DECEMBER GARDENING CALENDAR

Standard

onion Southport Red

 

GENERAL

Check stored vegetables and fruit often; inventory seeds and test germination and order seed.  Keep perennials and bulbs growing next to the house covered with snow to insulate them from extreme cold.  Make sure all young fruit trees have their trunks wrapped and place wire netting around trunks to prevent damage from rabbits and voles.   Mulch hardy tree seedlings and bulb beds with pine or fir branches. 

Save wood ashes all winter long to spread on beds in spring on plants that enjoy alkaline soil conditions.  

VEGETABLES

Admit air to cold frames and cover frames at night.  Uncover on mild days, but do not let sun shine on frozen plants.  Pick off any decaying leaves.  Cover every night with mats, blankets, straw, ferns or insulating row fabric.  Late cabbages, kale and greens should be covered in hoops covered with row cover fabric. 

Check stored vegetables often: potatoes, onions, carrots, and cabbage, etc.  Also check stored flowers and fruit: dahlias, glads, cannas, apples, pears.  Cabbage likes high humidity (80-90%) and a storage temperature of about 35 degrees.  Potatoes, glads and dahlias prefer about 45 degrees and high humidity.  Onions and garlic need air, with about 60% humidity, so hang and keep them dry, storing at about 35 degrees.  Apples need about 30-35 degrees with high humidity. 

Force asparagus in hot beds. 

FLOWERS

If there is no snow, cover perennials and roses with evergreen branches to protect them.  Spread thin, flaky manure over pansies, carnations, pinks, tulips, penstemons, phloxes.  Spread composted manure over the vegetable garden.  Over the winter the manure will break down and feed the soil and any pathogens will be gone by the time you begin planting vegetables in mid-March.

For house plants: start amaryllis, watering lightly at first with warm water.  Keep in a warm place and gradually increase watering as the stems elongate, but do not keep the plants wet.  Moist soil is best.  Watch for spider mites on houseplants, mini roses and amaryllis.  If you see them, wash the whole plant first with plain water; then spray with insecticidal soap every 3 days for 2 weeks.  Do not overwater houseplants this time of year, especially geraniums, which are nearly or totally dormant now. 

Late in the month, after the 20th, start seeds of begonias, geraniums, primroses, Dahlias, pansies, and lisianthus. 

For potted auricula primroses and other plants, keep admitting air into the frames and keep frame covers handy if the weather gets very cold.  Cover outdoor primulas with light straw. 

FRUIT

Check stored fruit often for spoilage and discard any rotting fruits. 

TREES, SHRUBS AND ROSES

Take cuttings of lavender, pyracantha, sumac, spirea, mock orange, wiegela, wisteria, and robinia.  Place them in a mixture of ½ peat and ½ perlite.  Insert small stakes into the pot to act as supports.   Place plastic bags over the tops of the pots and sink them into sand or soil inside a cold frame situated in shade.  The cuttings should root over the winter.

DEER RESISTANT PLANTS FOR THE ROCKY MOUNTAINS AND NORTHERN PLAINS

Standard

deer

Mule and Whitetail deer are abundant these days over much of our region.  As many of us have experienced, deer can do a lot of damage to a garden in a short time.   In spring and summer they eat flowers and foliage.   In winter deer browse on the young shoots and buds of shrubs and trees.   Deer prefer some plants over others, but if they are starving, they will eat almost any plant.  Some of their first-choice favorites are tulips, roses, pansies, arborvitae and young fruit trees.

An eight foot (or higher) fence is the best protection for garden plants, but fences are not always practical or attractive in certain locations.  Some popular deer repellents are: human hair, dog hair, scented soaps, blood meal, egg yolks mixed with water, thiram fungicide, and sprinklers activated by movement.  Deer repellents are not always effective and usually have to be reapplied after rain.   Often, deer seem to get accustomed to a repellent’s odor and will eventually return to browsing the garden.  Strongly scented soaps worked for quite a while for me, but eventually the deer returned and I ended up with heaps of water-soaked bars of soap decorating my planting borders. 

