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. The extraordinary blooms are loaded with petals that curve, giving Tickled Pink a lacy, flirty look. Grows 4 to 5 feet tall and spreads 5 to 6 feet. Full Sun. Zones 4–8.

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
• Four-O-Clocks
• Johnny-Jump-Ups
• Larkspur
• Love-in-a Mist
• Moss rose

• Fig hollyhock
• Poppies
• Black-eyed Susan
• Cardinal flower
• Columbine
• Delphinium
• Foxgloves
• Echinops ritro

• Sweet William

Cook County Extension has put together a “Guide to Some Annual Flowers 2010” and is currently working on a new, revised recommended perennial list. Call 387-3015 for more information.


Seed catalogs are available by mail and may be found online, too.

Planning This Year's Garden

NorGard_010611.mp3109.94 MB

The Northwoods Food Project and Cook County Extension together with WTIP produce Northern Gardening, a radio show about gardening in Cook County.
Northern Gardening will air on the second Thursday of each month through March and then the second and  fourth Thursdays from April through October. We will be focusing on a variety of issues and topics that our listeners are interested in learning more about.

If you have a topic you would like discussed, call Diane Booth at 387-3015 or email
This week's hosts were Diane Booth and Joan Farnam with guest Buck Benson.
The following are notes used during the show which might interest our listeners.

We love this time of year when the seed catalogs arrive with all the new, shiny photographs of lush spinach and mouth-watering tomatoes. Anything seems possible in January!

Before you start ordering seeds though, there’s the inevitable Seedbox Organizing Event or Taking Inventory where you go through last year’s seeds and see what you have.
Divide the seeds into several groups:
winter sowing,
seeds that need to be started in the garden,
seeds that need to be started 8 to 10, 4 to 6, or 2 to 3 weeks before last frost

The Cook County Extension office has a pamphlet which gives you the approximate time that seeds remain viable, but it’s always a good idea to do a germination test before planting.
Place 10 seeds from a packet between layers of moist toweling and see how many germinate. If 70 percent, or 7 seeds germinate, you know how much you should plant to get a good stand this year.

And now you’re ready to look at seed catalogs and make your choices. There are lots of seed catalogs out there which specialize in short-season varieties as well as larger seed companies that include short-season choices as well. A few names include Seeds of Change, Baker Creek Heirloom Seeds, FedCo , Johnny's Select Seeds, Jung Seed Company, Pine Tree Garden Seeds, Gurney's Seeds, Burpee Seeds, Stokes Seeds to name a few.
Chose Vegetables/ flowers that are acclimated to our northern climate. They should be short season varieties (60-70 days) for vegetables and flowers you plan to start from seed. If you’re starting the seeds indoors and plan to transplant, then you can get varieties with a little longer maturation date.
We checked out the median cates of critical low temperature thresholds in Minnesota at, which reports frost dates from 57 years. The site reported that in Grand Marais, the median last day of frost in the spring was May 16 and the median first day of frost in the fall was Oct. 1, leaving 137 growing days.
At the Duluth Airport, on the other hand, which would be equivalent to gardens about one mile from Lake Superior, the last day of frost in spring is May 17 and the first day of frost in fall is Sept. 23, leaving 125 growing days.
So choosing your varieties carefully is important for gardeners on the North Shore.

Seed Saving:
Another important question to ask before you purchase seeds is whether you plan to save seeds for next year’s garden.
If you are saving seeds you probably don’t want to purchase F1 hybrids. If you get open pollinated or heirloom seeds, they will grow the same variety year after year. It’s also important to find out if our season is long enough for the plants to produce mature seeds in that first year.
Another important factor is whether the seeds are wind-pollinated, insect-pollinated or self-pollinated.
Squash and pumpkins, for example, can cross with each other if they’re planted too close together, and you’ll get hybrid seeds. However, there are different species of squash which do not cross-pollinate, although many seed packets don’t tell you what they are. You need to know the genus and species to know which varieties will or won’t cross-pollinate. There are three species of squash -- C. pepo, C.moschata, C. maxima. C. pepo can be planted next to C. moschata without cross-pollination, for example.

Many people these days are interested in buying organic seeds and more and more seed companies are providing this option to their customers.
One seed company in particular, Seeds of Change ( provides organic seeds, and they regularly test their seeds for genetic engineering contamination.

