GROWING HEIRLOOM PEAS ORGANICALLY

Standard

Above: The Blue-Podded Pea, dating to before 1596

Peas love good, rich, moist loamy soils.  Gypsum may be added to heavy clay soils to lighten them, and organic compost is excellent for building mountain and valley soils poor in nutrients.  Fish bone meal, alfalfa meal, and kelp meal are amendments that will provide the complete range of nitrogen, phosphorous and potash to your garden plot necessary for successful vegetable production.  Remember that organic soils are alive with microbes, so food tastes better, is more nutritious, and is safe to eat.  Also, organic soils capture carbon out of the air, reducing heating of our planet’s atmosphere. 

Peas have been grown as a garden crop for centuries and seem to have been a popular vegetable through all that time.  Several heirloom varieties of peas still exist:

‘Blauwschokker’ (Blue-Podded) pea is an ancient variety so old it was described in Gerard’s Herball  written in 1596.  Plants are very healthy and productive.  The pods can be eaten as snow peas when picked early, used as shelling peas later, and dry well for use as soup peas.  The vines of the Blue-podded pea grow 60 to 72 inches tall and require a trellis.

‘Alaska’ is an heirloom pea from 1880.  It is early, ripens all at once, and like many heirloom varieties will dry and keep well.  It is excellent for soup.  The vines grow about 30 inches tall.

‘Tom Thumb’ heirloom pea from 1854 is a miniature pea variety that does not need to be trellised.  The vines grow to 8 or 9 inches tall and are suitable for containers and for growing in cold frames early and late in the season. 

‘Lincoln’ is a famous variety from 1908 that is adapted to warmer American summers.  The vines grow to about 28 inches tall and the pods produce 8 or 9 peas each. 

‘Wando’ is very adaptable to differing climates.  It is more heat resistant than most peas and can be planted later.  ‘Wando’ dates to 1943 and the vines grow about 30 inches tall.

Because peas can take some frost, even while quite young, they can be planted early.  Some people living in milder climates than Montana’s plant their peas on St. Patrick’s Day; 17 of March. 

 Here in Western Montana we make our first sowing April 15 to 20 depending on the weather and the soil temperature.   A second sowing usually is made July 1 (after first crop is harvested.)  It is efficient use of space and easy picking if trellises are set up in the garden bed.  The first crop bears from around June 15 -July 1, and the second crop bears from about September 15-October 25.

Plant your peas in full sun for best production.  The ideal growing temperature is 55–70 F., with 60-65 F. being ideal (peas prefer cool weather).  The optimum soil pH for peas is 5.5-7.5.  Peas will germinate between 40-85 degrees F., but 60-75 F. ideal.  Germination may take 6-17 days.  Direct-sow pea seed 1 inch deep and 1 inch apart.  Plant a few extra at the end of the rows to fill in later as mini transplants.  

Water well; keep the bed moist, not wet.  For the second (midsummer) planting, plant seeds 2-3” deep 1 inch apart, otherwise the same as spring.   Do not let plants dry out at any time, especially during flowering!  Water peas early in the day only, allowing leaves to dry early in the day–steady moisture is best.    

Some pests of peas are: gophers, aphids, birds, mice, cutworms, mites, leafhoppers, cucumber beetles, pea weevils, and various caterpillars.   Powdery mildew can be troublesome also, especially if soil becomes dry and air circulation and sunshine is limited.

To harvest: pick peas when the first pods reach full size: 4”- 5”, not smaller.  Pick snow peas before seeds start to swell.  Snap peas need to be picked when pods are full size, fat, and round with peas inside.  Check and pick every 3 days to keep plants producing.  The first peas ripen at the base of the plant—remove them carefully to not damage plants.  The harvest period should be 4-6 weeks long, for each planting.  Pick all (ready) pods to keep vines producing.  After harvesting keep cool, in high humidity and out of the sun. 

Keep freshly picked peas cool, in high humidity and out of the sun.   Store them in a cool location or in the refrigerator.  Picked pods last only 5-6 days.  Peas do freeze well and most varieties dry and store well. 

 

APRIL NOTES

Standard

APRIL GARDENING CALENDAR GENERAL

This winter was a “longie” with lots of snow, a situation which voles love!   In our market garden we discovered damage from voles on Campanula medium (Canterbury bells)—just the ones stored in pots in sawdust, but not those in the ground.  Also some potted Primulas, strawberries, and Echinaceas were completely eaten.  It was the same case with these last few; plants in the ground were unharmed, those in pots in sawdust were eaten.  It may be because plants all stored together serve a sort of “banquet” for voles, while those in the ground, mixed in with other plants are harder for the little critters to find.  I am experimenting with inter-planting Fritillaria imperialis (Crown Imperials) with plants that tend to be vole favorites, to see if they will help deter them.  Fritillarias are very odorous, and rodents do not eat them. 

April tasks:

Finish pruning and grafting of fruit trees if not already done.  Plant grapes and other fruiting perennials, shrubs and vines; fertilize and prune raspberries and blackberries.  Start many flowers inside for transplanting out and direct sow the last hardy annuals.  Direct sow many vegetables late in the month and into May.  April is characterized by ups and downs in temperature—watch for frosts!  Protect frames at night and admit air daily.  Place row covers on newly transplanted, slightly tender plants. 

