun dry???

· Contamination of product: Is the product transported in clean boxes, containers, or with dogs, dog hair and dog breath? Are there signs of contamination by rodents, insects or birds? Does the grower wash his / her hands before picking produce?

· Is the produce something people will buy? If wild raspberries are abundant and some is picking them and trying to sell them, will people buy them if they are readily available? If you are growing a more unusual product like purple mizuna – it might be easy to grow – but will people purchase it? Are you willing to try things like this?

Licensing, state requirements, etc… · Commercial food operators(i.e. restaurants, caterers, grocery stores, food markets) can purchase produce directly from the grower if the person is selling produce that they have grown on their own land.

*State of Minnesota Constitution, Article 13, Section 7 NO LICENSE REQUIRED TO PEDDLE. Any person may sell or peddle the products of the farm or garden occupied and cultivated by him without obtaining a license therefor.

*Minnesota Statutes, Chapter 28A.15, Subdivision 1 highlights:

Sales by farmers, not others in food business

Prepares and sells not potentially hazardous food at community event / farmers market $5000 or less. “Products are homemade and not subject to state inspection” if they are prepared in a non-licensed kitchen. Name and address of person preparing and selling the food.

Home processed / home canned foods need to have less than $5,000 in gross sales and can be pickles, vegetables or fruits having a pH value of 4.6 or lower.

· If a grower is selling produce to commercial food establishments, is the grower considered an approved source?

*Yes, as long as the food is not processed and is grown on the farm or garden cultivated by them. Food cannot be prepared or stored in the private home.

· Would a grower be required to have a license for foods that are processed?

*Yes, but processing does not include trimming as part of the harvest process or preliminary washing to remove extraneous soil and debris. Cutting, heating, canning, freezing, drying, mixing, coating, bottling would require a license.

· What if I buy produce from my Uncle Sam and want to resell it here along with my produce?

*You might need to be licensed as a Minnesota Wholesale Produce dealer.

· If a grower does not need a license, does that mean they do not have to comply with good agricultural and management practices?

*No, even though a grower

Jeri: What products are you looking to maybe purchase locally?

Meeting in April with potential growers for the Whole Foods Coop?

Johnny's Seeds, Paul Gallione
Paul: As a small commercial grower in Maine, do you have any additional suggestions we have not discussed for marketing your produce to a Whole Foods Cooperative or restaurant, etc?

Paul, you operate a small organic farm in Maine, you are an agonomist and you work as a technical services technician for Johnny’s Seeds. Tell us more about what you grow and what you do for Johnny’s.

Johnny’s Seeds has become known for selling seeds that will do well in short season, cold weather varieties. Winslow, Maine where Johnny’s Seeds is located sits at a latitude of 44.54 while Grand Marais is about 47.73. Our growing zones would be considered zones 3 and 4. How different or similar is your growing zone to ours?

· Have you noticed a change in climate that has been translated to being able to grow longer days to maturity for vegetable varieties?

We have seen a resurgence in both gardening as a whole and especially in gardeners looking for heirloom or open-pollinated varieties. Johnny’s offers some heirloom varieties but still offers a large number of F1 hybrids. Do you see this changing in the near future? Is Johnny’s doing more research on heirloom varieties for northern climates?

Johnny’s offers some seed varieties they have developed themselves. Talk to us a little bit about the process you go through to develop those varieties.

Landscaping or Lakescaping for Wildlife, or Not?

Welcome to Northern Gardening!

Hosts Joan Farnam and Diane Booth talk about  "Landscaping for Wildlife, or Not?" with Carroll Henderson, DNR Non-game Wildlife program leader and Molly Hoffman, well-known local gardener and birder. Northern Gardening airs on the second Thursday of every month from 4 – 5 p.m. and is hosted by The Northwoods Foods Project and Cook County Extension. It is also rebroadcast at 6:00 a.m. on the 2nd Saturday morning of the month

Carroll has been the DNR Non-game Wildlife Program leader since the DNR program started in 1977. Here are some of the topics discussed in the program:

• Do we have bluebirds here in Cook County? What can people do to support them? They require a 5/acre home range per pair

• What about trumpeter swans? Weren’t they originally found around the Great Lakes?

• Pileated woodpecker? 100 acres for home range pair

• Yellow bellied sapsuckers? 10 acres home range pair

• Hairy woodpecker? 25 acres home range pair

• Downy woodpecker 10 acres home range pair

• Deer mouse 3- 4 acres home range pair

• Red squirrel 100 acres home range pair

People often move to northeastern Minnesota to "get back to nature." Gardening is one of those activities. Many of us are interested in growing our own food and still want to live harmoniously with the local animals that live here as well. It is kind of a balancing act.I know Molly, you and Ken have really strived to achieve that balance on your property.
Molly and Carroll: Can you give us some suggestions about how to enhance our properties for wildlife use?

