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. 

GROWING LETTUCE

Standard

Lettuce 'Jericho'

GROWING LETTUCE

Lettuce is one crop we can grow here in Montana over a longer season than most vegetables.  Lettuce and many greens can be direct-seeded as early as March 21, even though the soil is still cool.  The minimum germination temperature for lettuce is about 35 degrees F. and 66 degrees F. is ideal.  A cold frame or tunnel placed over the seedbed will warm the soil and hasten germination, especially if it is in a sunny spot.  After planting, lettuce will be ready to cut in about three or four weeks.  Sow lettuce in succession, every two weeks or so, to provide a continuous harvest all season.  Lettuce prefers cooler weather and will turn bitter and bolt early if it is hot.  In hotter weather, plant successive crops about 10 days apart to ensure a constant supply.  Later, in cooler fall weather, stretch out the days a bit.  Lettuce can be sown as late as October 20th.  Use a poly tunnel or cold frame to protect late sowings from hard frosts.  In a cold frame, lettuce can be harvested quite late in the year.  A few varieties that tolerate colder weather and frosts include: ‘Merveille de Quatre Saisons’ an old French heirloom; ‘Red Oakleaf’; ‘Rouge d’Hiver’; ‘Valdor’ and ‘Valmain’. 

Sow lettuce at the rate of 60 seeds per foot in a 3” wide band in rows 12” apart .  Cover seed only 1/8” deep and firm gently.  Full sun is the best spot for lettuce.  Growing temperatures for lettuce range from 45 to 75 degrees F. with 60-65 degrees being ideal.   There are types of lettuce that tolerate warm weather better than others.  These varieties include: ‘Black-Seeded Simpson’; ‘Deer’s Tongue’; ‘Jericho’; and ‘Oakleaf’.  Your plants will grow best in cool days with cool nights.

The best soil pH for lettuce is about 6.0-7.5.  Since the plants have rather weak root systems, it is best if your soil is rich and moist.  Germination time varies from 2-15 days.   In the spring season, protect from cutworms with cardboard collars, or two layers of newspaper, or a layer of aluminum foil.   Water regularly; keep moist but not wet.  Water early in the day only, allowing leaves to dry before evening.  Regular watering is excellent, but do not allow soil to become saturated for long periods.  Lettuce does best with steady, even watering, especially in summer.

Pests on lettuce (besides cutworms) include: gophers, tarnished plant bugs, thrips, aphids, leaf miners, flea beetles, slugs, mites and nematodes.  One way to minimize pests is by growing your crop under insect fabric stretched over row covers.  Some diseases of lettuce are: early blight, verticillium wilt, mosaic, yellows and rust, but these are usually not troublesome here in Montana. 

Cut lettuce early in the morning with scissors, cutting only as much as you need for a day or two.  Try to keep it clean as you cut.  When ready to use, wash carefully.  After washing/drying make sure the leaves are not too wet when they are put into bags.  Stuff the bags loosely with the lettuce.  A person may add edible flowers of nasturtiums, pansies, or calendulas to a mix of greens to brighten up the look of a salad.  Keep cut lettuce as cool as possible to prevent wilting (45- 55 degrees, in high humidity and out of the sun).

GROWING EGGPLANT

Standard

Eggplant New York Improved

GROWING EGGPLANT

Eggplant is not often grown by home gardeners in Western Montana, but a good crop can be harvested and seed saved for next year if you give it what it needs.  Eggplant is native to warm, subtropical regions in India and China where it has been cultivated for more than 6,000 years.  The botanical name of the species is Solanum melongena and it is a member of the plant family Solonaceae , which means it is related to tomatoes, peppers, potatoes and petunias.  I grow eggplant in my USDA Certified Organic garden in the same rotation group as these relatives.  (It is important to rotate your garden crops in family groups so that they are not planted in the same spot for four years or more.  This builds soil and reduces risks of disease and insects.) 

Since eggplant starts growing rather slowly, it should be started inside and transplanted out to the garden later, after danger of frost is past.  I start mine inside under lights about February 1, and grow them on in bright light.  Here in the Mission Valley, our average last frost in spring is about May 17th or so, but of course this can vary by a couple weeks each way in any given year.  Eggplant seed will germinate from 60-95 degrees F., but 75-90 ideal.  The time to germination is 14-21 days.  

