Tired petunias will rebound beautifully if you prune them back by half their size. After pruning, drench the plants with a mix-with-water plant food. The same treatment can rejuvenate other annuals, including impatiens, coleus, salvia, and zinnias.
As soon as the last fruits are gone, blueberry plants get busy developing next year\'s buds. Support this process by giving the plants a light feeding with an organic or timed-release fertilizer. Also replenish mulch around plants to protect the shallow surface roots from heat and dryness.
Set Out Brassicas
Set out healthy seedlings of broccoli, brussels sprouts, and cabbage. The best way to protect them from leaf-eating caterpillars is to cover them with floating row covers, held aloft with wood or wire hoops. Mulch around the plants to keep the soil constantly moist.
Fertilize Warm-Season Grasses
If you have a bermuda or zoysia lawn, be ready to fertilize it just before rain is expected. This feeding will help tighten up the turf before it becomes dormant in winter, which will make it more resistant to invasions staged by winter weeds.
Sow Annual Herbs
It\'s time to plant annual herbs again! Sow basil, cilantro, and dill where you want them to grow, and shade the seeded spot for three to four days to keep it from drying out. Add parsley to your collection late in the month, when nights become a little longer and cooler.