• Animals need food, water, shelter and space.

• Having a diverse landscape is important as it supports more species of wildlife

• Your landscape is less vulnerable to large scale destruction caused by insect pests or diseases that can devastate a single species

• You increase the ecological stability of your yard by increasing the number of plant species

• By planting certain plant species on your property, you can increase wildlife abundance.

Carroll, in your book, "Landscaping for Wildlife" you have appendixes for plant groups that also include plant characteristics, height & width, sun exposure, moisture preference, pH preference, soil types and then what their value is for wildlife and how you can use them in your landscape.
Number of wildlife species is also documented for

** What about our native hawthorns here?

Bats and birds can be especially effective helpmates in the landscape and in the garden. Molly and Carroll can you give us our listeners some ideas about what species we might want to encourage and how we might do that?

1. Pollination with insects and birds

Hummingbirds for pollination:

• Delphinium, bee balm, bleeding heart, canna lily, dahlia, 4-o’clock, fuschia, impatiens, sweet William, honeysuckle, morning glory, apple, crabapple, hawthorn, azaleas

• Jewelweed (Impatiens

• Scarlet runner beans

• Coralberry

• Love misters for water

• Need cover and perching places close to the humming bird feeders / flowers

• Solution ¼ sugar water – very clean – no red dye

Wings at 55 beats per minute

Fatten up in August / early September

Need to nearly double their weight in fat stores for migration

Butterflies for pollination:

• Creating puddling places

• Creating hiding places for butterflies by intermingling various heights of plants and evergreens

• Creating a long season of nectar sources from early spring to fall for larva and adults

• Herbicide & pesticide free area

• Basking areas – large flat rocks to warm up on

• Butterfly houses?? Have you talked to anyone where these are being used? What butterflies

might overwinter in them?

Moths: Sweet William, 4-o’ clocks, heliotrope, nicotiana, petunias

Specific larval plants for specific butterfly and moth larvae (coevolution & pollination)

• i.e. Baltimore Checkerspot larvae and turtleheads or chelone

2. Bats and insect control ‘Woodworking for Wildlife’ book by Carroll Hendersen

• Provide the right habitat to encourage insect-eating predators like purple martins, dragonflies, tree swallows, bluebirds.

• How well do bat houses work? Our house is wrapped with tyvek – they love that.

• Bats can eat 3,000 – 7,000 insects / night

• What are the favorite insects they consume?

If you are lucky enough to live along a lakeshore, you want to seriously consider "lakescaping" along the shore to increase the wildlife using the area. Carroll’s book, ‘"Lakescaping for Wildlife and Water Quality’ would be a great resource.
In Cook County, we have folks who live along Lake Superior and folks who live on inland lakes… can you make some suggestions for what folks might want to consider when they purchase lake property?

• Live and dead plants for habitat along the shore – they absorb the energy of waves to prevent soil erosion

• Dead trees and logs

• A thriving plant and animal community will give you better water quality

• How do people get started if they have lawn right down to the shoreline?

• Buffer zone – take a look at the native landscape around your lake and learn what native plants thrive there

• Mulching native plantings / keeping everything weeded well to get established

• Leave dried vegetation in the winter for interest and cover for wildlife

• Shoreline stabilization - great section in your book on bioengineering- wattles, soil erosion blankets, brush mattresses, – also local Soil & Water office can be a great resource

1. Suggestions for plant species for bioengineering

• Speckled alder

• Red osier dogwood

• Willows

• American elderberry

• Arrowwood

• Nannyberry

2. Great information on plants that grow along buffer zones showing what wildlife uses them, sun exposure, habitat, seasonal interest, etc.

The most numerous calls I receive during the gardening season (besides what vegetable varieties to plant and what is wrong with my plant) - has to do with deer, bunny, vole and chipmunk control. The last couple of years this has gone on to now include problems with crows, racoons and groundhogs. So, let’s spend a little bit of time talking about these critters and humane methods to co-exist without losing your entire vegetable crop, flowers or fruit trees…

• Fencing – exclusion, type of fencing, baiting if using electrical. Groundhogs? Deer, hare and voles (winter control)

• Live trap and relocation?