VEGETABLES

If not done already, sow indoors, for transplanting out early in the month: basil, cabbage, celery, tomatoes, broccoli, cauliflower, kohlrabi, head lettuce, artichokes, Brussels sprouts, Asian cabbage, leeks, greens.  After the 15th, sow watermelon, cantaloupe, squash, pumpkins and cucumbers into peat pots for easy transplanting. 

Direct sow these outdoors once weather permits and soil temperatures are above 45 degrees:  beets, arugula, carrots, caraway, celery, chervil, chives, cilantro, dill, fennel, thyme, oregano, sorrel, collards, mache, fava beans, cress, Jerusalem artichokes, kale, kohlrabi, cabbage, cauliflower, leeks, lettuce, mustard greens, rhubarb, turnip greens, onions, parsley, parsnips, peas, potatoes, radishes, salsify, scallions, spinach, Swiss chard.  Sow corn (after the 20th). 

Harden-off vegetables in frames, or by exposing them outdoors a few hours at a time.  Transplant the following hardy vegetables outside around the middle of the month (they can take some light frost): asparagus, broccoli, cabbage, cauliflower, Chinese cabbage, endive, leeks, lettuce, onion sets and plants, Asian greens, parsley.  

FLOWERS

Sow indoors April 1 for transplanting out: Chinese asters (Callistephus), Cerinthe, Celosia, Craspedia, Calendulas, annual Centaurea, Cleome, Cosmos, Cynoglossum, Eragrostis, Panicum, Pennisetum, and annual grasses.  Late in the month: sow zinnias indoors. 

Direct sow outdoors all month: annual alyssum Lobularia maritima), Bupleurum, carnations, pinks, sweet Williams, Cynoglossum, stocks, rose campion, wall flowers, Lychnis, lupines, lavateras, columbines, valerian, polyanthus, auriculas, Canterbury bells, hollyhocks, honeysuckles, rockets, honesty, fox gloves, snapdragons, sweet peas, poppies, larkspur, cornflowers, nigella, Lavatera, poppies, valerian, kiss-me-by-the-garden-gate, dill, morning glory, sweet peas and wildflowers.   

Weed and clean borders.  Divide perennials early in the month: carnations, Bellis, Achilleas, Asters, mums, Campanulas, Centranthus, Coreopsis, Dicentra, Dodecatheon, Echinops, Euphorbias, Gauras, Gaillardias, Gentians, Helianthus, hellebores, daylilies, Heucheras, Hostas, Lobelias, Papavers, Oenotheras, Phlomis, Monarda, Liatris, and Marrubiums. 

Start dahlia tubers this month and make cuttings if possible. 

Shade auricula primroses from intensifying spring sun.   This is when auriculas need the most water, but remember— never waterlog the compost.  The month of April is their peak bloom period and hybridizing can take place now.  Shows are held this time of year. 

FRUIT

By April 15, finish pruning /grafting/planting fruit trees; spray Bordeaux mix on fruit trees suffering from fire blight; check fruit trees for pests.  Spray superior oil on dormant trees (before leaf out).  Lime-sulfur will control anthracnose or blight on raspberries if applied when the buds first show silver, or on currants and gooseberries at bud break.  Wait three weeks if you decide to spray lime-sulfur (use caution) as a fungicide on roses, lilacs, dormant shrubs, fruit trees, evergreens. 

Weed fruit trees, strawberries, cane fruits.  Set out apple pest traps two weeks before bud break.

TREES, SHRUBS AND ROSES

Lay out lawns by either direct-seeding or purchase turf and roll it out.  If the weather gets windy and dry, water your new lawn frequently. 

Finish transplanting roses and other shrubs (the earlier the better).  Prune established roses after severe frosts.  Cut out all dead and crossed wood, and seal the cuts with water-based glue to prevent the drilling wasps from destroying canes.   Dress rose plants with Epsom salts, wood ashes, compost, manure, alfalfa meal, bone meal, kelp meal, bunt earth, spent hops, etc. , but keep fertilizers 2 inches away from the canes at the base of the plant.

ORGANIC GARDENING NOTES FOR EARLY SPRING

The ground is thawed in the valley and soon the foothills will be snow free.  As soon as the earth dries out and wet turns to moist, you can work up the soil.  Dry organic amendments can then be forked into your beds.  Organic blood meal (13-0-0) is an excellent source of nitrogen and is quickly taken up by plants.  Alfalfa meal (3-1-3) will enrich soil with a moderate amount of nitrogen, small amount of phosphorous, and a moderate amount of potash.  Ground fish bone meal (5-16-0) also contains moderate amounts of nitrogen, but is a terrific source of phosphorous.  

Well-rotted manure (usually about 3-1-1) will add a good amount of nitrogen and smaller amounts of phosphorous and potash, but adds lots of beneficial, moisture-holding organic matter.  Be careful in sourcing manure as it may contain high levels of salt (especially if sourced from feed lots).  It is safest to use one year old, well-rotted manure on food crops.  Too fresh of manure will burn crops and can contain pathogens.  In our USDA Certified Organic market garden we are only allowed to use manure from grazed land that is at least one year old; and it must be applied at least 120 days before crops are planted.   Another option is to use manure that has gone through a heat of at least 160 degrees F. for 3 weeks; this kills harmful pathogens.  Compost may be spread on a USDA Certified Organic farm or garden but it must be made only from vegetable matter—no meats, dairy products or eggs, etc.  