Harden off your plants before setting out, giving them more and more time outside each day and more sun, for about a week.  Plant them in full sun.  I usually transplant my started eggplants about May 21 to June 1, unless it is very cold and rainy.  Eggplants will grow well under hoop row covers with open ends, because they really like heat, especially at night.  Your soil pH should be 5.5 to 6.8 for best success.  Set plants about 18 inches apart all ways.  The plants grow best when temperatures are 50–95 degrees, and 70-75 degrees is ideal.   

Protect your young plants from cutworms with jugs or cans or paper rings.  Water your plants regularly, allowing them to get just sub-moist, then water.  In my experience they seem to prefer even moisture.  Try to water early in the day only, allowing leaves to dry before nightfall.  Watch for aphids, their worst pest.  You could use fabric over hoops during summer to prevent insects.  Some other pests that might bother eggplant include: gophers; leafhoppers; cutworms, Colorado potato beetles, flea beetles, mites, stink bugs, nematodes and tomato fruit worms.  Some diseases you might encounter are early blight, late blight, tobacco mosaic, fusarium, and verticillium wilt.  An application of garlic spray early in the season and followed again with the same once a month until autumn will discourage leafhoppers, which carry and continue into fall to prevent curly top. 

To harvest your eggplant, gather when full size, while skin is still shiny and when fruit comes away from the vine easily.  If the skin has turned dull, the seeds are ripening and it is too old, but of course an over-ripe fruit is worth saving for seed for next year).  Check and pick every three days to keep plants producing.  The first eggplants should be ready about September 1.  After harvesting keep the fruit cool, above 55 degrees, in high humidity, and out of the sun.  Fruits last about 7 days. 

A variety that has been successfully grown for seed here in our area is ‘Early Black’ eggplant.  It matures 65 days from transplanting out.  Another good variety is ‘New York Improved’, and heirloom American variety from 1865.  It will be ready to eat in about 75 days from transplanting. 

 

 

 

 

ORGANIC VEGETABLE GARDENING

ORGANIC VEGETABLE GARDENING

By James Sagmiller

The benefits of gardening organically are many.  First, food grown without dangerous pesticides and herbicides is safe for us and our children to eat.  Second, using organic methods protects our natural environment: soils are healthy, waters are protected from dangerous runoff, insects, birds, and water creatures are all unharmed by dangerous chemicals.  With organic methods, your soil becomes alive with organisms such as mycorrhizal fungi, which, through a symbiotic relationship with plant roots, increase a plant’s ability to uptake moisture and nutrients.  These fungi, along with beneficial soil bacteria, create an ideal, sustainable environment for crops—exactly the opposite of degraded soils exhausted through repeated use of chemical fertilizers. 

At first, planning to “go organic” might seem difficult, but I assure you the rewards are worth the time taken to learn easy ways of gardening organically.  Siting, fencing, and soil building are first steps.  Find a location for your garden that receives full sun, preferably one with wind protection.  If a site is windy, you can put lattice or privacy webbing on your fence to slow down the blast.  Shelter belt plantings of native trees and shrubs are excellent too.  Because deer are so prevalent nowadays, an 8-foot high fence is the best way to shield your garden.  Other methods are less effective.  I made my fence out of game fencing and 10-foot metal posts.  A 6-foot fence that hides what is on the other side will work also; if deer cannot see what is on the other side, they will not leap over.  Deer will eat anything if they are hungry enough! 

A soil test is very helpful before you begin your garden spot.  You can immediately see what nutrients you have in your soil and which ones you need to add more of.  It is also good to know the analysis of purchased soil amendments (marked with the letters N-P-K on fertilizer labels).   For high nitrogen contents (N on the label) choose blood meal, cottonseed meal, alfalfa meal, and composted manure.  Amendments with high phosphorous (P on the label) include fish bone meal and rock phosphate.  Potash (K on the label) is abundant in kelp meal, alfalfa meal and wood ashes.  Keep in mind wood ashes and bone meal become alkaline (higher pH) as they decompose, and cottonseed meal becomes more acidic (lower pH).  It is helpful to have a test kit and know your soil’s pH and NPK content.  Nitrogen promotes good green growth, phosphorous promotes flowering and fruiting, and potash encourages root growth and ripening of fruits and seeds.

