Pests. If you find fall webworms in your trees — hickory, walnut, birch, cherry and crabapple, to name a few — pull them out and dump the caterpillars into a bucket of soapy water. This is a good control measure for those nests within reach. For those nests that aren’t within reach, you may have to resort to spraying. Control webworms with BTK (Bacillus thuringiensis). Apply just to the affected branches; using BTK as a broad spray will harm beneficial insects as well.More:Planting guides for your Southeast gardenBrowse flowers, plants and garden design ideas

Treat for webworms. Webworms cause many problems in our trees, particularly pecan trees, and August is usually the worst month for this damage. Webworms start their activity around June, and because they have three to four generations a year, they continue to cause problems into the fall. Try releasing trichogramma wasps in three rounds, two weeks apart, starting in early August. Trichogramma wasps are tiny predators that eat webworm eggs before they become a major problem — call your county extension office or trusted local garden center to inquire about the availability of these wasps in your area. And don't worry — these beneficial bugs only attack pests' eggs, not people, making them welcome in every garden.

Maintain. July is a great month to simply stay on top of what you have already created — pull weeds, pull up dead plants, remove dead limbs, remulch if necessary, turn your compost pile and water smartly (see below). Webworms are very damaging to our pecan trees, and August is typically the worst month for webworm damage. Releasing trichogramma wasps now can help with webworm control. Trichogramma wasps do not sting human beings, but they do parasitize the eggs of webworms. These wasps can be mail ordered — check with your local county extension agent for the best source of these wasps near you.