If you are starting a new garden bed, spread cardboard, rotted moist straw, or tarps to kill grass out.  Newspapers will dry up and blow away unless anchored by rocks or chunks of turf.  You can till right into the turf to prepare your spot, but weeds will be present and you will have to keep after them.  Try to till only once, pull weeds out, add amendments and mulch the soil until ready to plant.  Too frequent tilling destroys the structure of the soil and causes it to release carbon.

Remember that healthy organic soils are alive with microbes and fungi that help plants pull CO2 out of the atmosphere.  By gardening organically you are helping the earth to gather and store carbon dioxide.  This is exactly the opposite environmental effect of conventional gardening, which uses chemical fertilizers and often features bare soil.  Chemical fertilizers require large amounts of carbon to make and bare soil causes soil organisms to die; with the result that soils lose carbon rather than pulling carbon out of the atmosphere and storing it. 

Forest, grassland and hedgerow soils pull the most carbon from the atmosphere of any land ecosystems.  In your garden, you can help this process by setting aside areas for wildflowers and grasses, shrubs, shrub borders and shelter belts or groups of trees with wildflowers and/or groundcovers underneath.  You will be providing habitat for endangered native bees, butterflies, birds and reptiles as well as building carbon storage. 

Now is the time to start your peppers, onions, leeks, tomatoes, tomatillos, and eggplants from seed to set out in May.  Wait until late April/early May to start squash, pumpkins, watermelons, canteloupes, etc.   If you plan to set out cauliflower, cabbage, kale, broccoli or other cole crops in mid-to late April, start them from seed inside now also.   A soil free organic seedling mix can be made from: 3 parts peat, 2 parts vermiculite, and 1 part perlite.  Heat mats placed under flats will aid germination of crops that like warm temperatures, such as peppers and tomatoes.   An east facing window is satisfactory, or fluorescent lights hung a few (8 to 10 inches) inches above the flats. 

Soon containerized fruit trees, shrubs, roses, bulbs, perennials, plus annual flowers and vegetables will be available in your local organic garden shops.  This year, I have grown several varieties of Certified Organic shrub roses on their own roots, found on old homesteads here in the Mission Valley:

‘Great Western’, a Hybrid Bourbon shrub rose is a long-time favorite in our area.  This rose was introduced in 1838, named after one of the first transatlantic steam ships.  It blooms for about three weeks in late spring/early summer. The plant is tall and wide, about 6 feet tall and 5 feet wide.   The flowers are fully double; a blend of rich reds and purples, with wonderful fragrance.  My grandmother grew this rose and there are plants at the museum in Ronan.  ‘Great Western’ is a hardy, easy to grow shrub rose.  The plant spreads slowly. 

‘Laure’, a Centifolia rose from 1837, was found in Ronan, at an old home built in 1913.  It is a rather short plant, with fully double, fragrant, powder pink blooms.  It is also a once bloomer, with a flowering period lasting about 3 weeks in late spring/early summer.  The plant spreads once established, but this is an advantage if your garden has an abundance of voles.  When a young plant is put in, a vole cage could be placed around the roots, but the plant will eventually spread outward and in later years a plant with an abundance of root stems will survive vole trails.  

‘Double White Scotch Rose’ introduced in 1808, is another locally found variety.  It has pure white, double, fragrant flowers in late spring.  It is of the same rose family as ‘Harison’s yellow’ the popular, thorny, hardy yellow shrub rose.  ‘Double white is equally hardy and trouble free, and spreads on its own roots to form a beautiful large group of plants.  I have seen established plants about 7 feet tall and spreading to about 8 or 10 feet wide.

Have a great spring!

 

GROWING ORGANIC KOHLRABI

Standard

IMG_0862

GROWING ORGANIC KOHLRABI

Kohlrabi is a delicious vegetable that is easy to grow in the intermountain climate, yet it is  relatively unknown.  It is a form of cabbage, in the mustard family, the Brassicaceae.   It is botanically classified as Brassica oleracea var. gongylodes.   Kohlrabi is more well-known in Europe and Asia than in the U.S. and well deserves better recognition and use here.  This vegetable takes less space than other cabbage family member, is easy to grow and it is more tolerant of heat.   Insect infestations do not directly affect the most desirable part of the plant, the swollen stem.  Yes, the sweetest, juiciest part of the plant is its stem, which swells with moisture and goodness as the plant grows.  The leaves are edible also, and can be used like cabbage, but the spherical stem can be peeled and cut into cubes; or shredded; or sliced to eat fresh alone or in salads.   The stem is also good cooked and can be used in casseroles and soups. 