• Plantskydd or liquid fence

• Homemade repellent of 4 eggs, 2 ounces of red pepper sauce, 2 ounces of chopped garlic – put in 1 quart container and add enough water to fill. Blend, strain, and add antiperspirants for longer lasting…(could burn your plants) All of these work about equally well or not as the commercial varieties.. ‘the Truth about Garden Remedies w/ Jeff Gillman’. They last a short time. None work in the winter or really very well under heavy deer pressure

• Hanging bars of soap will protect things around a meter in diameter. Research shows it doesn’t matter what brand of soap you use

• Timing of when you grow things?

• Creating a false food environment that will support more animals within a smaller space


Great Expectations School will be having a Pancake Breakfast and Plant Sale on Saturday, May 21. Plant sale goes from 8:00 a.m. until 1:00 p.m. with the pancake breakfast from 8:00 a.m. until 11:00 a.m.

All proceeds will go to support the school!

Tom Plocher will be here for a second Grape Workshop on Saturday, May 21st from 1- 3 p.m. at the Cook County Community Center. Grape varieties are being trialed here by a number of gardeners so come and learn more about growing grapes in our northern climate.

The Small Footprint Living Fair emphasizing sustainable living will be held this year all day on Friday, June 24 and Saturday, June 25. 18 classes will be held in the areas of animal husbandry, green building, energy, and growing. A silent auction will be held where a greenhouse built on Friday and a large water cachement system built on Saturday will go to the highest bidder. Noon time speakers on bioenergy / biomass and community organizing for sustainability will be wonderful to listen to while you ‘chow down’ on homemade soups and build your own sandwiches. An environmental film festival will be held on Friday evening from 4:30 until 9:00 p.m.

Brochures are available around town, at the Cook County Extension office, and on the web at Call 218-387-3015 and I will be happy to mail one out to you or e-mail you a copy.

Organic Production, Mulches & Tomato Varieties for the North Shore

NorGard_Thurs_041411.mp3102.27 MB

Organic Food Production, Mulches, Pruning and Tomato Varieties
April 14, 2011

Welcome to Northern Gardening!

In this show, Joan Farnam and Diane Booth talk about Organic Food Production, Mulches, Pruning and Tomato Varieties. Guests are  Jim Riddle from the University of Minnesota Organic Ecology Research and Outreach Program in Lamberton and local gardener Bill Lane.

What is organic production?
There are lots of terms out there like ‘natural’, ‘sustainable’, ‘green’ or ‘locally‐grown’, but what does the term "Organic" mean?
• Organic production is defined by the USDA National Organic Program regulation as a “production system that is managed…to respond to site‐specific conditions by integrating cultural, biological, and mechanical practices that foster cycling of resources, promote ecological balance, and conserve biodiversity.”

Crop Farms
‐ 3 years with no application of synthetic fertilizers, pesticides or Genetically Modified Organisms (GMOs) prior to the first harvest of organic crops
‐ Buffer zones to prevent contamination from adjoining land uses
‐ Organic system plan for the farm
‐ Use of natural inputs or approved synthetic substances on the National List only after preventative practices are insufficient
‐ No use of GMOs, sewage sludge, ionizing radiation
‐ Use of organic seeds and planting stock
‐ Raw manure and compost must follow restrictions to safeguard human and environmental health
‐ Maintain or improve physical, chemical and biological condition of the soil, minimize soil erosion, use crop rotations
‐ No field burning to dispose of crop residues – burning only to suppress disease or stimulate seed germination – flame weeding allowed.

Processing Operations
‐ Mechanical or biological processing methods
‐ No commingling or contamination of organic products
‐ No use of GMOs, ionizing radiation, artificial dyes, solvents or preservatives
‐ Use proactive sanitation and facility pest management practices to prevent pest infestations
‐ No use of fungicides, preservatives or fumigants in packaging materials
‐ 100 percent organic ingredients; 95 percent organic ingredients or 70 percent organic ingredients
‐ Required traceability – name of certification agency on product’s information panel

Livestock Operations
‐ 100 percent organic feed for all organic animals
‐ Organic management for last 1/3 gestation for meat animals and 2nd day after hatching for poultry
‐ One year of organic management for dairy cows
‐ Mandatory grazing on pasture for ruminants at least 120 days per year
‐ Mandatory outdoor access for all species when weather is suitable
‐ No antibiotics, growth hormones, GMOs, or feeding of animal by‐products
‐ Manure needs to be managed to prevent contamination of crops, water and to optimize recycling of nutrients.