Here’s a list of some vegetable varities from Seeds of Change that would probably do well in Cook County. The seeds can be ordered online and are also found at Buck’s Hardware.


Maxibel (50 -55 days) ‘haricots verte’ fresh eating
Provider (50-55 days) cold tolerant, good frozen, canned, dried
Blue Lake (50 – 60 days)
Beurre de Roquencourt (H) (55-60 days) vining tendencies
Indian Woman Yellow (H) (60 – 75 days)
Hutterite (H) (75-85 days) great soup / chowder bean


Alvro Mono (55-65 days) One seed beet earlier than moneta
Touchstone Gold (45 baby – 60 days)

Nutri bud (55-70 days) good side shoot production
Early Green (60-70 days) good side shoot production

Scarlet Nantes (65-75 days)
Kurota Chantenay (80 – 90 days) 5-8” roots in heavy soils / good
Yellowstone (70 – 75 days) 8- 10” Danver’s type

Cassius F1 (65 – 70 days)

Rhubarb (50 – 60 days)
Golden (50 – 60 days)

You should aim for less than 70 days and/or a short-statured corn that will grow 4- 5’ tall.
*Triple Play (60 -70 day) SU yellow ripe, blue sweet.

Oriental, under 70 days

Gourmet Greens
Most greens do well here. Kales are becoming much more popular as are mustards, tatsoi
Sputnik arugula
(30 – 40 days) 3-8” leaves

 King Richard type, (75-85 days), does not overwinter

Lettuce Look for long growing varieties that resist bolting, bottom rot, tipburn in warmer weather, etc. Mixes are great for cutting. Choose Mesclun, greens or lettuce mixes.

Flint, (28-50 days) green leaf
Nevada, (50 -55 days) summer crisp
Concept, (28 – 50 days) summer crisp
Galactic, (28 days) red summer crisp
Winter Density (55-65 days) mini-romaine
Icaro, (55-65 days) green butterhead

Not more than 80 days usually but depends upon your growing situation. They need heat and probably won't do well if your garden is next to Lake Superior, unless you cover them.

Sugar Snap (60 – 70 days) 4-5’ vines

Generally under 70 days for our weather.
Bendigo F 1 (55-65 days) green to red fruit – would try this one

Desiree, (95 – 100 days) 4-6” x 2.5” red skin / gold
Bintje, (110 – 120 days) gold skin / white
German Butterball (105-115 days) golden skin / yellow

Plum purple, (20-30 days)

Tyee F1, (45 days) bolt resistant

Gold Nugget, (75-95 days) C. maxima
Delicata Zeppelin, (90-100 days) C. pepo
Uchiki Kuri, (90-100 days) C. maxima

Young’s Beauty, (95-110 days) 8 – 12 lbs /pie/jack 'o lantern, C. pepo

Bedtime for Northern Gardening

NorGard_EDIT_102110.mp3108.86 MB

Northern Gardening is "put to bed" for the season in this show, although it will come out of "hibernation"' in January to talk about ordering seeds and great varieties for Cook County. In this show, guests talk about bees and chickens  and getting them ready for winter as well as things to think about for the coming growing season. We also talk about recipes for fall produce. To listen, click on the audio icon.

Here are a few recipes submitted by our guests and radio fans.

Apple Butternut Squash Soup

Serves 6
* 1 tablespoon unsalted butter
* 1 medium onion, diced
* 1 butternut squash (about 2 pounds), peeled, seeded, and chopped
* 4 red or golden apples, peeled, cored, and chopped, plus 1 apple, finely diced and tossed in lemon juice, for garnish (optional)
* 2 teaspoons coarse salt
* 1 1/2 teaspoons ground cumin
* 1/2 teaspoon ground coriander
* 1/2 teaspoon ground ginger
* 1/4 teaspoon cayenne pepper
* 1/4 teaspoon freshly ground black pepper
* 2 cups homemade or store-bought low-sodium chicken or vegetable stock
* 2 1/2 cups water, plus more if needed
* 1 jalapeno chile, thinly sliced, for garnish (optional)
* Sour cream, for garnish (optional)

