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. 

JULY GARDENING CALENDAR FOR WESTERN MONTANA

Standard

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!

 

MONTANA PLANTING CALENDAR FOR JUNE

JUNE GARDENING CALENDAR

Our pictures today are, from left to right: heirloom morning glory “Grandpa Ott’s”, and a seedling ivy geranium.  

This month you can transplant out tender vegetables, early in the month, after frosts.  If you have not planted your garden yet you can still purchase and transplant out tender vegetables that require a shorter season (80 days or fewer).  Cole crops, such as cauliflower and cabbage, and most every transplantable vegetable can be planted until about July 1, when you could begin to sow fall crops.  Fertilize and prune cantaloupes; watch for pests and diseases on garden plants.  Keep a watch on watering if weather is dry and hot; weed after watering as plants pull up easily. 

Vegetables you can direct sow until June 15 include: amaranth, dill, summer savory, edamame beans, chervil, early-maturing corn, NZ and Malabar spinach, carrots, cucumbers, parsnips and pole beans.  Sow successive crops all month of: lettuce, spinach, bush beans, beets, cabbages, cucumbers, onions, peas, radishes, potatoes. 

Transplant out leeks, endive, herbs, plus tender vegetables.  Some of these are: tomatoes, eggplant, peppers, cantaloupe, squash, pumpkins, watermelon.  Fertilize and prune cantaloupes; when they start to vine, foliar feed with 1 tablespoon borax + 1 tablespoon Epsom salts in 1 gallon of water.  Repeat when fruit is 1” to 2” in diameter.

Late in the month (for transplanting out for a fall crop) sow: Brussels sprouts, late variety cabbage, cauliflower, kohlrabi.  Transplant out in late August/early September (5-6 weeks, with two sets of leaves).  Grow cool, possibly under netting to prevent cabbage loopers.

Harvest: beet greens, cauliflower, cabbage, radishes, lettuce, turnip greens, onions, peas, rhubarb and asparagus.  Harvest herbs: mint, balm, lavender, sage, clary, rosemary, etc. for using fresh, drying or distilling; when just coming into flower.  Lay them in the shade or on a screen in a shed to dry. 

Direct sow tender annuals and half hardy annuals early in the month (before the 15th): zinnias, marigolds, cosmos, annual euphorbia, gypsophila, nasturtiums, scarlet runner beans, Scabiosa atropurpurea,  stocks, sunflowers.  Sow nigella (succession plant every 2 to 4 weeks until end of month). 

Finish transplanting perennial starts and annual starts.  Stake dahlias, delphiniums; mulch dahlias; check for slugs around auriculas, cannas, delphiniums, hollyhocks and hosta. 

Take up spring bulbs such as tulips, hyacinths, fritillaries, colchicums, autumn crocuses, etc., when leaves are decayed.  Carefully dig and dry them over a wire screen.  Propagate from offsets, store in cool, dry place for the summer. 

Plant strawberry runners into new beds.  Thin tree fruits after bloom so no fruit touches (this discourages codling moths); protect (cover) cherries from birds, watch for pests on fruit trees, shrubs and roses.  Wash aphids off with a force of water.  Set out apple maggot traps in early to mid-June (1 for each dwarf tree; 2-3 for each semi-dwarf tree; and up to 6 for a full-sized tree).  Scrape off bugs and apply a fresh coating every two weeks. Remove loose bark and wrap trunks with cardboard or burlap, periodically removing it to capture codling moth pupae.  During the growing season, remove branches affected by fire blight, cutting at least 6 inches below affected wood.  Sterilize tools with alcohol or a 10% bleach solution between cuts.   Set out peach borer traps by the 15th.  

Trim evergreens and all types of hedges, and be sure to water lawns in hot weather. 

MAY GARDENING CALENDAR

MAY GARDENING CALENDAR

It looks like this year May is going to be our primary planting month, due to the cold spring.  Some general duties to perform: mulch berries, hill leeks, watch for pests: cutworms, pea weevils, root maggot flies, aphids, powdery mildew.  Watch for frosts before putting out tender plants or have row covers and/or tunnels ready.  Harden off plants for a week to ten days before planting in the open garden.  Plant successive crops of cool-loving crops until the end of the month.  Hoe and weed beds.  Weeding is very important in May.

