Gardeners Calendar: To Do in June

by Gary Crispell, EMGV

It’s June? (very soon!) OMG!! Did May ever happen? I hope you are more ready for summer than I. Although, ready or not, here it comes. Forthwith a hopefully helpful list of possible gardening activities presented for your perusal.

Lawn Care

If you have heretofore procrastinated on this item it is TIME to fertilize warm season grasses (i.e. Bermuda, Zoysia, St. Augustine). It is also the best (and really only) time to fertilize Centipede. The general recommendation is for half a pound 15-0-14 or equivalent per 1000 sq ft. Should you desire to be truly accurate–GET a FREE SOIL TEST.

It would be difficult to core aerate our clayey soils too much, so a day or two after a rain or a good irrigation would be an ideal time to do just that.

When mowing warm season grasses a good rule of thumb is to remove one-third of the new growth per mowing.

If you have been drooling over your neighbor’s Zoysia lawn June is a good time to start your own with sod or plugs.

Fertilizing

After getting your FREE SOIL TEST in order to avoid over fertilizing, now is the time to feed your dogwoods following the recommendations.

Vegetable gardens would like a side dressing of fertilizer about now to maximize production.

Planting

Again, for the procrastinators out there, if you want a crop this year better get these plants (too late for seeds) in the ground ASAP: tomatoes, peppers, black-eyed peas, lima beans, green & wax beans, pumpkins, sweet potatoes.

Start (from seed) Brussel sprouts and collards to set out in mid-July.

Pruning

Coniferous evergreens–they produce seeds in cones–like pines, cedars, junipers, arborvitaes, etc. may be pruned now.

Hedges can be pruned now but be advised: Do not remove more than one-third of the total plant top (the green part).

Keep pinching your garden mums until mid-July.

Hydrangea macrophylla (the ones with the BIG leaves) can be pruned when the flowers fade.

Azaleas may be pruned until July 4. (An “old wives tale” that works.)

Dieback in ericaceous plants (acid-loving) such as azalea, rhododendron, Pieris, etc. can be pruned out now. Remember to cut below the damage and to sterilize the pruner with 10% bleach between cuts.

Pest Control and Herbicides

Patrol your shrubs for the following likely suspects: lace bugs, leaf miners, spider mites, aphids and bag worms. Use appropriate measures to curtail their destructive tendencies. If the bag worms have already bagged themselves you will have to hand pick them and destroy them in any manner you see fittin’.

June is also the beginning of the Asian invasion better known as Japanese beetles.  There is a myriad of treatment options out there.

Tomato early blight could be rampant this year what with all the warm dampness.  Watch for dark spots on the leaves and treat with an appropriate fungicide. There are some good organics out there.

June is a good month to eradicate poison ivy, kudzu and honeysuckle. Get ‘em with an appropriate herbicide while they are rapidly growing.

As with shrubs it is time to be on guard in the garden. Several (many?) insects are looking for gourmet gardens to satisfy their gastronomic inclinations. Look for a variety of worms on cruciferous veggies (cabbage, broccoli, cauliflower), cucumber beetles on cucumbers (ironically), squash borers on other cucurbits–squash and melons, flea beetles on green beans, tomatoes and eggplant, and aphids on anything green.

Continue with regular pest management programs on bunch grapes, fruit trees and roses.

Use pesticides wisely, sparingly and only when necessary. Always read the label and follow directions.

Other Fun Garden Stuff to Keep You Outside

Water lawns as necessary but try to do it early in the day to avoid evaporative loss.  Watering lawn in the evening promotes disease. Lawns and gardens need about one inch of water per week either from natural sources or irrigation.

Strawberry beds can be renovated now.

June is also a marvelous time to sit on the deck or patio with a glass of your favorite cold beverage and enjoy your garden.
