Tidewater Gardening blooming perennials now. Be sure to stake tall perennials to keep them from falling over. Cut the first f lowers of lavender to encourage a second crop. Helpful hint ~ try rubbing your hands with lavender leaves to remove strong odors, such as garlic or onion. Cut back and fertilize delphinium and phlox to encourage a second show of bloom, and be sure to pinch chrysanthemums for the last time in mid-July. Annuals start to fade in the landscape in mid- to late July. You can rejuvenate them by cutting them back to approximately half their height, then fertilize them with 1/2 cup of 5-10-10 per square yard of planted area, water and apply a 1- to 2-inch layer of mulch. You can also apply a liquid fertilizer or a manure compost “tea” to given them a “shot in the arm,” so to speak. Remove any annuals that didn’t make it, and add them to the compost pile. You can replant beds with hardy annuals or perennials such as calendulas, globe thistles, or sea pinks. Fall webworms (FWW) appear in late July. These larvae feed on more than 100 species of fruit, shade and forest trees. The larvae are pale yellow in color, with dark heads. They live in conspicuous webs of silk that they spin on the

ends of branches of host plants. FWW are often confused with eastern tent caterpillars that produce large webs in the branch crotches of trees in the spring. Offensive webs can be easily pruned from the host plant, and burned or destroyed. Young webs are easier to remove than older, established ones. While young, the caterpillars can also be effectively controlled with several common insecticides, insecticidal soaps, or with B.t. Control is most effective if the web itself is punctured with the spray. These webs are usually more of a nuisance, so just prune the web out when you can reach them. Happy Gardening!