Food labels review:
• "Natural" is simply a ploy to get you to buy a product. Doesn’t let us know whether it is organic, local or humanely raised.
• "No Hormones" is false because all animals have hormones in their products.
• “Naturally raised” is a voluntary (read: unregulated) label that means livestock have been raised without antibiotics and growth hormones and have not been fed animal byproducts.
• Cage-Free: Hens are uncaged inside barns or warehouses but may not have access to the outdoors.
• Free-Range: Essentially the same as “cage‐free”, hens are uncaged and more likely to have access to the outdoors.

Why should I care if I grow my own foods organically or purchase organically grown foods?

 Health Reasons
1. Exposure to pesticides is associated with the risk of cancer.
2. Organic products have very low or no pesticide residues.
3. Organic product consumption reduces exposures to organophosphorous insecticides that are known to disrupt neurological development in infants and children.
4. Vegetables grown on organic farms or non‐organic farms have the same amount of risk for sources of food borne disease.
• Nutrition
1. Organic crops contain fewer nitrates, nitrites and pesticide residues.
2. Organic crops contain more dry matter, vitamin C, phenolic compounds, essential amino acids, minerals and total sugars
• Soil Quality
1. Organic practices build soil organic matter content – offsets tillage, increases microbial activity.
2. By year 4 or 5 of organic production, often will out produce conventional farming methods.

1. Diverse plant communities support beneficial insect communities that help manage pest populations.
• No Genetic Engineering
1. Genetically engineered Bt corn harms aquatic insects and disrupts stream ecosystems.
2. Genetically engineered crops have established feral populations outside of cultivated crops.

Climate Change
1. Integrates closed nutrient cycles and enhances soil carbon sequestration
2. 33 percent reduction in fossil fuel use for organic corn/soybean farm systems that use cover crops or compost instead of chemical fertilizers

Feeding the World
1. 30 percent increase in world‐wide yields using organic methods.

Mulches and Soil Amendments

What’s the difference between a soil amendment and a mulch?
• Mulches are placed on top of the soil.
• Soil amendments are incorporated into the soil.

What’s the purpose of a mulch or a soil amendment?
• A soil amendment is any material added to a soil to improve its physical properties, such as water retention, permeability, water infiltration, drainage, aeration and structure. The goal is to provide a better environment for roots.
• A mulch is left on the soil surface. Its purpose is to reduce evaporation and runoff, inhibit weed growth, and create an attractive appearance. Mulches also moderate soil temperature, helping to warm soils in the spring and cool them in the summer. Mulches may be incorporated into the soil as amendments after they have decomposed to the point that they no longer serve their purpose.

Soil Amendments
 There are two broad categories of soil amendments: organic and inorganic.
• Organic amendments come from something that is or was alive. Organic amendments include sphagnum peat, wood chips, grass clippings, straw, compost, manure, biosolids, sawdust and wood ash.

Organic amendments increase soil organic matter content and offer many benefits. Organic matter improves soil aeration, water infiltration, and both water- and nutrient-holding capacity. Many organic amendments contain plant nutrients and act as organic fertilizers. Organic matter also is an important energy source for bacteria, fungi and earthworms that live in the soil.

The Changing Forms of Soil Organic Matter
• Additions. When roots and leaves die, they become part of the soil organic matter.
• Transformations. Soil organisms continually change organic compounds from one form to another. They consume plant residue and other organic matter, and then create by-products, wastes, and cell tissue.
• Microbes feed plants. Some of the wastes released by soil organisms are nutrients that can be used by plants. Organisms release other compounds that affect plant growth.
• Stabilization of organic matter. Eventually, soil organic compounds become stabilized and resistant to further changes.

Inorganic amendments, on the other hand, are either mined or man-made. Inorganic amendments include vermiculite, perlite, tire chunks, pea gravel and sand.

Mulches: Organic and Inorganic
• Reduce weed growth
• Regulate temperatures
• Maintain uniform moisture
• Organic mulches can add nutrients and humus

Organic: straw, cardboard, wood chips, pine needles, grass clippings, leaves, compost,
Inorganic: black plastic, clear plastic, newspaper, red plastic,
Cover crops / green manures: clover, rye, buckwheat, legumes, etc.

Tomato Varieties
• Determinate vs. indeterminate
• Use for the tomato or fruit characteristics
• Disease resistance
• Heirloom or open-pollinated or hybrid
• Time to maturity

Sun Gold is a 65-day, hybrid, indeterminate golden-orange cherry tomato. The plants are big and rangy, so they need to be well staked, and should be surrounded by a strong cage. Support them well, and they'll produce an incredible abundance of 1" diameter ultra-sweet fruit over a full 3 months. If you live where summers are hot, you probably don't have much trouble growing sweet, flavorful tomatoes. But in areas where summer is short and nights are cool, tomatoes never get very sweet. I have been so spoiled by Sun
Gold's dependable super-sweet flavor that I now add them to my tomato sauces and slice them onto my sandwiches.

