Coastal and Tropical South
Lighten Up Crape Myrtles
If rainfall weighed down the big flowerheads on crape myrtles, clip off the ruined flowers and an inch of two of the stem, but no more. This will help prevent branches from breaking and will help revive drooping ones.
Fungal diseases are always present; when temperature and humidity are right, they flourish. Zinnia leaves are susceptible and flowers will suffer if leaves are badly ravaged by disease. At the first sign of spots, pluck off those leaves and use a baking soda or fungicidal soap spray to slow them down.
Plant pumpkin seeds now for decorating and jack o'-lanterns. Choose centerpiece shapes like Cinderella's coach, or rounded and smoother varieties for carving. Minis can grow up a trellis, but bigger types need room to crawl. Plant three seeds at the center of a slightly raised hill with 6 feet between hills.
Tree trunks, lawns, and shady areas under trees can be covered in a mossy blanket. Most of the time it is harmless and even cultivated for its interesting textures. But if it seems to be smothering the grass or rotting the roots it grows over, dust garden lime on the area to control the moss.
Though it is too late to prune azaleas without losing next year's flowers, some still need attention. If they didn't bloom, or have declined so that few leaves are left, go ahead and do rejuvenative pruning. Cut them down by half (use a saw if needed), spray with ultrafine oil, fertilize, and mulch.