VEGETABLES

Sow indoors first week of the month for transplanting out late in May or early in June: cucumbers, squash, pumpkins, cantaloupes, watermelons, gourds. 

Plant successive crops of: lettuce, spinach, beets, onions, potatoes, peas, and turnips. 

Direct sow (usually about May 10): beans, corn, dill, edamame soy beans, lettuce, spinach, NZ spinach, okra, parsley, leeks, parsnips, scallions, summer savory, sunflowers.  Late in the month, when soil has warmed, direct sow: Lima beans, cantaloupes, cucumbers, okra, pumpkins, squash, and watermelons. 

Transplant out early: artichokes, broccoli, Brussels sprouts, cabbage, cauliflower, leeks, Asian greens, pak choi, and tomatoes (if you can cover them when it gets cold).  Late in the month, if weather permits or you have cover, transplant out: peppers, eggplant, cantaloupes, cucumbers, okra, pumpkins, squash, and watermelons.

Harvest: asparagus, greens, rhubarb.  From frames, a cold tunnel or greenhouse, harvest: radishes, lettuce, turnips, peas, and any cole crops you have started early and grown through winter months. 

Watch for pests: root maggots, wireworms, cutworms, and cabbage butterflies.  Cover crops with netting, row covers, tunnels and fabric.  Use cans or milk jugs with both ends cut out for cutworms, especially on cole crops (brassicas), tomatoes and cucumbers. 

FLOWERS

May 1, finish sowing zinnias and scarlet runner beans for transplanting out later.  Sow direct outside (usually May 10 or so): China asters, cosmos, annual dianthus, balsam, moonvine, morning glory, vinca, marigolds, browallias, sunflowers, runner beans, bachelor’s buttons, castor beans, cockscomb, nicotiana, nasturtiums, poppies, sweet sultan,  sweet peas, gomphrena, annual grasses, stocks, bells of Ireland, bupleurum,  ammi. 

Late in the month, direct sow: annual euphorbia and gypsophila.  Transplant out tender flowers when frosts are over.  Transplant out perennials started from seed in January after hardening off.  

Shade ranunculuses, anemones, and bulb seedlings; take up fall-flowering bulbs and dry for summer storage.  Propagate bulbs by offsets.  Keep a careful watch over newly planted pansies, violets, violas; watering if needed.  Check for pest damage; prepare manure tea. 

FRUIT

Set out apple maggot lures before bloom, if not already done. 

Thin tree fruits after bloom so no fruit touches (this discourages codling moths); protect (cover) cherries from birds.  Watch for pests on fruit trees, shrubs, roses.  Wash off with a force of water.  Set out peach borer traps by the 15th.  Set out apple maggot traps late in the month or in early June.  Remove fallen fruit weekly to discourage codling moths.  Remove loose bark and wrap trunks with cardboard or burlap, periodically removing it capture codling moth pupae.  During growing season, remove branches affected by fire blight at least 6” below affected area.  Between cuts, dip tools in alcohol or a 10% bleach solution. 

Make sure to water newly planted fruit trees and strawberries.  Trim off runners of strawberries to increase production, if not needed for propagation.  

Make softwood cuttings now until midsummer of grapes.

TREES, SHRUBS AND ROSES

Watch for tent caterpillars late in the month.  BT will control them. 

Cut off any dead or diseased wood on roses, sealing the cuts with water-based or wood glue to discourage wasp cane borers.  Spread bone meal, Epsom salts and composted manure or alfalfa meal around roses, leaving a 2” empty space on the surface of the soil around rose stems.  Take softwood cuttings of roses after petal fall.

APRIL GARDENING CALENDAR

Our picture today is a photograph of a green-edged auricula primrose.  As a whole, the auricula section of the genus Primula is fascinating, diverse, and quite varied in form and color.  A hundred and fifty years ago auricula primroses were extremely popular plants in Europe and America.   April is their prime bloom time!  

GENERAL APRIL GARDENING CALENDAR

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.

Above are  two antique engravings.  The one on the left shows a box of perfectly formed vegetables entered in a Victorian garden show.  The other engraving is of a Victorian era greenhouse.  In Victorian times gardening was mostly practiced organically; consequently, the varieties of flowers and vegetables they grew (that are still with us) are adapted to organic conditions.  They are open-pollinated, therefore are an important sustainable resource; many are well-adapted to our tough local climate; and best of all, they are wonderfully flavorful!

