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!

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

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.

Controlling Cut Worms

Standard

In my organic garden of heirloom plants here in Oregon, we have several pests: deer, raccoons, dogs, squirrels, rats, slugs, cabbage looper larvae and cutworms.  Cutworms have been the most consistently damaging of the group.  Typically, they sever the stems of young transplants, a preferred food of theirs.  They also eat most of the plants I grow; all vegetables, but especially plants of the Brassica, Dianthus, Primula and Viola families.  Here, they are a year-round pest, perhaps because of the mild weather of the region.  Cutworms belong to the family Noctuidae.  Note that the Latin root word here “noctu” refers to night—the time when these insects feed.  They come out about two hours after dark to feast, then disappear under the soil for the day.  Some cutworm eggs overwinter and hatch in spring, but others can hatch at any time after, as long as it is not too cold.  Evidently there is one generation per year.  The adult moths emerge in late summer and lay eggs which can hatch at varying times of the year.  Several species exist: the Army cutworm, Black cutworm, Variegated cutworm, and a new species here in Oregon, which is active year round, the Winter cutworm.  The first picture above shows a cutworm that appeared on heirloom petunia seedlings while they were on a bench in my greenhouse.  The plants had been transplanted two weeks before, so I was surprised that the cutworm was able to climb so far!  the photo was taken in May, so this was probably the variegated cutworm, which we have spring, summer and fall.  The second picture shows another cutworm on the edge of a patio planter, three feet above the ground.  The other three photos reveal damage on in-ground plants made by Winter cutworms in December, January and February.  Cutworms typically leave black droppings on your plants; the photo of the cauliflower shows this.

An organic gardener’s best first defense against cutworms is prevention.  A week before plants are to be set out, prepare your bed by cultivating heavily to dislodge and destroy any worms in the soil, then cultivate again.  When you plant your transplants, place collars around the plants to make it difficult for the worms to get to your plants.  Collars may be made of paper (milk cartons work well), plastic, metal or cardboard.  Here it rains so frequently that I choose to use plastic milk jugs or cans with the bottoms cut out of them.  After planting, spread one or more of the following sharp-edged deterrent mulches over the soil, around the plants: diatomaceous earth, eggshells, wood ashes or sharp grit.  The rough surfaces of any of these will discourage cutworms from crawling to your plants.  Another preventive method is to wait until two hours after dark, take a flashlight, search out the larvae and use the squish-bug technique for control.  Continue to cultivate around your plants to dislodge hiding larvae.  One other way to fight the battle is to attract or purchase beneficial insects to control cutworms.  Ground beetles, parasitic nematodes and tachinid flies attack cutworms.  Pollen-laden flowers, (don’t forget about native wildflowers) will help draw beneficial insects to your garden.

A next recourse for severe infestations is to use biological pest controls.  The bacteria Bacillus thuringensis kurstaki (known as BTK) made into a liquid spray is effective in controlling cutworms as long as you do not have continuous rain, as we often do here in western Oregon.  The damaged cauliflower, cabbage and primrose in the photos above show the effects of cutworms in winter, during a three month-long period of rain.  Dry BTK can be mixed with moistened bran to act as a bait and will last a few days until washed away.  Of course one can use the handpick squishbug method, but it might be difficult to keep up!  BTK cannot be used over and over without enabling cutworms to develop resistance.  Take care not to spray anything other than the very plants you need to protect when the larvae of butterflies are present.  Organically approved pesticides containing pyrethrin may also be used for heavy infestations.