Several varieties of kohlrabi are available today, several of them open-pollinated heirloom types.  ‘Early White Vienna’ (55 days) has been grown since the 1850s and is probably the most popular one in gardens.  Early Purple Vienna’ (60 days) from before 1860, is a purple variant of the white.  Both types are remarkably heat and cold hardy for Brassicas.  ‘Superschmeltz’ (65 days) is a giant kind of kohlrabi with stems weighing up to 10 pounds.  This last variety can be left in the garden longer than the other two as it does not tend to become “woody”.  Consistent watering will improve the sweetness and tenderness of this vegetable.  Mulching kohlrabi with 3 or 4 inches of rotted straw will preserve moisture in the soil and will enable you to have great results with less watering, while keeping soil microbes alive.   It is noteworthy that mulched soils are living soils, with abundant soil fungi and microbes that can capture carbon out of the atmosphere.   Keep in mind that bare, un-mulched soils dry and erode, and actually release carbon rather than capture it. 

Organic production of kohlrabi is not difficult.  If you end up with an abundance of cabbage loopers and aphids, the swollen stem will be peeled and so is less affected visually by insects.  However, production will be much higher if you place row covers with breathable insect fabric over your crop and mulch heavily.   Your other Brassicas will benefit from this technique also—there will be no holes in cabbage leaves or worms in the cauliflower and broccoli.   BT, or Thuricide  (Bacillus thuringensis) can be used, but it is better for the environment to simply cover all crops rather than spray.  Insects develop resistance to BT over a few generations, so it should  be reserved for use in special circumstances.  

In Western Montana, we direct sow kohlrabi out April 21-May 1 depending on weather, for harvest in July-early August.   Plants can be started inside about March 1 to be set out around April 15, and harvest would begin in late June.  A second crop (in the same space in the garden) could be direct-seeded around July 15-Aug. 1 following the first crop’s harvests.  Some gardeners plant a new row of kohlrabi every three weeks all season long.  It is ok to plant in the same space within one season, but remember to rotate your crops year to year.  Do not plant the any members of the cabbage family in the same place they grew the previous year; in fact for the previous three years.  A four-year rotation of vegetable crops in your garden will feed your soil and reduce insect and disease infestations.

The germination temperature for kohlrabi is 40-100 degrees F. with 45-95 F. being ideal.  Germination time is usually 3-10 days.  In my experience the percentage of seeds of kohlrabi that sprout is usually low, so plant extra seed in pans or outside when seeding direct.   Water regularly, steadily, and evenly; keep moist, not wet.  Be sure to thin the plants if you direct seed, and mulch when they are about three inches high.  Pests include gophers, root maggots, aphids, cabbage worms, cabbage loopers, diamond back moths, and flea beetles.  Diseases that can appear are: clubroot, alternaria blight, blackleg, black rot, downy mildew, fusarium wilt and wirestem.  It has been shown that soils with a higher pH will reduce the chances of some diseases.  The best soil pH for Brassicas is 6.0-7.5.   Kohlrabi grows best in cool summers, but we still had a great crop last year, which was during the hottest summer any of us remember here in Western Montana. 

 

 

 

GROWING SWEET AND HOT PEPPERS ORGANICALLY

Standard

IMG_1055

ABOVE: A PICTURE OF ‘CAYENNE LONG SLIM’ HOT PEPPER

GROWING SWEET AND HOT PEPPERS ORGANICALLY

Peppers are one of the garden crops that must be started inside and transplanted out to the garden later, when weather has warmed.  Years ago, people grew more sweet peppers than hot, but now hot peppers are very popular here in the northern Rocky Mountain and plains region.  I will discuss some pointers on how to start and grow your plants organically and I will include some information on the many varieties available today. 

Peppers (Capsicum annuum) prefer warm days and nights to grow and produce well.  In our mountainous area, with a short growing season and cool nights, peppers benefit from protection from cold early and late in the season.  So, we time our planting for after the last frost (usually around May 15 here at 3,000 feet altitude) and find it beneficial to cover our plants for the night until temperatures warm.  Row covers, hot caps, even cardboard boxes will collect heat from the soil and release it during the night.  The warm conditions promote faster growth.  Organically enriched soil and the use of organic fertilizers will also speed up growth. 

Hot peppers take longer to germinate than sweet peppers.  Seeds of both types will germinate between 60-95 degrees, but 80-85 degrees is ideal.  The germ time for sweet peppers is 7-14 days; for hot peppers, 14-28 days.  Here, we usually start our plants in February.  A mix of peat, vermiculite and perlite makes a great seed starting mix, as it is sterile (no soil-borne diseases).  Peat pots are great for starting seeds as they can be planted right into the ground when plants are large enough.  A solid flat with a dome cover will keep the seeds moist until they sprout.  Pepper seeds do not need light to germinate, but lights over the plants will promote sturdy growth and prevent spindly, “leggy” growth.  If you do not have lights, put the plants in a warm spot in a south window as soon as they sprout. 

Nights should be 55 degrees or above before planting out into the garden.  (If you are at a high elevation, use row covers.)  Make sure to harden plants off before planting, by putting them outside for a few hours at a time (in shade).  Gradually give the plants more time outside and brighter light for about a week of time.  When you are sure weather has stabilized, plant them out.  If they are in peat pots, make sure the peat pots are very damp and plant the peppers deeper, with about 2 inches of soil over the pots, so they will degrade.   If not covered, peat pots tend to dry out and a plant cannot pierce the pot with its roots.  Protect your plants from cutworms with jugs or cans or paper rings.  Water regularly, keeping them moist, not wet.  Water early in the day only; allowing leaves to dry early in the day.  Watch for aphids, their worst pest.  A preventative spray of Garlic Barrier will deter aphids.  Follow directions and use garlic sprays very early in the day, so as to not interfere with the activities of bees and other beneficial insects.  You will only need to spray garlic three times in a whole season.  A foliar spray of liquid organic fertilizer, such as Neptune’s Harvest Fish fertilizer will greatly increase the size and productivity of your plants.  This type of fertilizer is very low in salts, an important feature.  Worm castings will increase nitrogen levels in your soil and silica will strengthen stems. 