Now is the time to start many tender vegetables and annuals to be set out later into the garden, as weather warms.  Have a great spring!

FEBRUARY GARDENING CALENDAR

Standard

fullsizerender-13

FEBRUARY GARDENING CALENDAR

February is a winter month for us and usually not much can be done outside besides shoveling snow.  But seed catalogs are still arriving and seed racks are in stores and garden centers now, so we can plan the garden.  It is a good time to order new bare root plants for spring delivery (such as most perennials, roses, etc.).   Later, in the spring, potted plants will be available in local nurseries.

If you have hotbeds (heated frames) you can sow several kinds of seed directly into the soil: arugula, carrots, celery, corn salad, fava beans, cress, mustard and turnip greens, onions, peas, radishes and spinach.  Inside, under lights, you can sow eggplant, onions and peppers to be grown on and transplanted out later.  It might be better to wait to start tomatoes unless you have a good light system or greenhouse, because the plants will get “leggy” reaching for light inside during our short winter days.  Some slow-growing flowers can be started inside now under lights, including: petunias, impatiens, lobelia, pansies, salvias, and perennial herbs and flowers.  (Cover pansy seeds well as they need darkness to germinate).  Check and ventilate cold frames and keep them covered at night.

Continue forcing flowers in the greenhouse, such as tulips, narcissus, roses and lily of the valley.   Strawberries can be forced now in the greenhouse also.  Protect alpines, auriculas and other primroses in pots (in a cold greenhouse) from too much rain or frosts as they will begin to bud.  Pick off dead leaves, remove the top of the soil off of the pot and replace it with rich compost.  After adding compost, clean the outside of the flower pots with warm soapy water.   Only a little water may be given to the plants, but give plentiful air.  Sow any remaining alpine, wildflower, primula and auricula seeds.

Late in the month, if weather permits, sow hardy annuals outside: cornflowers, alyssum (Lobularia maritima) larkspur, sweet peas, Lychnis, Nigella, Lavatera, poppies, kiss-me-by-the-garden-gate, dill and wildflowers.  If the snow is gone you can begin planting and/or pruning fruit trees: peaches, plums, cherries, nectarines, apples, medlars, quinces and pears.  Plant and/or prune: gooseberries, currants and raspberries.  Manure and other organics can be spread outside over vegetable beds, if this was not already done in December.  Prune and manure grapes, leaving space around the stems.  Grapes can be grafted late in the month.

In late February you can sow stone fruit seeds for rootstocks and hawthorn seeds for hedges; later transplanting them to their permanent position (after three years).

Late in the month is a good time to begin planting and dividing perennials (if the snow is gone and the ground thawed).  Also, if weather permits, propagate roses and other shrubs by suckers, layering and cuttings.

JANUARY GARDENING CALENDAR

 

This is the time to plan your 2017 garden.  Seed racks will be in garden stores soon.  Nowadays there are several companies selling organically grown seeds, some of them grown right here in the Flathead area!  January is an excellent time to test the germination rate on your saved seeds.  You can get a rough estimate of percentage if you sprout some now.  Put ten seeds folded into a moist paper towel.  Place the moist towel on a plate, loosely covered with plastic wrap or waxed paper and put it in a warm place to test germ.  The top of the refrigerator is a convenient spot to do this.  If 9 out of 10 seeds germinate you can bet on about a 90% germ.  If a variety germinates poorly, you can plant extra seeds if you have them, or buy fresh seed.  Also, check past records and eliminate any varieties that you did not like, or did not do well in your garden.  Composted manure can be spread on vegetable beds, right on top of the snow if you want.  Spring melt and rains will draw nutrients down into the soil.  This month is a good time to repair garden tools, and obtain or make plant supports and cold frames.  Locate frames and hotbeds for winter/spring growing outside in sunny, protected locations.

Check stored fruits and vegetables for spoilage.  Watch cold frames; admit air on days when the temperature goes above freezing and be sure to cover them at night.  Clean and weed lettuces and other winter greens growing in cold tunnels or frames.  Use leftover Christmas tree boughs to mulch perennials, strawberries, roses, etc.