Vegetable and fruit gardens probably need to be fenced in our area, but if you are growing ornamental plants only, why not choose deer-resistant species adapted to our climate?   That way you can have a beautiful garden deer will (for the most part) leave alone.  The term “deer-resistant” means that the species listed here are less preferred as food than other commonly grown garden plants.  These plants are often fragrant, or poisonous, or irritate a deer’s stomach, so are not as often eaten.  I have indicated the common name, species name and USDA coldest climate zone:

NOVEMBER GARDENING CALENDAR

Standard

cabbage-red-express

Cold winter weather does limit what we can do in the garden in November in our northern Rocky Mountain climate (USDA zones 3, 4 and 5).  If ground is still unfrozen, prepare beds for next spring’s early crops.   If you still have unfrozen manure or compost it can be spread over vegetable and flower beds and trenched into furrows to receive frost (this will break down over winter and lighten and feed the soil).  I have spread manure and compost right over the snow on planting beds and it worked just fine. 

Check over which varieties of flowers and vegetables you liked or disliked this year.  Make a note of which ones did well.  Keep your records up to date if you can.  Check stores of fruits and vegetables and discard spoiling ones.  Clean all your tools, oil wooden handles and replace cracked ones.  Drain gas and oil out of lawnmower for winter. 

Finish planting garlic, shallots, and Egyptian walking onions before the ground freezes solid.

Have row covers ready for remaining crops in the field; also have covers ready for cold frames.    Carefully store row covers before winter; make sure the fabric is dry before folding and storing. 

Early in the month, if not done earlier, harvest and store cabbages.  To store them, turn them upside down to dry, take off extra leaves and place them in a trench of sand and cover with a wet-proof cover open at both ends to keep them dry.  Close the ends of your cover with straw when frosty.  Also, to store beets, carrots, parsnips, turnips, salsify for winter: dry and cut the leafy tops off.  Dig a pit in a dry place if possible.  Put down 2 inches of sand, then the vegetable roots, then more sand, alternating.  Cover them with a final layer of sand and straw to protect them.

Admit air to cold frames and the greenhouse on sunny days; pick off any mildewed or moldy leaves.  Apply manure or compost to outdoor asparagus and rhubarb beds to 4 inches deep.  Weed onions, leeks, spinach, mache, cresses.  In frames, when it is cold, cover lettuces, cabbages, etc.  Harvest late and frame–grown cabbage, spinach, carrots, peas, cauliflower, lettuce, broccoli, Brussels sprouts.

If the ground has not frozen solid, finish dividing and replanting perennials before winter freeze-up.  Transplant seedling perennials and flowers into flats; keep them in a cold frame or cold greenhouse.  Mulch primroses, bleeding hearts, and any marginally hardy perennials with pine or fir branches.  Cut back established pansies and collect violet seed.   

Finish planting bulbs out and plant bulbs to be forced in pots.  Weed bulb beds and spread bone meal if not done last month.  Put poultry netting over the top of the soil of newly planted tulips, crocus and hyacinths to discourage squirrels and cats who like to dig and scratch into fresh soil.  Plant these same bulbs in Vole King wire baskets to protect from voles. 

In the greenhouse plants will be at rest.  Keep their foliage dry and do not overwater!  Succulent plants such as cacti may need little or no water all winter.  If mold appears, dust with sulfur.  Moving air inside a greenhouse discourages mold. 

If you plan to keep any plants in pots over the winter, plunge them up to their pot rims into a holding bed.  The reason for doing this is that plant roots suffer greatly from the wide temperature swings of air during winter.  Good substances for this are: fine gravel, bark, sand, sawdust or soil.  If you have any bulbs, perennials, roses or shrubs growing in pots outside, be sure to sink them up to the rims to protect them from cold over winter. 

Cover cold frames if it is frosty and cold.  If you vent the frame, make sure no direct sun hits plants while they are frozen. 

