August Gardening Tips

— Written By

Lawn

  • Late summer is the most effective time to control fire ants with baits.
  • Treat lawns for grubs only if you find more than 5 grubs per square foot.
  • August is the last month to fertilize bermudagrass, St. Augustinegrass, and zoysiagrass. It is recommended to apply 1 pound of Nitrogen per 1,000 square feet.

Trees, Shrubs, and Flowers

  • Now is the time to start making plans for planting trees. Fall is the best time to plant trees and shrubs in the landscape. August is a good time to analyze your site and make decisions on what to plant this coming fall.
  • Do not prune or fertilize landscape shrubs for the remainder of the year to allow them to prepare for dormancy. Properly acclimated plants have a greater degree of winter hardiness.
  • Fall webworms form large masses of webbing on branch ends but usually do not cause much damage. If unsightly, rip webs open with a long pole or disrupt with a strong stream of water.
  • Pull up tired annuals and dead-head those that are healthy.
  • Get a second bloom from faded annuals by cutting them back by one third their height, then feed with a liquid fertilizer.

Fruit, Vegetables, and Herbs

  • Be on the outlook for the pecan weevil. The pecan weevil usually emerges from the soil in early August after significant rainfall. Treatments should begin the first of August after a rainfall. Drench the trunk and lower limbs with insecticide (Sevin).
  • Order seeds for your fall vegetable garden.
  • To grow your own transplants, start the seed of broccoli, kale, collard, cabbage, Chinese cabbage, and cauliflower in containers of potting soil this month.
  • Sow parsley seed direct in the garden or in containers. Soak seed in warm water for 6 to 8 hours before sowing.
  • Sow lettuce, spinach, arugula, and other salad greens in the garden or grow in containers.
  • Direct seed carrots, beets, rutabaga, and kohlrabi.
  • Spray peach tree trunks with permethrin to prevent peach tree borers from killing trees.