Melt butter in a large saucepan over medium heat. Add onion; cook, stirring occasionally, until it begins to soften, about 4 minutes. Add squash, and cook, stirring occasionally, until soft, about 10 minutes.
Add apples, salt, cumin, coriander, ginger, cayenne, black pepper, stock, and the water (just enough to cover). Bring to a boil. Reduce to a simmer, and cook until vegetables are very soft, about 30 minutes.
Puree in batches in a food processor or blender until smooth, and return to saucepan. Heat over low, thinning with more water if necessary. To serve, ladle into shallow bowls; garnish with diced apples, jalapeno slices, and sour cream if desired.
I like to take a toothpick and swirl a pattern with the sour cream ontop of the soup. A little flare is always welcome!

Here are a few recipes for kale lovers.

Baked Kale Chips

Kale chips can be crumbled over popcorn for a tasty, nutritious snack.


  • 1 bunch kale
  • 1 tablespoon olive oil
  • 1 teaspoon seasoned salt
  1. Preheat an oven to 350 degrees F (175 degrees C). Line a non insulated cookie sheet with parchment paper.
  2. With a knife or kitchen shears carefully remove the leaves from the thick stems and tear into bite size pieces. Wash and thoroughly dry kale with a salad spinner. Drizzle kale with olive oil and sprinkle with seasoning salt.
  3. Bake until the edges brown but are not burnt, 10 to 15 minutes.

Kale Crisps

This recipe includes cheese.  Both of these recipes are from


  • 2 bunches kale, washed and dried
  • 2 cups shredded Cheddar cheese


  1. Preheat oven to 425 degrees F. Spray 2 baking sheets with cooking spray.
  2. Remove the stems and ribs from the kale, and shred the kale very thinly. Spread the shredded kale onto the baking sheets, and sprinkle evenly with Cheddar cheese.
  3. Bake the kale for 10 minutes, watching carefully to prevent burning, until the kale is crisp and the cheese is browned.

Butterfly Gardening and a greenhouse for Great Expectations School

NorGard_100710.mp3109.81 MB

The Oct. 7 Northern Gardening show featured Karina Roth and Kaitlin Erpestad who talked about youth gardening and the new greenhouse at Great Expectations School, and Max Linehan, who talked about gardening for wildlife, which she has successfully done in her garden in Hovland.
Pictured at left  is one of the monarch butterflies which hatched in her garden this summer.
Hosts Joan Farnam and Ann Rosenquist also discussed great ways to cook winter squash with their guests.
To listen to the program, click on the audio link above.

Here are Max Linehan's notes for her presentation:

"Most gardeners look at plants as ornaments…try looking at what the plants do as part of
the environment. When we design our landscapes only for aesthetics, we put in pretty
plants and if we see an insect, we kill it. That’s an extremely artificial environment, not a
living, changing ecosystem.

"We have a serious extinction crisis on our hands. Ninety percent of all birds rear their
young on insects. That’s why we don’t see songbirds at our seed feeders during the
weeks of midsummer. They are feeding their nestlings exclusively on the protein
rich insects the babies need to develop quickly into strong fledgelings. If there are no
insects, there will be no birds. In fact, in the last fifty years we have lost half our songbird

"If nature is to survive, it will have to be in our yards and parks. In the lower forty-eight
states we have taken 41% of the land for agriculture and 54% is under cities, highways,
factories and such. That leaves us with 5% of the original wilderness habitat in scattered
pockets throughout the states. For our own good, we humans need to share.

"Consider a lawn…. It’s a pretty barren place compared to the forest or prairie it used to
be, supporting about three species of wildlife compared to a native oak which supports
over 500 species of butterflies and moths alone, plus many other insects and other
animals. Willows are right behind the oak by supporting over 450 species of butterflies
and moths. Other excellent native trees are cherry and plum, birch, poplars, maples and
box elders, pines, hickory, hawthorn, alder, spruce and ash.

"When we plant exotic species of trees, shrubs and flowers from other continents they do
not participate in the local food chain or web. Our wildlife does not recognize them as a
food source, and usually has not even evolved a digestive system to utilize them. These
exotic species may as well be plastic. There is always the risk that the alien plants can
escape our gardens and become part of the 3400 invasives we already have. Also, exotic
imported plants sometimes carry with them invasive insects or diseases that become a
problem spreading out of control.