Insulating row covers (protection blankets) are very useful to extend our season for about 3-4 weeks.  These are more effective at lower temperatures than using poly film.   Mulch your peppers after soil is warm— June or early July, with red plastic or 2” organic straw.  Trim off all flowers until June 22, to enable plants to produce more heavily; otherwise, plants put all their energy into ripening an early crop and seasonal production is much lower. 

Here in the Mission Valley we put our peppers out about May 21-June 1 as weather permits.  Plant peppers about 14” apart.  Plant in full sun.  The growing temperature range for peppers is 55–85 degrees, with 75-80 being ideal.  Optimum soil pH is 5.5-7.0.  Peppers like even steady moisture—not wet soil conditions.  Try to practice regular, even watering; early in the day.

Pests of peppers include: gophers; leafhoppers; cutworms, leaf miners, hornworms, Colorado potato beetles, flea beetles, pepper weevils, mites, nematodes and aphids.  Diseases include: early blight, southern blight, anthracnose, bacterial spot and verticillium wilt. 

Harvest peppers when full size, 4-5 weeks from pollination + 4-5 weeks to ripen (about 9-10 weeks).  If the summer is cool, more time will be needed.  Harvest by cutting the fruit from the plant.  Check/pick every 3 days.  The first peppers should be ready about September 1 or earlier.  After harvesting keep cool, above 55 degrees, in high humidity and out of the sun.  Harvested fruit last about 7 days when stored out of the sun. 

Varieties (all open-pollinated, so seed can be saved each season):

‘King of the North’ heirloom sweet pepper (57 days to green, 65 days to red).   An early variety, grown for seed in the Mission Valley.  Fruit are 3-4” and production is good in our cool climate.

‘California Wonder’ heirloom sweet pepper (65 days to green, 75 days to red).  Another popular variety here, maturing a little later than ‘King of the North’, but more productive with larger fruit. 

‘Golden Cal. Wonder’ heirloom sweet pepper (60 days to green, 75 days to golden yellow).  A good, sweet variety for cool seasons, with large, 4” fruit. 

‘Purple Beauty’ sweet pepper (55 days to purple, 75 days to red).  A very productive, early variety with 3-4” fruit.

‘Chocolate Bell’ sweet pepper (70 days to green, 75 days to brown).  An interesting, early pepper that matures well and is grown for seed here in the Mission Valley. 

‘Jimmy Nardello’ heirloom sweet pepper (75 days to red).  A popular, 6-9” long, thin-skinned sweet pepper great for frying or drying.

‘Anaheim’ heirloom mildly-hot pepper (80 days to red).  The best pepper for stuffing.  An 8 inch long, thick-walled pepper that can be roasted, fresh dried, canned or stuffed and baked. 

‘Tesuque Chili’, Estacano Chili’, ‘San Felipe Chili’ heirloom chili peppers (about 70 days to red).  These three chili peppers are from Native American Pueblos in the Southwest.  They all are thin-walled, and excellent for drying.  They are excellent to use dried, ground up and added to dishes.  

‘Early Jalapeno’ heirloom hot pepper (60 days ).  The most popular hot pepper, used fresh and pickled.

‘Cayenne Long Slim’ heirloom hot pepper (70 days to red).  This pepper grows to about 6 or 7 inches long, is quite hot, and dries well.  Plants are very productive and early. 

‘Viet Hot Chili’ (95 days to red).  A very hot pepper grown locally (Mission Valley, Montana) for seed.  Plants must be started earlier than other peppers as they sprout slowly and mature slowly.   The fruit dry well.

‘Habanero’ heirloom chili pepper (95 days to red).   One of the hottest peppers available, it requires a long season, but is tops for flavor. 

 

 

ORGANIC GARDENING CAN REDUCE CARBON EMISSIONS

Standard

Montana Native Wildflower Mix

THE LOW CARBON FOOTPRINT OF ORGANIC GARDENING

 

We have all heard about rising carbon dioxide gas (CO2) levels in the earth’s atmosphere, which is causing heating, resulting in world-wide climate change.  The atmosphere holds about 800 billion tons of carbon at present.  Another 560 billion tons of carbon is stored in living plant life.  However, the soils of the earth hold the most carbon, about 2,500 billion tons!  Forest and grassland soils contain the most carbon, and soils degraded by chemically-drenched agricultural practices hold the least.  Rainforest soils can contain as much as 10% carbon of total mass, while the poorest and exploited soils have been reduced to as little as 1% of mass.  The process of photosynthesis by plants pulls CO2 out of the air and stores it in living tissues, excess carbon is released through the roots into the soil where it is stored.  This process is known as carbon sequestration.  Plant roots use living soil fungi (mycorrhizae) in the process.  Degraded soils have reduced numbers of these fungi, slowing their ability to sequester carbon.

