Garden tips for August

By Ray Ridlen

• Water all plantings thoroughly unless rainfall has been adequate. It is better to water more in depth, less often and early in the morning.

• The fall vegetable garden is planted now.

• Divide and replant spring blooming perennials like irises, peonies and daylilies, if needed.

• Irrigated warm-season lawns may be fertilized again.

• Hedges and shrubs can be pruned, if necessary, about mid-August.

• Young trees and shrubs may be fertilized again.

• Discontinue dead-heading roses by mid-August to help initiate winter hardiness.

• Brown patch disease of cool-season grasses can be a problem.

• Meet water requirements of turf.

• For areas being converted to tall fescue this fall, begin spraying bermudagrass with glyphosate products in early-August.

• White grub damage can become visible this month. Apply appropriate soil insecticide if white grubs are a problem. Water product into soil.

• Watch for a second generation of fall webworm in late August/early-September.

• Pre-emergent herbicides for winter-annual weed control in warm-season grasses can be applied in late-August. Water in the product after application.

General

Water your compost during extremely dry periods so that it remains active.

Always follow directions on both synthetic and natural pesticide products.

Watch for high populations of caterpillars, aphids, spider mites, thrips, scales and other insects on plant material in the garden and landscape and treat as needed.

Fall fescue should be mowed at 3” during the hot summers and even up to 3 ½“ if growing under heavier shade. Warm season lawns like Bermudagrass and Zoysia-garass should be gradually raised to around 2” to 2 ½” to better adjust for heat stress and the onset of fall.

Avoid late applications of fertilizer on woody plants at this time. The next best time to fertilize woody plants will be mid to late October.

Vegetables

August is a good month to start your fall vegetable garden. Bush beans, cucumbers and summer squash can be replanted for another crop. Beets, broccoli, carrots, potatoes, lettuce and other cool season crops can also be planted at this time.

Soak vegetable seed overnight prior to planting. Once planted, cover them with compost to avoid soil crusting. Mulching will keep planting bed moist and provide shade during initial establishment of vegetables. Monitor and control insect pests that prevent a good start of plants in your fall garden.