"Any time we can plant native trees, shrubs and flowers to diversify our landscapes we are
bringing nature back. Planting native trees has the biggest long-range effect. The Soil and
Water Conservation Dept. helps by making economical bundles of tree and shrub root stock
available for sale every spring. Last spring I planted twenty-some hazelnuts on our
five acres and was delighted to see their bright red fall color. But, like pines and cedars,
they have to be protected from the deer until they are tall enough. Native plant nurseries
like Boreal Natives in Cloquet, and Prairie Moon Nursery in Winona can provide trees
and shrubs in smaller numbers. Both nurseries also supply a wide variety of wildflower
species as seeds, root stock or started plants.

"Butterfly and hummingbird gardens are a great way to bring nature into your yard. Cook
County extension agent Diane Booth has a wealth of information on choosing plants and
a site, and setting up such a garden. Prairie Moon Nursery’s catalog and website has lots
of information on flower species and their preferences. More species-specific information
is available at the Monarch Watch website.

"Providing for butterflies, moths, bees and other pollinators is a first step toward tolerating
other interesting insects in one’s yard.

"Butterflies need to land on flowers to sip nectar, so “platform-like” flowers such as
daisies, zinnias and coneflowers are best for them. You will find hummingbirds will
use your butterfly nectar flowers as well as the tubular flowers you plant for their use.

"Be sure to include in your butterfly garden food plants for the caterpillars as well as
nectar plants. Some plants, such as swamp milkweed will provide both nectar and
caterpillar food. Parsley, dill and other plants in the carrot family will be visited by
swallowtail butterfly caterpillars. Last spring they ate all my dill and parsley, but by
late summer the parsley grew back for me to use. One thing I learned about butterfly
gardening is to place plants closer together, maybe one per square foot. That way the
caterpillars have more protection from predator birds, and can easily travel from their
food plant to a different plant where they can attach their chrysalis. You will also notice
spiders preying upon the smallest caterpillars. I found myself moving more than one
daddy long legs to a different place in my garden, but that’s just my reluctance to fully
accept nature’s food web!"

Northern Gardening, hosted by Diane Booth and Joan Farnam, featured an interview with Margaret Plummer, interpreter and gardener for the Grand Portage National Monument Heritage Garden on Sept. 16. The program also featured discussions on fall gardening with Ann Rosenquist, CSA grower and University of Minnesota Master Gardener.

Following are notes and bits of information prepared by Diane Booth for the show. To hear the broadcast, click on the link.

The next program will feature Max Linehan, who will talk about butterfly gardening, and we’ll have an update on the Grand Marais Community gardens. We’ll also continue with tips on final steps in getting your garden ready for winter. That show will air Thursday, Oct. 7 at 4 p.m. The last show of the season is Thursday, Oct. 21.

Do you have questions, suggestions? E-mail us at


Here are the notes from the program that ran Sept. 16.


What are heirloom seeds?

A plant or seed variety that has been preserved by local growers or gardeners in a specific area where the seed has been selected over numerous years and saved. It can also be defined as a  variety that was in existence before 1951 when vegetable hybridization become more prevalent.


Questions to Margaret Plummer:

 Can you please share with us what you do at the Grand Portage National Monument.

• Tell us about the varieties you grow

• Where you purchase your seeds from

• What varieties you save seed from

• Growing methods you use in the heritage garden.

• Three Sisters garden: corn, squash, beans (note: The Three Sisters Garden is an Iroquois term for life support)D

Do you grow herbs?  Tobacco?


About Corn:


Dent corn – Zea mays indenata ‘field corn’ for livestock or making processed food. Contains both hard and soft starch. (white or yellow). Dried and ground to use for cornstarch.

Flint corn – Zea mays indurata ‘Indian corn’ used for similar purposes as dent corn but has a harder outer shell and kernals with range of colors. Harvest when kernels are dry and husks are no longer green.

Sweet corn – Zea saccharata or Zea rugosa primarily eaten on the cob or frozen, canned for later use. Extra sweet.

Flour corn – Zea mays amylacea used in baked goods with soft, starch-filled kernel that is easy to grind. Flour corn is primarily white but can be blue. Dried and ground into meal.