It is estimated that the world’s agricultural soils have lost 50-70% of their original carbon. Most of that carbon has become CO2 and was released into the earth’s atmosphere.   If that carbon could be returned to the earth’s soils, the carbon in the atmosphere could be reduced enough to mitigate global warming and limit heating to 1.5 degrees Celsius.  We could do this by changing to organic gardening and farming practices. 

Gardening and farming practices that degrade soil are: fallowing, stubble burning, frequent tilling, overgrazing, monoculture cropping and excess application of synthetic fertilizers.  All of these reduce the soil’s carbon-holding capacity, soils dry and erode, and CO2 is released into the atmosphere.   

Organic gardening practices build living, healthy soils able to sequester much higher levels of carbon.   Farming trials in several countries around the globe have shown a rapid increase in carbon in soils where organic gardening and farming methods were employed.  A key to this is increasing organic matter in the soil. 

Methods known to restore soil’s ability to process and store carbon include: tilling as little as possible or not tilling, mulching, using cover crops, management of crop residues, crop rotation, and proper irrigation. 

If you are preparing a new garden space, place a heavy mulch of rotted, damp straw and compost or manure (or bedding from livestock stalls) onto the space for your garden plot.  This will smother existing plants and is best done in fall to be left in place all winter.  In spring, till the garden space, turning the straw and manure under.  This should be the only time you will need to till the soil.  Plant your garden crops immediately, and any areas to be planted later can be seeded to a cover crop.  A thick cover crop will smother weeds and will pull carbon from the air while it builds your soil. 

Rotate your garden or field crops in a four-year (or more) rotation.  (Each kind of plant is grown in a location in the garden or field once every four years.)  This will discourage pests and diseases.  Mulch your garden; this keeps soil animals alive and keeps soils moist and cool.  (Heated or dried soils lose carbon.)   As you weed, either compost the weeds or incorporate them into your soil.  The best time to add manures or compost is in spring or fall.

Plant shelter belts or hedgerows near or around your garden.  These will become homes for pollinators, birds, snakes and other animals beneficial to your garden.  Forests, hedgerows and grasslands hold the most carbon on the planet, so hedgerows and shelter belts help reduce emissions.   

Do not overgraze or till grasslands, because that will reduce the carbon-holding capacity. 

In flower beds and borders, prepare your soil the same way as for vegetables and plant perennial ground covers to act as living mulches.  In low-water landscapes, sedums or creeping yarrow planted between larger plants will act as living mulches.   

Changing to the regenerative methods of organic gardening and farming will result in lower CO2 emissions, healthy foods, heathy wildlife, clean air and clean water.

GROWING FRESH VEGETABLE SPROUTS

Standard

Sprouts

 

You can grow fresh, nutritious, organic vegetables right in your kitchen any time of year!   Nutritious sprouts can be grown from seeds in 3-6 days.  Germination releases a variety of nutrients, enzymes and proteins that makes sprouts easier to digest than dry seeds.  Sprouting increases the amount and bio-availability of proteins, vitamins and minerals.  Sprouts are high in protein, low in fat, high in fiber and loaded with vitamins. 

Sprouts are more concentrated in food value than fully grown vegetables, but most people add them to foods rather than eating them alone.  You can use fresh sprouts to finish a salad, or put them in a sandwich.  Sandwich fillings can be made by grinding sprouts to a paste.   Sprouts also make healthy, flavorful additions to stir fry dishes, soups and casseroles.  Some more popular uses are as additions to dips or fresh juices.  Sprouts can be added to pancake batter or scrambled eggs, too. 

To sprout seeds at home, purchase organically grown seeds labeled for sprouting.  This will be the cleanest, safest seeds you can use.  Start with small amounts of seed.  Try a tablespoon or two, or up to ½ cup if you are sprouting larger seeds, such as mung beans or peas.  Room temperature (65 to 75 degrees) is perfect for sprouting.  The rinse water should be about the same temperature.  Place the seeds in a wide mouth quart glass jar and then wash (rinse) them thoroughly with clean water.  A special sprouting jar lid will work well to drain the seeds, or cheesecloth fastened with a rubber band can be used.  Fill the jar with 2 cups of water and soak the rinsed seeds for 8 hours, or overnight.  In the morning, drain the seeds and rinse them again, twice.  Place the jar upside down, at an angle inside a clean bowl to finish draining for a few minutes.  Place the jar right side up again and place it out of direct sunlight, but not in total darkness (some seeds need light to germinate).   Rinse the seeds at least twice a day for the sweetest, freshest taste.  

When to harvest varies with the kind of sprout grown.  Most are ready in 3 to 4 days, but some take longer (mung beans take about 6 days).  Experiment with tasting the sprouts to see what size you prefer.  Usually they taste sweetest when tails emerge.  After harvest, store sprouts in covered containers in the refrigerator.  Fresh sprouts will last about a week in the refrigerator. 

You may have heard of problems with commercially grown sprouts that made people sick.  As long as you use clean jars and lids and rinse the sprouts at least twice a day there is little chance of a problem.  Remember to wash your hands after handling raw meat, and before touching fresh sprouts or any raw, uncooked food, as you prepare a meal. 

