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/

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

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.  Make hardwood cuttings of Prunus and Vitis cultivars.

TREES, SHRUBS AND ROSES

Finish planting deciduous shrubs and trees.  Layer clematis, divide Mahonias; take cuttings of lavender, Forsythia, Rubus and lilacs.

March is a very busy month for gardeners.  Root crops stored from the previous year and planned to produce seed can be planted out late in the month after the soil thaws (cabbages, celery, lettuce, leeks, onions, parsnips).  Planting time will arrive soon, or has already arrived for those of you in mild climates.  Weed and clean borders and vegetable beds, plant perennials, sow seeds of hardy annuals, plant rhubarb, asparagus, sea kale and artichokes.   Plant and/or prune cane fruits and fruit trees (cherries, apples, peaches, apricots, pears, plums, currants, gooseberries, etc.).  Check cold frames on a regular basis, venting as needed and closing the glazing panels at night.  Watch temperatures in the greenhouse also, as March is a month of ups and downs in temperature.  Manure and other organic soil amendments (epsom salts, seaweed meal, alfalfa meal, greensand, bone meal, compost and wood ashes) can be spread over vegetable, fruit, flower and rose beds.  Grape vines can be manured now, leaving space around the stem; treat roses in the same manner.

Many vegetables can be sown indoors now for transplanting out later: cole crops (brassicas), onions, lettuce, peppers, eggplant and leeks.  Some vegetables can be direct sown outside if weather permits and if your soil is not too wet to work: arugula, carrots, corn salad, fava beans, cress, mustard and turnip greens, onions, peas, radishes and spinach.  Celery and lettuce can be direct sown into frames.  Several vegetables and fruits can be transplanted now: raspberries, blackberries, strawberries, asparagus, horseradish, head lettuce, onion sets and plants and perennial herbs.  Make sure your mushroom beds do not get too wet; replace straw if wet.

Potted auricula primroses should be protected from rain and frosts; they will begin to bud soon.  Sow any remaining auricula and primrose seeds.  Herbaceous perennials can be divided and planted now.  Many hardy annual flowers may be sown during March: larkspur, sweet peas, lychnis, nigella, lavatera, poppies, kiss-me-by-the-garden-gate and sweet alyssum.  Inside the greenhouse sow: petunias, impatiens, pansies, alyssum, chrysanthemums, iceplants, portulacas, salvias, snapdragons, sweet Williams, ten-week stocks, mignonette, hesperis, Shasta daisies, hibiscus, lupine and Salvia x superba.

Roses and other shrubs may be layered now, and cuttings may be made of geraniums, myrtles and hydrangeas.  If you want to plant a hedge from seed, now is the time to sow seeds of hawthorns, stone fruits, roses and other hardy shrubs you might like to use.  The young plants can be transplanted out to their permanent positions later.

Happy Spring!