Popcorn – Zea mays everta a type of flint corn with a soft starchy center surrounded by a hard exterior shell. All types of corn will pop to some extent but not as much as popcorn.


 Different types of squash


The genetic history of the pumpkin is so intertwined with the squash and the gourd that it's sometimes difficult to tell them apart. Generally speaking a pumpkin is something you carve, a squash is something you cook, and a gourd is something

you look at. Though it's really not that simple, it's also not that difficult. The answer is in the stem.


Pumpkins and squashes and gourds all belong to the same genetic family - Cucurbita. Within that family are several species or subgroups - Cucurbita pepo, Cucurbita maxima and Cucurbita moschata.


The Cucurbita pepo species is usually recognized as the true pumpkin. Varieties within this group have bright orange skin and hard, woody, distinctly furrowed stems.

But the group also includes gourds, vegetable marrow, Patty pan summer squash, scallop summer squash, gray and black zucchini and summer crookneck squash.


The Cucurbita maxima species also contains varieties that produce pumpkin-like fruit but the skin is usually more yellow than orange and the stems are soft and spongy or corky, without ridges and without an enlargement next to the fruit. They don't really make good handles for jack-o'-lanterns. Varieties such as Atlantic Giant, Big Max and Show King are often listed as pumpkins but are more properly called pumpkin-squash or squash- type pumpkins. Other members of the maxima group are Hubbard squashes, banana squashes, buttercup squashes and turban

squashes - in short, most autumn and winter squash.


Finally, there's the Cucurbita moschata species. Varieties in this group are usually long and oblong instead of round and have tan rather than orange skin. The stems are deeply ridged and enlarged next to the fruit. Ironically, a member of this group is used for much of the canned pumpkin sold in this country. Other non-pumpkin members include the squash-like cushaw and winter crookneck squash.


Squash blossoms -- use extra blossoms in fall when you want to slow down production of quash (summer or winter).


Fall Gardening


There’s a long list of things we all probably do in our fall gardens, but planting and growing garlic is a great project. 


Types of garlic

Hardneck vs. softneck – Hardneck varieties produce a flower stalk or scape that usually form bulbils. Hardneck varieties do not store as well as softneck. Softneck varieties do not produce a seed stalk. Longer shelf-life and easy to braid.


Softneck Varieties:

Artichoke types may bolt in cold winters, white to purplish – Inchellium Red, California Early, Susanville

Silverskin types are a true softneck type even under Minnesota conditions. Best in warm climates and mild climates. Silver White, Nookota Rose, Mild French,


Hardneck Varieties:

Racambole types usually have purple or purple streaks that are 3-4’ tall with uncurled scape –German Red, German Brown, Spanish Roja, Russian Red Purple stripe – 3- 5’ tall, uncurled scape, purple bulbils – Chesnok Red, Persian Star

Porcelain – large 4- 6’ tall plants, random coils of scape that straightens out.

Bulbils numerous, bulbs white – Music, Georgian Crystal, Polish Hardneck, Zem White, etc.

Asiatic types is a shorter 3’ tall plant thought originally to be a softneck type but current thought is it is a hardneck. Asian Tempest, Japanese, Sakura.


Growing garlic

Garlic needs well-drained soils with high organic matter

pH greater than 5.8

Loose bed for bulb growth

Cloves are used for propagation since true seeds are not produced by the garlic plant

Dig plants up when more than half of the leaves turn brown, tie in bundles 10 -1 5 and hang to

dry about 3 – 4 weeks

Store cloves at 32 – 40 degrees with 60 – 70% humidity

Plant in the fall usually within one – two weeks after the first killing frost (32 deg.)

(Usually the third or 4th week of September here)

Separate individual cloves from the bulb 1- 2 days before planting or longer so they may dry out.

Base of clove should be planted 2- 3” below soil surface.

Mulch well after the ground begins to freeze.