Juliet is a 60-day indeterminate that produces a huge crop. The fruit is oval and it's about 2" long. It's firm, glossy and quite dense, like a miniature paste tomato. Juliet ripens fast and furious, and I use it for soups, sauces, salsas and cold salads. They also get stewed whole for canning, and get halved for drying. Leave on the vine a long time for the best flavor as it turns color fast but isn’t ready.

Sweet Million--Indet. Hybrid. (65 days) An improved Sweet 100 type cherry. Equally prolific and sweet, but with less cracking and better disease resistance.

Early Girl--Indet. Hybrid. (64 days) Very early, red salad tomato. Consistently does well in taste tests. Bush early girl that is determinate. BURPEE or Early Girl Improved (60 days) Ind. PINE TREE

Glacier – OP (56 days) Det. Superior in flavor to Siberia, Stupice and Bloody Butcher. I haven’t tried this one yet, but plan to compare it to some of the others in this early class. One to try from FEDCO

Black Prince – OP (75 days) Ind. Outstanding flavor similar to Black Krim but a bit earlier, more uniform and without a tendency to crack.

Honeydrop – OP (62 days) cherry tomato that is very sweet, juicy, fruity. Light honey gold in color. One to try from FEDCO.

Gardener’s Delight – OP (68 days) Ind. Large cherry tomato that has a tendency to crack but has excellent flavor.

Sweet Chelsea – hybrid (67 days) Large cherry tomato that is indeterminate but bears lots of great tasting fruit perfect for salads.

Grandma Mary’s Paste Tomato – (68 days) OP Ind. Tried for one year – will try again – was too late even though it is supposed to be early. FEDCO

Fourth of July – hybrid (49 days) Ind. Haven’t tried this one yet, but will be trialing this one in the summer. It has been grown in St. Louis County with good results. BURPEE

Sweet Baby Girl - hybrid (65 days) Ind. Great tasting, very prolific cherry tomato that grows in immense red clusters.

Anna Russian - OP (65 days) Ind. Teardrop shaped fruit very large – up to a lb – too sweet and mushy for me. More of a dark pink color.

Prune for plant health
1. Dead or dying branches
2. Branches that rub together
3. Mechanical damage

Prune to maintain your plants
1. Encourage fruit and flowers
2. Maintain a dense hedge
3. Keep a tree form or shape

Prune for plant appearance
1. Control the plant size
2. Keep everything well proportioned
3. Remove branches, suckers, waterspouts

Prune to protect property
1. Narrow crotches w/ included bark
2. Plant obscuring vision
3. Hazardous trees

When to prune
Early Spring Bloomers - Prune after blooming before flower buds are set for the following year.
Foliage Shrubs - Prune early in the year before the leaves bud out
New Growth Bloomers - Prune in the spring
Hedges – Prune twice a year – spring and fall – keep base wider than top for sunlight
Older, Overgrown Shrubs – Renewal pruning 1/3 over three years
Spruce / Balsam Fir - Early spring – side buds will grow if terminal bud is removed
Pines – Young candles can be cut back up to 2/3 – if you remove terminal buds there are no lateral buds
Arborvitae, junipers, yews, hemlocks – They can be cut back anytime through middle of summer

Sowing Seeds in Winter

NorGard_031011.mp3106.93 MB

Sowing seeds in the wintertime sounds like a pretty crazy idea, but Northern Gardening hosts Diane Booth and Joan Farnam talk about this amazing trick with  Sue Schiess, U of M Master Gardener from Hennepin Count on this week's program. Later in the show, Jerry Starr and Peter Henrikson  discuss how they designed and built a solar greenhouse at Great Expectations School which has provided students with salad greens this year.

Note: if you want to learn more and/or want to start a vegetable garden this year, there will be a 2-hour workshop on how to start a vegetable garden at the Cook County Community Center from 1o a.m. to noon on Saturday, March, 26. Everyone is invited. For more information, call Diane at 387-301.

Winter Seed Sowing is a really old method of starting seeds during the winter time without starting your seeds or plants indoors under grow lights.

What  is Winter Seed Sowing?

  • An easy seed germination method that allows you to plant seeds in milk jugs or other containers, set them outside, and let ‘Mother Nature’ start these seeds when the timing is right for those particular seeds.
  • The temperature differences with freezing and thawing helps loosen up the seed coats and allows for germination at the correct time.