Some favorite sprouting seeds are: alfalfa, which is a cancer preventative loaded with vitamins A, B, C, D, E, F and K; mung beans, loaded with protein, fiber and vitamins A, B, C, and E, plus trace elements; peas, with vitamins A, B, C and E, and trace elements.  Broccoli, cabbage, mustard, arugula and radishes are all excellent and nutritious.  Several blends of sprouting seeds are now available.  They are packed with vitamins, minerals, proteins and fiber.

OCTOBER GARDENING CALENDAR

Standard

Hidatsa squash

 

Fall started all of a sudden this year!  Now is the time to bring in any remaining vegetables to ripen, or cover them with a row cover designed to take frosts into the mid-20s.  Plant bulbs, wildflower mixes and hardy annuals.  Harvest apples and pears, and sow seeds of hardy trees and shrubs. 

With row covers and cold frames as protection crops can still be harvested into November.  Ventilate plants in frames and give air and water freely.  When it is cold, cover with mats or straw and do not let the sun shine on an open frame full of frozen plants.   

Finish digging potatoes early in the month in case we get a heavy frost. 

Harvest Brussels sprouts, cauliflower, cabbage, carrots, lettuce, spinach and herbs.  Harvest and store cabbages late in the month: turn them upside down to dry, take off extra leaves and place them in a bin of sand in a cellar.  Or, place the cabbages in a trench filled with sand, cover them with more sand and place a water-proof cover (open at both ends) over the trench to keep them dry.  Close the ends with straw when frosty.  Thin spinach and lettuce planted last month.  If you have protected your pepper plants from frosts and heavy frost is on the way, pull up the plants and hang them upside down to ripen fruits.  Harvest ripe squash and pumpkins, leaving a one to one and a half inch stem.  Dig, divide and transplant garlic and shallots.  Hang onions to dry in an airy cool place.  Cut asparagus and perennial herbs back before winter.  Carrots may be left in the ground and covered with two feet of straw, leaves or peat moss to pick as needed most of the winter.   To prevent voles, cover the carrot bed with hardware cloth before you place the straw. 

Plant bulbs this month, finishing by November 15; give a top dressing of bone meal to the previous season’s bulbs beds.  Divide and replant peonies and plant wildflower seed. 

Divide perennials late in the month, after cool weather begins, into November.  Sow seeds of late-blooming perennials (to sprout in spring).  Trim lavenders and other shrubby herbs to a few inches and give them a light dressing of manure. 

If not already done, dig tuberoses, dahlias, amaryllis, gladioli and other tender bulbs.  Spread them out to dry in a warm room, clean off hair roots and decaying foliage and pack them up in dry boxes of sawdust.  Keep your bulbs in a cool, dark, dry, frost-free location.  Weed established bulb beds and spread bone meal as a top dressing. 

Harvest apples and pears for storage when the trees are dry.   To test for ripeness gently twist fruit gently one way or the other.  If it comes off easily it is ready to pick.  Place harvested fruit in heaps in a shed to dry further for 10 to 14 days.  Examine each fruit for bruises, which will cause rot in storage.  Wipe each one dry, wrap in paper and store in barrels; or, wipe dry and place in dry sand in the barrels.  Keep in a cool, dry cellar away from frost. 

Transplant trees, shrubs and fruit trees late in month. 

Watch for leafhoppers on roses and spray before severe frosts occur to get last generation before winter.  To protect tender roses over the winter, mound each plant with soil about 6 inches deep and place a layer of evergreen branches over that.  In the spring the soil can be removed gradually, about an inch at a time.  In the spring, uncover the plants gradually.  Use a gentle jet of water from a hose once a week or so, finishing about May 20.   If a heavy late frost threatens, place the evergreens over the crown of the plant again, removing them when weather warms. 

 

 

2017 SEPTEMBER GARDENING

Standard

IMG_5334

We have had a very hot summer this year so watch for spider mites on your garden plants, especially those in hot, dry locations.   If you have kept your house plants outside, inspect them carefully before you bring them into the house.  Check for any sign of insects or diseases and if you find any, treat with organic pest controls.  Watch for slugs and cultivate to expose and destroy grasshopper eggs.  Also, watch for corn earworms. 

Another important pest in Western Montana gardens are voles.  Wrap your fruit trees for winter with plastic tree guards so that these rodents will not strip the bark.  An effective method to protect the root ball of trees from being dug into and eaten, is to plant them using wire baskets over the roots.  Voles cannot chew through hardware cloth or into the new vole wire cages.  Caging is a safe-for-the–planet method that works for fruit trees, roses, shrubs, perennials and bulbs.  Be sure to cover the surface of the ground inside the basket edge so rodents cannot burrow down from the top.

Harvest peas, beans and cucumbers consistently in September to keep them producing.   Late in the month remove blossoms from eggplant, peppers, melons and squash in order to direct energy into to ripening remaining fruits.  Cover sunflowers from birds and pinch tomato tips.  Cultivate or hoe around cabbage, cauliflower, broccoli, turnips and celery.  Keep late maturing cauliflower and broccoli well-watered.  Plant garlic and shallots and over-wintering onion sets.  You can still direct seed a few plants for fall/winter greens: arugula, lettuce, radishes, cress, corn salad, chervil and kale. 