Planting Bulbs this fall

Daffodils - deer resistant, tendency to be more perennial here

• Look for weight – sometimes they are single or double-nosed

You want the largest sized bulbs you can get

• Desiccation and mold become issues on store shelves

• There are 13 different divisions of daffodils:

Trumpets – Dutch Master, King Alfred, Mount Hood

Long-cupped – Ambergate, Fragrant Rose, Mrs. R.O. Backhouse, Stainless


Double – Cheerfulness, Erlicheer( forcing)

Triandrus – ‘whimsical’, smaller usually – Thalia (Orchid narcissus), Petrel

Cylamineus – Jenny, Peeping Tom

Jonquilla – most fragrant, smaller – Pipit, Sweetness (will force)

Tazetta Paperwhites – forcing – Grand Soleil d’Or (yellow & orange great fragrance), Ziva

(not cold hardy)

Poeticus – Actea

Bulbocodium – Golden Bells ‘hoop petticoat form’

Split-corona – palmares (lt. salmon & white)

Miscellaneous – Tete-a-Tete (6” tall, fragrant, early, will force, naturalize)

Planting daffodils

Plant 6 – 8” deep or 3 times the height of the bulb

Plant by the end of September if possible to develop a good root system before winter

 Must have full sun, good drainage and not too much nitrogen

 Don’t cut their leaves after blooming until they die back

Tulips – critters love, plant in larger wire mesh like chicken wire, last one to a couple of seasons

Look for weight – they are sized according to cms in circumference

They can be planted up until the ground freezes



There are many different types:

Kaufmanniana tulips – Z 2 short 6 – 10”

Single early tulips – 10 – 18” stems – Apricot Beauty, General de Wet (orange/yellow)

Double early tulips – 8- 12” stems – Mr. Van der Hoeaf (yellow), Schoonoord (white)4.

Fosteriana tulips – ‘Emperor’ tulips –

Gregii tulips – eye catching foliage with stripes, shorter – Red Riding Hood

Darwin Hybrid tulips – one of best varieties for perennializing – Big Chief (salmon rose 24”),

Hollands Glorie (carmine red), Silverstream (creamy yellow with rose and red + pink and white

margined foliage.)

Triumph tulips – some of best for forcing – 10 – 22” Shirley (white blooms edged with purple)

Viridiflora tulips – green markings on petals, great for long lasting displays and cut flowers –

Fringed tulips – ‘tulips to touch’ 18 – 24”

Lily flowered tulips - Queen of Sheba (Mahogany red blooms dipped in gold), White


Double Late tulips – ‘peony-flowered tulips’- Angelique (pale pink & darker pink)

Parrot tulips – ‘whipped petals’ –

Single late tulips –most popular for consistent – Cashmir(bright red), Dreamland (White with

deep rose and light pink) Mrs. J.T. Scheepers (pure yellow) Queen of the Night ( ‘black tulip’)

Multi-flowered tulips - 4- 6 tulips per stem – they bloom from early through midseason

Orange bouquet,


Tulip Species 


Liliums: Asiatics, Orientals, Aurelian Trumpets, Orienpets (Orientals x trumpets)

Camassia, Crocus (Jeanne d’Arc), Eremurus ‘Fox tail Lily or Desert Candle’, Galanthus ‘Snowdrop’

Hyacinths (Hyacinthus orientalis) Muscari ‘Grape hyacinth’ Pushkinia ‘Striped Squill’

Things to do in your fall garden besides saving seeds, planting garlic or bulbs

• Plant a winter cover crop so you won’t have bare soil in the garden over the winter.

• Start some lettuce, spinach, kale, tatsoi or other hardier greens in your cold frame or hoops covered with

reemay / plastic to extend your growing season.

• Repot your houseplants or annuals that have been outdoors and remember to start bringing them in according to those that are most sensitive to the cold.

• Once frost has killed the foliage on perennials, remove all blackened and diseased foliage / stems.

• Cut back and remove the 2-year-old canes (fruiticanes) on your raspberries

• Protect young fruit trees or thin-skinned trees like maple by placing cylinders of fine hardware cloth around them. This prevents sunscald and deer or mice from nibbling on them.

• Protect any vulnerable ‘deer food’ with fencing for the winter like arborvitae, hostas, yews, azaleas – browse the deer loves in the winter.

• If you have raised beds, mulch perennials, asparagus, etc. with straw or leaves covered with balsam boughs just before the snow flies.

• Water, water, water everything into the fall so your overwintering tree, shrubs and perennials go into the winter with enough moisture.