What kind of seeds would you use?

  •  Seeds that typically reseed themselves or self sow
  • Wildflowers / native seeds
  • Seeds that are considered to be hardy
  •  Seeds that can be directly sown early
  • Seedlings can withstand frost
  • Seeds that can be sown outdoors in Autumn, early Winter, early spring while nights are still cool
  •  Seeds that can be sown in early Spring while frosts may still occur, like spinach and lettuce.
  • Seeds that need to be pre-chilled, stratified, etc. to break their dormancy

How do you do it?

  • Save clear milk jugs, take out containers, strawberry containers – anything that can be used as a miniature greenhouse.
  • Make sure your containers are clean before using them.
  • You will need holes poked in the bottom for drainage and holes poked in the top for air circulation and for heat escape during warmer days.
  • Cut the milk jug nearly all the way around about 1/3 to 2/3rd of the way up on the jug.
  • Leave the handle part attached and bend it backwards.
  • Put about 3 inches of fairly good soil with some fertilizer in the bottom. Add another inch of germination mix to the soil for where your seeds will begin germination.
  • Make sure that the soil you add is already pre-moistened.
  • Plant your seeds to the correct depth.
  • Make sure you label your container with duck tape label on the bottom and /or a plastic label wrapped in tinfoil and placed inside the container. The tinfoil prevents the ink from breaking down. You can use a paint pen on a wooden stick as well.
  • Duck tape the milk jug back together.
  • Stick your containers outside where you can easily get to them.
  • Keep the cap on until the weather warms up.
  • Once the seedlings have their first set of true leaves, you can gradually open the top of the milk jug or cut more holes in the jug and expose them to more wind variations.
  • Eventually you transplant them into the garden or into larger pots and place them outside, protecting them at night if need be, until you can transplant them into the garden.

Why would people want to do this?

  • It allows you to start a lot of seeds very cheaply without having to purchase or make an indoor light setup.
  • If you have limited space in your home, this allows you to start a lot of seeds ahead of time outdoors.
  •  Gives you gardening projects to do during the off-season.
  • Recycle and reuse milk jugs, take out containers, anything you can turn into a miniature greenhouse, basically.
  •  Damping off is less likely to occur using this method. (Damping off is when young seedlings wither and seem to die at the soil line. It is usually caused by two fungi Rhizoctonia solani and Pythium species.
  • Rhyizoctonia usually causes stem lesions that girdle the stem. Pythium attacks underground root hairs and root tips either causing the seed to rot in the ground or to wither and die. Other fungi can also be associated with this like Botrytis cinerea, Sclerotina sclerotiorum, Alternaria species, Phytophthora
  • species, Fusarium species, etc.)
  • Stronger, hardier plants often result.
  •  Hardening off your plants is much easier. They are already used to temperature and light fluctuations and really only need the addition of being hardened off to wind.

Solar Greenhouses

What is a solar greenhouse and what makes it different than a regular greenhouse? All greenhouses collect solar energy, but solar greenhouses are designed to collect solar energy during sunny days and store the heat for use at night or during periods when it is cloudy.

A lot of people are getting more excited about the use of solar greenhouses. This is not a new concept. It was used during the time of the Romans and in this country was readily discussed in the 1970’s and 1980’s.
The Romans improved on Greek solar architecture by covering south-facing windows with clear materials such as mica or glass. They also passed sun-right laws that forbade other builders from blocking a solar-designed structure's access to the winter sun.
The ancient Romans not only used window coverings to hold in solar heat for their homes but also relied on solar heat traps for horticulture so that plants would mature quicker, produce fruits and vegetables out of season, and allow for the cultivation at home of exotic plants from hotter climates. With the fall of the Roman Empire, so to came the collapse of glass for either buildings or greenhouses.