If you plan to grow crops under tunnels or in a cold greenhouse over the winter, plant seed (early in the month) of crops for winter use: chervil, kale, spinach, lettuce, radishes, corn salad, and winter cress.  Later in the month, from the 20th to the first week of October, plant seeds of cabbage, cauliflower and other brassicas for transplanting out into tunnels in October.  Have winter covers ready by October 1. 

September is a good time to make new beds for growing mushrooms.  Well-rotted horse manure is excellent. 

Gather ripe seeds of any vegetables (or flowers) you want to save seed from.

Prepare beds for planting bulbs.  Sow seeds of bulbous flowers collected in summer.  Transplant peonies and lilies and dig dahlias after killing frost.  Transplant pinks and carnations (with root ball intact) late in the month and plant out any other perennials and biennials where they are to bloom.  Most perennials can be divided now and replanted where they are to bloom. 

Gather ripe fruit from apples and pears.  Remove diseased fruits and “mummies”, rake up leaves under fruit trees and destroy them (to prevent apple scab).  Prepare equipment to make cider. Prepare beds for planting fruit trees, using well-rotted manure, digging down 18 inches.  Keep strawberries free of weeds and the soil moist.  If you plan to force strawberries in winter, now is the time to take them up and pot them.  Cut a root ball out with a knife, trim off dead leaves and runners and pot into 7 or 8 inch pots.  Place them in shade and water well.  Then plunge the pots in earth up to the rim.  Take them up and into frames or greenhouse before cold weather. 

Protect ripening grapes from birds with netting or gauze; keep weeds away from plants.  If wasps are a problem, hang containers of sugar water to catch them. 

Trim branches of evergreens and walnut trees, so wounds will heal before winter.  Keep weeds cleaned out from nursery beds and plantings of young trees.  Lay down grass turf this month or plant lawn seed. 

September is an excellent time to apply an organic from of potash to your garden plants to strengthen stems and roots in order to ripen them before winter.  Kelp meal can be applied as a surface dressing and watered in or you can do a foliar spray of seaweed twice during the month of September.  Do not apply nitrogen this month as it forces growth that will surely be winter killed.

 

 

AUGUST GARDENING CALENDAR

AUGUST GARDENING CALENDAR

GENERAL

August is often dry and hot, so be sure to water your crops and ornamentals that need irrigation to produce, especially those that must not dry out (primroses, chrysanthemums, etc.).  Pay attention to the timing of harvesting vegetables and cut flowers.  Harvest and dry herbs also.  Collect seed from perennials, shrubs, trees to plant; gather flowers and pods to dry.  Prepare soil and beds for planting lawns, fall bulbs, perennials and roses using organic amendments.   Be sure to bring in house plants when night temperatures drop below 45 degrees.  Apply potash in the form of kelp meal or alfalfa meal mid-month to harden trees and shrubs for winter.  Stop watering garlic, storage onions and shallots in late July or about August first.  The bulbs will need to dry off in the ground for two weeks before digging.  Slow down watering of ripening potatoes when foliage dries.  For long-season winter squashes, pumpkins or melons Pinch off female flowers to hasten ripening before frosts of those set on the vines. 

VEGETABLES

During the first week of August, direct sow spinach, radishes, turnips, peas and lettuce.  In cold frames, greenhouse or under tunnels, sow cabbage and cauliflower for late fall/winter frame crops. 

Other crops that can be sown  and grown on inside a frame or tunnel for extended harvest into winter include: beets, cabbage, Chinese cabbage, chicory, dandelion, kohlrabi, lettuce, mizuna, tatsoi, onions, onion sets, parsley, parsnips, radishes, sorrel, and turnips. 

When harvesting cabbage, cut heads above the bottom leaves at a steep angle to avoid rain or irrigation water rot.  After new cabbage buds appear, thin to 3-4 per plant for a crop of mini cabbages.  Cabbage can be prevented from cracking by withholding water and root pruning on one side or twisting the head ¼ turn.

Harvest onions, garlic and shallots.  Dry them on screens in a shed or garage.  Hang dried bulbs in net or jute bags to keep them dry.  

FLOWERS

This month, direct sow seeds of biennials and early blooming perennials.  Sow bulb seeds.  Transplant seedling perennials out into nursery beds.   Direct sow pansy seed in place for next summer.  Cut back violas selected for division.  Encourage and peg down runners to replace mature violet plants.  Prepare frames to over winter violets to bloom in winter. 

Repot auricula primroses in first week of August; take of offsets and pot up.  Sow fresh auricula seed now, saving half for January/February.  

FRUIT

Tie paper bags loosely over grape clusters to protect from birds. 

TREES, SHRUBS AND ROSES

Do not give any nitrogen to your shrubs, roses and trees as that will cause late soft growth easily damaged by frosts.  It is helpful to apply potash instead, as described above.  In August you can plant lawn seed.  Make sure your soil is raked smooth and roll or stamp the seed in so it will not blow away.  A light mulch of dry grass clippings or pine needles will protect the seed until it germinates.  Water the seeded area three or four times a day for a few minutes each time to keep soil moist.  Usually, grass seed comes up within 10 days.