Keep pace with the weather by lifting or harvesting tender bulbs and corms that are desired for next season. These would include but not be limited to glads, dahlias and tuberous begonias. Many can be enjoyed right up until a good frost blackens their tops. Be sure to dig the bulbs carefully, retrieve any offsets that may have developed, and leave the foliage intact.


Place the bulbs in an airy, sheltered spot to dry for a two to three week period. Except for begonias, foliage and stems can be cut off with a sharp knife near but not at the point where they emerge

from the bulb. Allow begonia stems to dry until they are brittle enough to break off from the bulbs.

The bulbs will overwinter well in a dark, cool place (45 to 50 degrees F.) when stored in vermiculite, peat moss, or similar material. It is also recommended to dust with a fungicide (Bordeaux mixture) and insecticide (Sevin dust) to curb disease and insect development in storage.


Two plants which will require special care after their summer outdoors are the poinsettias and Christmas cactus. Both have similar requirements in that they need a 14-hour period of continuous darkness each day from October 1 until mid-December to set flower buds. Two methods to accomplish this are to

either set the plants in a closet or place a cardboard box over them from 6 p.m. until 8 a.m. for the period listed above. At all other times, the plants should receive normal light exposure.

Seed Saving and Planting for Fall

NorGard_THURS_090210.mp3108.75 MB

Nick Wharton, who runs a CSA in Cook County and Jerry Goettl, the founder and owner of Baker Creek Heirloom Seeds, a rapidly growing heirloom seed company based in Missouri, talk about seed saving with Diane Booth, Melinda Spinler and Joan Farnam. Heirloom seeds are becoming more and more popular across the nation, as is saving seeds from heirloom plants. 



All about Root Cellars

NorGard_081910.mp3109.81 MB

Guests on Northern Gardening discuss root cellars -- how they're built, what can be stored in them and more.
John Fishesr-Merritt from the Food Farm in Wrenshall and John Quist ist from the Oliver Kelly Historic Farm near Elk River talk about their root cellars. The one at the Oliver Kelly Farm is the oldest in the state, built in 1850. The Food Farm ships its carrots up to the Cook County Whole Foods Co-op in the winter.



Recent recipes: basil pesto, garden veggie pesto pasta and chipotle brownies

Here are three recipes recently submitted by Northern Gardening fans.
Do you have a favorite using vegetables from your garden? Send to and we'll post it here.
P.S. The Chipotle Brownie recipe doesn't really qualify unless you're growing anaheim chilis and smoking them yourself, but I thought people might be interested to try it. They've gotten rave reviews.

Fresh Basil Pesto

Submitted by Ann Rosenquist, Grand Marais

2 cups fresh basil leaves, packed
1/2 cup freshly grated Parmesan Reggiano or Romano cheese (leave out cheese if freezing)
1/2 cup extra virgin olive oil
1/3 cup pine nuts, walnuts or roasted, unsalted sunflower seeds
3 medium-sized garlic cloves, minced
Salt and freshly ground pepper to taste

A food processor makes this a lot easier.

Combine the basil with the nuts and pulse a few times in a food processer. Add the garlic, pulse a few times more.
Slowly add the olive oil in a constant stream while the food processor is on. Stop to scrape down the sides with a rubber spatula. Add the grated cheese and pulse again until blended. Add a pinch of salt and fresh ground black pepper to taste.
Makes 1 cup.
Serve with pasta or over baked potatoes, or spread over toasted baguette slices.

Garden Veggie Pesto Pasta
Submitted by Becky Stoner, Grand Marais 


1 pound of your favorite pasta ( I use rotini so it holds more pesto)
olive oil
parmesan cheese
pine nuts
2 cups of your favorite garden vegetables, cut up small ( I like carrots, broccoli and cauliflower for color and texture)
1/2 to 1 c pesto to taste

Cook the pasta for 2 minutes less than the full time listed on the package.
Keep it in the pan and add the vegetables to the pasta and boiling water for that last 2 minutes and turn up the heat.
Drain pasta and vegetables. Do not rinse.
Return them to the pan and add pesto and some some olive oil to dilute the pesto a little. Stir to blend.
Add pine nuts and parmesan cheese in it or on top, to taste.
Vary the amounts based on what you like. Eat hot or cold.
For leftovers ( if there are any!) store well in fridge and reheat with a little water added.