Basic Principles of Solar Greenhouse Design (Passive and Active)
• They have glazing materials oriented to receive maximum solar heat during the winter.
• Use heat storing materials to retain solar heat.
• Have large amounts of insulation where there is little or no direct sunlight.
• Use glazing materials and glazing installation methods that minimize heat loss.
• Rely primarily on natural ventilation for summer cooling.
• Should be twice as long as it is wide to offset the effect of shade from the east and west walls.
• The peak should be made about as high as the building is wide.
How has the Great Expectations school greenhouse been designed and built using those principles?
• Shed type solar greenhouse with orientation of the long axis running east to west.
• South facing wall is glazed to collect the optimum amount of solar energy.
• North facing wall is insulated to prevent heat loss. R-22 for roof and walls
• North wall is covered with reflective material to reduce the effects of poor light distribution in an east-
west oriented greenhouse.
• 45 degree south roof glazing? (site latitude 47 + 10-15 = 57 -62 degrees)
• What type of glazing material was used?
• Part of end walls glazed for additional light.
• Earth thermal storage (ETS) collection of solar heat beneath the floor with pipes and rock flooring 3 times the volume of rocks for heat storage than water storage due to their lower value for heat storage
• Active solar was used where 4” black corrugated sewer pipe is in a bed of ? - 1 ?” rocks under the greenhouse. (Divide the square feet of the greenhouse by 2 to get the number of feet of 4” pipe you will need.) Pipes go up at each end of the greenhouse where small fans force the warm, heated air at the top of the greenhouse down into the pipes, heating up the floor area of the greenhouse. This heat then is
given off when the temperatures of the greenhouse decline such as in the evening. Is one pipe higher
than the other, giving a circular flow?
• Sand covered polyethylene sheet over the top of the rocks to prevent an air gap if the rocks settle.

How to select glazing materials?
• Lifespan
• Resistance to damage from hail or rocks
• Ability to support your snowload
• Resistance to condensation
• Sheet size and distance required between supports
• Fire-resistance
• Ease of installation

Glazing materials have a National Fenestration Rating Council Sticker that lists the following factors:
1. The SHGC (Solar Heat Gain Coefficient) is a measure of the amount of sunlight that passes through a
glazing material. A number of 0.60 or higher is desired.
2. The U-Factor is a measure of heat that is lost to the outside through a glazing material. A number of
0.35 BTU/hr –ft2-F or less is desired.
3. VT or visible transmittance refers to the amount of visible light that enters through a glazing material. A
number of 0.70 or greater is desired.
4. PAR or photosynthetically active radiation is the amount of sunlight in the wavelengths critical for
photosynthesis and healthy plant growth. PAR wavelength range is 400 – 700 namometers.

Active Solar Storage

Year round growing – 5 gallons of water storage per square foot of glazing.
Season extension – 3 gallons of water storage per square foot of glazing
Small sized containers like glass bottles provide more heat storage than large 55 gallon drums.

Grow a Flower Garden This Year

Northern Gardening_6A_SAT_021211mp3.mp3108.61 MB

Northern Gardening with hosts Emma Bradley and Joan Farnam talk to Tom Kasper, Duluth maintenance supervisor and co-host of WDSE's "Great Gardening" show and Paula Sundet Wolf, a former host of Northern Gardening and an exceptional gardener, about growing flowers on the North Shore. Pictured, at left, is a pot of alyssum and lettuce.

Here are some tips on how to begin a flower garden this spring:

• Sketch out your plans for your garden. Make a diagram of the area, including its width and length. This will help you properly place the plants as you choose them.

• See how much light the area receives. Different plants have different light requirements. Choose plants that have the same light requirements to plant in the garden.

• Select plants that have the same water and soil requirements

• Decide if you want to use annuals. Annuals usually grow and bloom for one season and are broken into warm- and cold-season annuals.

• Consider using perennials. Perennials will usually give you several seasons, if not years, of blooms and growth.

• Shrubs will give you color and contrast throughout the seasons.

• Figure out how big each plant is at maturity. This will give you a better idea of how many plants you will require and how far to space them apart.

• Consider the placement of the plants and what look you are trying to achieve. Formal flower gardens will have all the plants lined up in a straight row. Flower gardens with a more natural flow will have the plants unevenly spaced throughout.

• Native flowering plants that grow in your region are a great addition to attract butterflies and for easier maintenance

• Consider using a focal point in your flower garden.

• How much time do you have for maintenance and care?

If you plan on starting with shrubs, here are some suggestions for color in gardens along the lakeshore vs. away from Lake Superior.

Hardy Summersweet (Clethra alnifolia) is a carefree shrub that no garden should be without. One of the best native American shrubs, Summersweet has everything. Carefree, with sweet smelling summer blooms of pink, white, or deep-rose, Summersweet is pest and disease free. Beautiful when planted in
mass or as a foundation plant. Prefers slightly acid, sandy soil and full sun, but tolerates clay and dense shade. Late summer/early fall bloom. Zone: 3-9. Height: 4-6 feet.

