Every month we’ll bring you fresh gardening ideas and tips, professional advice, and techniques both new and traditional for you to apply to your own home garden and make it the best it can be.
- Continue to plant warm season turf grasses (Bermuda, St. Augustine, and Zoysia).
- Continue to plant ground covers, tropical and warm season annuals.
- Plant sweet and hot peppers, okra and tomatoes (first half of month) for fall harvest.
- Prune out any dead or broken branches of woody ornamentals (trees and shrubs), but avoid major pruning during the heat of summer.
- Cut back spent flowers of annuals and perennials to encourage new blooms.
- Pay attention to the water needs of lawns, ornamental plants, and vegetables in the typically hot dry days of mid-summer, being attentive particularly to new plants with undeveloped root systems and to outdoor potted plants, which can dry out quickly. Water in the early morning hours (3 AM to 8 AM) to minimize fungal problems and evaporation.
- Continue to check crape myrtles for aphids.
- Continue to check ornamentals, flowers, and vegetables for spider mites.
- Inspect broadleaf evergreen shrubs such as euonymus and hollies for scale insects, and treat as necessary.
- Watch for lace bugs on azaleas, pyracantha, cotoneaster, and lantana.
- Fertilize chrysanthemums if needed.
- Mow turf grasses every 5 to 7 days, maintain Bermuda at 1 to 1 ½ inches and St. Augustine at 2 ½ in full sun and 3 to 3 ½ in semi-shade.
- Continue to check for chinch bugs and gray leaf spot fungus in St. Augustine lawns.
- Check lawn for grub worms by digging in several places. Grub treatments, if needed, are recommended if you find more than four grubs per square foot.
- Fertilize hanging baskets and other container plants regularly if needed.
- Harvest vegetables as they ripen.
To reduce mosquito pests, check house gutters and any containers for standing water. For mosquito larva control, use Bti (Bacillus thuringiensis, israelensis) as a larvicide.