To kill out grass and weeds for a new garden spot, use something safe that will shade the ground.  Some options are: landscape fabric with weights on it, newspaper covered with moist, heavy organic straw, or black plastic weighted down.  It takes a few weeks to kill out most plant material, but some perennial weeds will remain and seeds will sprout again.  If you are planning well ahead, you can immediately plant a soil-building cover crop to shade the soil until you plant vegetables.  If you need to start right away, till the soil, add organic amendments, plant your seeds and transplants, then mulch. 

When you plant seeds, choose organically certified seed if possible, especially for food plants.  Heirloom seed varieties, which are all open-pollinated, are excellent for organic gardening, because being generations-old, they are well-adapted to climates where they have been grown for a long time.  Heirlooms often ripen in succession rather than all at once, frequently are more nutritious, have exceptional taste, and seed can be saved from them to plant next year.  Another plus is that many heirloom varieties were developed to last well in storage—a valuable trait for local sustainability and for gardeners who want to be self-sufficient.

Mulching your garden is important to conserve moisture and provide for living soil organisms.  Landscape fabric, organic straw, compost, or composted grass clippings work well.  (Fresh grass clippings or other fresh greens will draw nitrogen out of the soil rather than add nitrogen.) 

Be sure to include a home for pollinators in or around your garden.  Native wildflowers are best; they will attract and foster native species of bees and other insects.  Another effective tactic is to release ladybugs, lacewings, praying mantises and other pest-eating bugs in your garden at proper times.  It is helpful to provide bird, bat houses and Mason bee houses.

Most gardeners new to organic gardening have anxiety about controlling pests and diseases.  Healthy, thriving plants, combined with preventative methods are the most effective ways to begin.  A diversity of crops will help confuse damaging insects (the scent of marigolds, for example confuses some pests).  Crop-rotation will prevent a host of pest and disease problems.  Plan your vegetable layout so that the same kind of plant is not grown in the same spot for at least 4 years.  Collars made from toilet paper rolls or plastic cups will deter cut worms.  Netting will prevent birds from eating strawberries.  Light insect fabric on row covers will protect all cole crops from cabbage loopers; and straw mulch around tomatoes will make a home for beetles, which will eat aphids off the tomatoes at night.  Garlic spray over your vegetables will confuse most damaging pests and prevent infestations if timed at monthly intervals.  Safe pesticides and fungicides, such as BT, horticultural oil, neem oil, insecticidal soap, pyrethrum, and diatomaceous earth are each effective for certain listed pests.  Always follow directions and precautions to the letter with any pesticides or herbicides. 

Take advantage of the latest technologies to assist your organic garden.  A few of these include: season-extending high or low tunnels, solar-powered heating and cooling, and frost-protection fabrics.  Using tunnels and row covers can improve yields significantly because you get a month to 6 weeks longer season of growing and harvesting!  Automatic solar vents for cold frames, greenhouses and high tunnels will save you labor and worry—especially in our volatile climate, with its ups and downs in temperature, alternating clouds and sunshine, and sudden winds that occur in a typical Montana spring.  Solar powered fans will kick on automatically when the temperature gets too high in a tunnel or greenhouse, and will not contribute to the overabundance of carbon dioxide in our atmosphere.  I wish you the best of luck and success in your organic gardening!

 

MARCH GARDENING CALENDAR

Standard

fullsizerender-19

MARCH GARDENING CALENDAR

March is a very busy month for Montana gardeners!  A brief summary of things we can do now is: plant lettuce and spinach in cold frames; plant/prune cane fruits, fruit trees, deciduous trees; plant evergreens as soon as ground thaws; plant rhubarb, strawberries, asparagus, sea kale, and artichokes; weed and clean borders, plant perennials, sow seeds of hardy annuals and biennials outside; sow seeds of tender annuals and vegetables inside.  Clean pansy beds and manure them; cover cold frames at night and admit air during the day. 