Weed fruiting shrubs, add manure to raspberry beds.  Finish storing apples, pears, etc.  Clean all leaves and mummy fruit around trees to prevent disease and discourage insects.  Sow seeds of fruit trees and rootstocks.    

Finish planting deciduous shrubs and trees.  Mound soil around the base of tender hybrid tea roses to a depth of about 10 to 12 inches.  Evergreen boughs may be placed over the soil mound.  The soil and boughs will protect the lower portion of tender rose plants over winter. 

 

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 OctoberHave 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

Standard

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).

JULY GARDENING CALENDAR FOR WESTERN MONTANA

Standard

FullSizeRender (16)

JULY GARDENING CALENDAR

Because July in often hot, water berries (they need constantly moist soil) as well as fruit trees and vegetables as needed.  After garlic, shallots and storage onions flag or look wilted, withhold water.  Carefully dig and cure them over wire (usually one week).  Decrease water to potatoes when tops begin to die back, though this will probably not happen until August this year.  Check for pests frequently (aphids, leafhoppers, squash bugs and leaf miners).  Weed squash, cucumbers, melons, pumpkins to increase production.   Clean and weed borders. 

VEGETABLES

Early in the month you can start some fall crops indoors to plant out in late August/early September: cauliflower, broccoli, Brussels sprouts, late cabbage, Chinese cabbage, bok choi and radicchio.  All of these are plants that grow and produce well in the cool fall weather.  Plant them out in 5 to 6 weeks, when they have two sets of leaves.  Cauliflower should be ready about 55-60 days from transplanting (October).  Have covers ready for severe frosts below 26 degrees F.  The time period of late June and early July is the best time to plant seeds for healthy fall crops.  You can also direct sow several vegetables all month long: lettuce, kohlrabi, dill, rutabagas, Swiss chard, carrots, collards, endive, fennel, kale, peas, and scallions (green onions).  

For extended harvest into winter, the gardener can grow vegetables in protected frames or tunnels.  If covers are large enough for extended growing, direct sow: beans, broccoli, carrots, cauliflower, celery, kale, rutabaga, salsify and New Zealand spinach.    

If you started seeds in June, you can transplant out leeks.  Plant them deeply and cut the tops shorter.  Cool weather crops including Brussels sprouts, cabbage, and cauliflower are best transplanted out late in July.  Shade them to protect them from transplanting shock and August heat with cardboard or a row cover or tunnel using fabric instead of polyfilm. 

At blossom time, fertilize your peppers with 4 tablespoons Epsom salts in one gallon of water and repeat 2 weeks later.  Fertilize established asparagus with rotted, composted manure and June-bearing strawberries after harvest.  Watch for corn earworms and powdery mildew.  Hill up potatoes to keep the tubers cool.  Transplant and divide iris and primulas. 

Harvest: lettuce, carrots, beets, onions, leeks, peas, cucumbers, tomatoes, squashes, bush beans. 

FLOWERS

Sow seeds (in frames) of early-blooming perennials: primroses, lupines, tulips, and poppies.   Biennials, such as sweet William, Canterbury bells, sweet rocket and stocks can be direct sown now and into August.  Sow winter pansies, but also collect pansy seed from the plants you like the best.  Remove lanky, exhausted growths to encourage short new stems from the center.  Take cuttings of pansies for autumn planting.  Remove violet runners, mulch them, feed them and keep foliage moist by frequently spraying with water.  Take up spring bulbs such as tulips, hyacinths, fritillaries, colchicums, autumn crocuses, etc., when leaves are decayed.  Carefully dig them and dry over wire screen.  Propagate from offsets and store in cool, dry place for the summer. 

FRUIT

Pick up fallen fruit; check for canker.  Propagate strawberries by runners and plant them into new beds. 

TREES, SHRUBS AND ROSES 

Finish trimming evergreens, box edgings and all types of hedges early in the month.  Prune spring blooming shrubs now.  Water lawns during hot weather to keep them green.  Prune old-fashioned once-blooming shrub roses now, after blooms fade, removing no more than 1/3 length of canes.  Trim out old, non-productive and dead wood.  Have a great July!

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.