Prepare any planned garden designs.  Be sure to rotate planting locations of vegetables and flowers every season for best health and disease prevention.

Indoors, sow strawberries and perennials early.  Beginning the 15th, sow cauliflower and cabbage seed inside for growing in frames.  Sow eggplant, onions, leeks, and early peppers.  Sow perennial herbs: oregano, thyme, feverfew, Greek oregano, lavender, rosemary, chives, chamomile, hyssop, horehound, catnip, parsley, rue, lemon balm and salvia.

Harvest winter greens from frames and tunnels as well as spinach, lettuce, kale, chard, onions, parsnips, leeks and carrots.

Sow primrose and auricula seed in a cool greenhouse; protect auriculas from severe frost and rains.  Ventilate auriculas and other alpines in the greenhouse—keep plants on the dry side as they will be dormant.  Prepare to top dress containerized plants (in a cool greenhouse) with manure or compost in February.

Ventilate sweet violet frames daily; pick off dead foliage and keep the glass clean.  Transfer potted sweet violets, pansies and violas to the greenhouse to flower.  Other plants (previously potted) to force inside now include: honeysuckle, roses, jasmine, carnations, sweet William, wallflowers, stocks, narcissus, ranunculus, early dwarf tulips and lily of the valley.  Take cuttings of geraniums and fuchsias.  Force potted strawberries (potted in Sept.) in hotbeds or greenhouse.  Check winter mulches and covers; mound up snow to keep perennials and roses protected from dry cold.  Have a great gardening year in 2017!

 

DECEMBER GARDENING CALENDAR

Standard

img_4202

 

Shown in the photograph above is North Crow Creek Canyon in the Mission Mountains of Western Montana.  I have a beautiful view of the canyon from my front yard.  Snow is piling up now that winter is here.  December is probably the least busy month for gardening of the year in colder climates like ours.  Here are a few things we might need to do.

Check stored vegetables and fruit often; inventory seeds and test germination of last year’s seed.  Plan your 2017 garden and order seed.  Keep perennials and bulbs planted 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 frames every night with mats, blankets, straw, ferns or insulating row fabric.  Late cabbages, kale and greens should be under 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 and phloxes.  Spread composted manure over the vegetable garden.  Over the winter the manure will break down and feed the soil.  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 or garlic/herb spray every 3 days for 2 weeks.  Another method to control spider mites is to spray foliage every day with water.  Spider mites do not like frequently  wet foliage.  Do not over water 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 hardy plants in cold frames, keep admitting air into the frames when it is warm enough 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 cuttings 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 out of direct sun or in shade .  The cuttings should root over the winter.

NOVEMBER GARDENING CALENDAR

Standard

fullsizerender-8

NOVEMBER GARDENING CALENDAR

GENERAL

Early in the month, prepare beds for next spring’s early crops; add manure and trench into furrows to receive frost (this will break down and lighten/feed the soil).

Check over which varieties of flowers and vegetables you liked or disliked, which ones did well, and make a note of it.  Keep records up to date.  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.

VEGETABLES

Finish planting garlic, shallots, and Egyptian walking onions.

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 tops off.  Dig a pit in a dry place if possible.  Put down 2 inches of sand, then roots, then more sand, alternating.  Then cover with sand again and straw to protect them.

Admit air to cold frames and greenhouse on sunny days; pick off any mildewed or moldy leaves.  Force asparagus in hotbeds.  Manure outdoor asparagus and rhubarb 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.

FLOWERS

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.  Pot up double daisies; keep in frames.  Move potted flowers to frames to protect them from heavy rains.  Take and root cuttings of Pulsatilla.

Cut back established pansies, collect violet seed, continue to ventilate frames.  Prepare pansy and violet beds for planting.

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 newly planted tulips, crocus and hyacinths to discourage squirrels.

In the greenhouse admit air; the plants will be at rest.  Keep foliage dry, do not over water or not at all!  If mold appears, dust with sulfur.  Plunge pots of border auriculas, primroses and carnations up to the rims into gravel or soil in a frame.  Be sure to give air.  Cover frames if frosty and cold, letting no sun shine on them when frozen.  If you have bulbs, perennials, roses or shrubs growing in pots outside, be sure to sink them up to the rims into soil, sawdust or gravel to protect them from cold over winter.

FRUIT