Cilantro pesto butter

Staci Drouillard, Grand Marais

I just whir up the cilantro in a food processor with some green onions, garlic, S&P, fresh jalepenos to your liking and lime juice. When it's a paste I drizzle in some olive oil. Then I mix it up with a pound of soft butter and make small portions of it for the freezer. It's DELICIOUS on grilled fish, on vegetables, pasta, steak, you name it!!!

Tomatoes and Tarragon

Ann Possis, Lutsen

Fresh tomatoes and lots of fresh tarragon, dressed with the best mayo you can find, and a teeny bit of Lawry's seasoned salt.

Easy Sauerkraut

Mary Igoe, Grand Marais

Ingredients: Cabbage (the amount depends on how much you want to make)

Canning salt


Shred cabbage and pack tightly into quart jars up to 1/2 inch from the top. This is easiest with a wide mouth jar.

Add 1 teaspoon each of canning salt and sugar to each quart.

Pour in boiling water to cover the cabbage.  Gently insert a knife in the jar to remove any trapped air.

Put on canning lids and screw on LOOSELY.  Put the jars in a sink or pan, as they may bubble over. Let ferment for 24 hours.

 Remove the caps, spoon off any scum that may have formed and add boiling water as necessary to cover the cabbage.  Seal as TIGHTLY as you can with your hand.

 Let ferment for 3 days.  This does not smell like fresh roses, so you may want to put it in the basement or some less traveled part of the house.

After three days process for 20 minutes in a boiling water bath.  Store a minimum of three weeks before eating.

Cabbage Salad with Peanuts

Mary Igoe, Grand Marais

In a large bowl, mash together:  1/4 cup natural, unsalted peanut butter  and 1/2 cup hot water

Add:  1/2 cup plus 1 TBSP rice or cider vinegar (rice is best)

        3 TBSP brown sugar

       1 1/2 tsp salt

       1 TBSP soy or tamari sauce

       1 tsp sesame oil

Add:  7 to 8 packed cups of shredded green cabbage.  Mix well

Sprinkle in and mix: crushed red pepper, to taste

Cover the bowl tightly and refrigerate for a minimum of 4 hours, stirring it every once in a while.

Sprinkle with 1/2 cup peanuts right before serving (I serve the peanuts in a separate bowl and everyone sprinkles on their own to avoid soggy peanuts in the leftovers.)

This is rather soupy, so serve with a slotted spoon.

Fresh Basil Pesto
Submitted by Ann Rosenquist

2 cups fresh basil leaves, packed
1/2 cup freshly grated Parmesan Reggiano or Romano cheese (leave out cheese if freezing)
1/2 cup extra virgin olive oil
1/3 cup pine nuts, walnuts or roasted, unsalted sunflower seeds
3 medium-sized garlic cloves, minced
Salt and freshly ground pepper to taste

A food processor makes this a lot easier.

Combine the basil with the nuts and pulse a few times in a food processer. Add the garlic, pulse a few times more.
Slowly add the olive oil in a constant stream while the food processor is on. Stop to scrape down the sides with a rubber spatula. Add the grated cheese and pulse again until blended. Add a pinch of salt and fresh ground black pepper to taste.
Makes 1 cup.
Serve with pasta or over baked potatoes, or spread over toasted baguette slices.

Garden Veggie Pesto Pasta
Becky Stoner, Grand Marais 


1 pound of your favorite pasta ( I use rotini so it holds more pesto)
olive oil
parmesan cheese
pine nuts
2 cups of your favorite garden vegetables, cut up small ( I like carrots, broccoli and cauliflower for color and texture)
1/2 to 1 c pesto to taste

Cook the pasta for 2 minutes less than the full time listed on the package.
Keep it in the pan and add the vegetables to the pasta and boiling water for that last 2 minutes and turn up the heat.
Drain pasta and vegetables. Do not rinse.
Return them to the pan and add pesto and some some olive oil to dilute the pesto a little. Stir to blend.
Add pine nuts and parmesan cheese in it or on top, to taste.
Vary the amounts based on what you like. Eat hot or cold.
For leftovers ( if there are any!) store well in fridge and reheat with a little water added.
