Planting
- Plant tomatoes and peppers from four-inch pots. Visit Aggie Horticulture
vegetable section for recommended varieties; click HERE to access the site. - Early July is the time to plant small and medium pumpkins for a Halloween harvest.
- Plant heat-tolerant annuals that have been acclimated to hot, sunny conditions. This includes
moss rose, purslane, trailing lantana, purple fountain grass, firebush, and copper plants. - Lawn grasses can be planted this month, but you will need to water twice daily for short intervals to
keep the soil surface moist until the grass has established good roots, usually in two to three weeks.
Fertilizing and Pruning
- Fertilize plants that bloom on new growth, such as crape myrtles, tropical hibiscus, and roses, with a high-nitrogen fertilizer to promote late-summer growth and fall blooms. Apply the same fertilizer to boost summer annuals and fall-flowering perennials.
- Light pruning of erratic spring growth may be done to maintain the natural form. Dead and diseased wood from trees and shrubs should be removed. Major pruning should be postponed until mid-winter.
- Deadhead all blooming plants. Remove dead leaves and spent blooms from container plants.
Garden Watch
- Be a “plant health” detective! Plants respond in various ways to heat and drought stress. These symptoms are often misdiagnosed as an insect or disease problem. Correctly identify the problem before turning to a pesticide.
- Galls on leaves of oaks, hackberries, and other trees are caused by many species of gall-forming insects and are a result of the
female stinging the leaf tissues as she lays her eggs. Galls are harmless since the insect doesn’t feed on plant tissues. - Watch for lawn pests. Dry, light-colored areas in sunny parts of St. Augustine are probably the result of chinch bugs (small black insects with white diamonds on their backs). Apply Merit (imidacloprid) or other labeled insecticide. Grub worms are the culprits if the turf turns brown and easily comes up when pulled on. Treat with a granular insecticide.
- Rapid death of established landscape plants and orchard trees during the summer may signify the presence of cotton root rot, a soil-borne fungal disease common in our calcareous clay soils. Since there is no effective control, verification by the Plant Diagnostic Lab at Texas A&M AgriLife Extension Service will help you know what plants can be used as replacements; click HERE to access the site.