VEGETABLES

Late in the month, begin to harden off cool loving vegetables (from a January sowing) in frames.  Sow indoors: broccoli, cabbage, cauliflower, kale, kohlrabi, head lettuce, artichokes, Brussels sprouts, Asian cabbage, greens, peppers (finish peppers early in the month).  Start tomatoes also.  Late in the month direct-sow outdoors: asparagus, beets, arugula, carrots, celery, chervil, chives, cilantro, dill, fennel, collards, mache, fava beans, cress, kale, kohlrabi, leeks, lettuce, mustard greens, rhubarb, turnip greens, onions, parsley, peas, radishes, scallions, spinach and Swiss chard.  As soon as weather permits plant: asparagus roots, broccoli, cabbage, cauliflower, garlic, shallots, lettuce, onion sets and plants, horseradish, strawberries and Jerusalem artichokes.  Finish sowing herb seeds this month.

FLOWERS

Begin dividing perennials as soon as the ground is thawed.  Direct sow outdoors: annual alyssum, pinks, sweet Williams, stocks, rose campion, wall flowers, lychnis, lupines, lavateras, columbines, valerian, polyanthus, auriculas, Canterbury bells, cynoglossum, hollyhocks, honeysuckles, rockets, honesty, fox gloves, snapdragons, sweet peas, poppies, larkspur, cornflowers, nigella, lavatera, valerian, poppies, kiss-me-by-the-garden-gate and dill.

FRUIT

Fertilize (spread organics), plant and prune fruit trees, blackberries, raspberries, grapes, currants, blueberries.  Clean strawberry beds and make new beds.  Fertilize (spread organics) on strawberries and asparagus.  Clean up after pruning fruit trees; remove dead wood, dropped fruit, and inspect trunks for egg masses.   Spray Bordeaux mix on fruit trees that suffer from fire blight after carefully pruning out affected wood.  (Cut 6 inches below signs of infection, sterilizing pruning tools between cuts with alcohol, or a 10% bleach solution.)  Spray superior oil on dormant trees (before leaf out).  Wait three weeks after dormant spray if you decide to spray lime-sulfur (use caution) as a fungicide on roses, lilacs, dormant shrubs, fruit trees, evergreens. 

TREES, SHRUBS AND ROSES

Plant evergreens, roses and other shrubs during March.  This month is the very best time of the year to move or plant evergreens.  Wait until April to prune roses as canes often die back from late frosts if cut too early.  Dress with your roses Epsom salts now, and apply wood ashes, compost, manure, alfalfa meal, bone meal, kelp meal, and other organic amendments to rose, perennial, fruit and vegetable garden beds. 

A NOTE ON SEED

Now is a great time to test the germination on your stored vegetable seeds.  To establish a percentage of germination for your seed, place 10 seeds in a moist paper towel, lay it on a plate; with a loose cover of plastic wrap, or a glass or plastic dome.  Put the plate in a warm location and wait a few days.  The number of seeds that germinate will give you a rough idea of the percentage of live seed you have.  This kind of test is a good way to see if your old purchased seed, or seed that you have saved yourself, will grow. 

Now is also a prudent time to plan which varieties of vegetables you might want to save seed from for next year.  Once selected and growing, plan to save seed from your best plants.  Choose plants mid-season in their fruiting and mark them with tags or labels, as ones to save seed from.  Pick the fruits when past eating ripeness; clean the seed carefully.  Dry it well before storing in clean, dry glass jars with metal lids.  Label the jars carefully with variety name and year of harvest.  Store your seeds in a cool, dark, dry place so they have the best chance of staying alive.  Seed-saving techniques vary from species to species, so it is good to obtain as much information as you can before you try.  A great book is Saving Seeds by Montana authors Robert Gough and Cheryl Moore-Gough; another is The Heirloom Gardener by Carolyn Jabs.  An excellent book about seed starting, saving and plant propagation is: The Royal Horticultural Society Propagating Plants, Edited by Alan Toogood.  These three books may not be the newest, but their information is detailed and practical, especially the latter book.  An online article with basic information about seed-saving, including lots of pictures, can be found at: https://robinsonloveplants.com/saving-seeds/