Autumn Magic Black Chokecherry has glossy dark green foliage with an upright shape. Does well in full sun and partial shade. Fragrant white flowers in spring followed by clusters of large dark purple-black berries that persist through the season. Leaves turn reddish purple in the fall. 3-5’tall and 2-4’ spread. Zone: 3-7

Saskatoon Boxwood is for those folks who really miss having a boxwood in their garden. It has done well for three years, is a slow growing evergreen shrub that is easy to prune and has not been decimated yet by the deer. Zones: 4- 8 It will grow about 2 feet tall and spread 2-3 feet.

Pygmy Peashrub works well for a nice short hedge or backdrop for smaller flowers. It stays a light green and has small yellow flowers in spring. Great for difficult soils and dry areas. Zones: 3 – 7. It grows about 3-feet tall and spreads 4-5 feet.

Tom Thumb Creeping Cotoneaster has shiny miniature leaves and beautiful herringbone branching pattern. Great fall red color it grows 8 – 12 inches tall and spreads out about 4- 6 feet. Nice in dry soils and full sun and works great along the edge of the rock garden. Zones: 4-9.

Twist & Shout Hydrangea has dark green leaves that turn burgundy-red in the fall. Blooms on new and old wood with lacy, deep-pink centers surrounded by pink or blue blossoms. Grows 3-5 feet tall and 3- 4 feet wide. Nice specimen plant. Zones: 4-9.

Other suggestions might include: Dart’s Gold Ninebark, Nugget Ninebark, Rhododendrons, Lilacs, Spireas, Viburnums, etc.

Here are some new Introductions from Bailey’s Seeds to consider

Hydrangea arborescens Bella Anna (‘PIIHA-I’)-- Part of the Endless Summer collection, Bella Anna features large, peppy pink blooms. Harsh winter weather or severe pruning is not a problem for Bella Anna. This hardy, reliable hydrangea keeps blooming from early summer through fall, with minimal care. Grows 3 feet tall and wide. Full sun to partial shade. Zones 3–9.

Rosa Pinktopia (‘BAImas’ )--Pinktopia, an Easy Elegance rose, packs masses of dreamy medium pink blooms against dark green leaves. Pinktopia’s new growth is a stunning red. It makes a great low-maintenance accent plant or
hedge. Recurrent bloom cycle. Grows 4 feet tall and 3 feet wide. Zones 4–9.

Rosa Sigrid Rose (‘UMNsigrid’) --This Northern Accent beauty boasts enormous clusters of red double blooms. Reaches just over 3 feet with inch-wide double flowers. Everblooming. Zones 4–9.

Physocarpus opulifolius Little Devil (‘Donna May’)--An exciting improvement in ninebark, First Editions Little Devil resists pests and diseases and requires very little maintenance. It keeps its compact shape without pruning, making it great as a background or in a shrub border. Grows up to 4 feet tall and wide. Full sun or part shade. Zones 3–7.

Hydrangea paniculata Tickled Pink (‘HYPMAD II’) --Tickled Pink’s cone-shaped blossoms start out soft white then gradually turn a rosy pink.

Dividing Perennials – Rule of thumb: Divide fall blooming plantsin the spring and spring blooming plants in the fall.
Iris (6 weeks after blooming); Peonies (late August); Daylilies (after blooming – late August)

Annuals are usually an important part of any flower garden, too.
Cool-season annuals are those that like 70 deg. days and cool nights.
Warm-season annuals are those that like 80 – 90 deg. days and nights in the 60 – 70 deg. range.

Annuals can also be categorized according to their temperature tolerance. They are often categorized as very hardy or hardy, half-hardy, tender and warm-loving.

Very hardy - withstanding temperatures down to 20 deg. F. Bloom early in spring and late in fall during cooler temperatures. Direct seed in cool ground for germination. May retreat Or die-off when temperatures become very hot.
Hardy – withstanding temperatures down to 30 deg.
Half-hardy – tolerate long periods of cold, wet, damp weather but can be damaged by frost. Will usually have earlier and later bloom periods during cooler weather. Can self-seed.
Tender – plant when all danger of frost is over; won’t germinate under 60 deg. and are usually native
to warm tropical regions of the world. Bloom during July & August, don’t usually self-seed. Warm-loving - like 80 degree days.

Combinations of annuals that work well together
• Long bloom period / or bloom periods that complement each other
• Color and contrast of flowers and foliage (repetition)
• Pick up colors of home, deck where you are going to be placing container / window box
• Different heights / styles / textures (repetition)
• Culture conditions are similar – temperature, sun exposure, etc.

Some suggestions for annuals that will re-seed themselves
• Bachelor buttons
• Calendula
• California poppy
• Candytuft
• Cleome
• Cosmos
• Dianthus
• Forget-me-not
