Things to do in July


Give annuals a complete fertilizer, well before and after application. Deadhead and fertilize roses. Fertilize young fruit trees (except pears) with a 3-1-2 ratio product at 1-2 cups per inch of trunk diameter.


Water all planted areas deeply but infrequently during dry periods. Outdoor container plants need daily watering. Consider landscaping with drought resistant native plants in the future. SOIL: Mulch all bare soil. Turn compost pile and add new ingredients. Clean up spring vegetable gardens and replenish with compost.

Lawn Care:

Mow every 5-7 days and leave the clippings on the lawn. Watch for take-all patch. Set mower higher in shady areas to promote denser turf.

Diseases/Pests to Look for:

spider mites

leaf rollers

lacebugs and aphids

chinch bugs



chiggers and grubs in lawns;

scale insects on euonymus, hollies, peaches and plums;

webworms in pecans and persimmons;

powdery mildew on crape myrtles and roses;

aphids on crape myrtle, roses and Mexican milkweed;

scale on peaches and plums.

Remove any diseased leaves from beds; do not add to compost.


Remove vigorous growth from center of peach and plum trees to prevent shading of fruiting shoots. Tip new blackberry canes at 4’ to force side branches. Prune dead and damaged wood from trees and shrubs as needed.
