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.
