Kent Gardener Maggie L. Moor-Orth gives her gardening update for the month of August with tips and what gardeners should be doing.
Here is your August gardening update.
The first week of August
Mid-AugustApply a second treatment of lawn insecticide for grub control or use milky spore dust, a bacteria that will attack over forty species of white grubs; this can be applied any time. Collect materials for dried flower arrangements, including weeds, flowers, marsh grasses and foliage. Prepare lawn or lawn areas that are going to be seeded. Harvest ripened vegetables. Sweet corn is ready when ears feel full and firm and the silks have turned brown and dried. Cantaloupes are ready to eat when stems slip or separate easily from the fruit. Feed roses for the last time. Continue to compost grass clippings, pruned pieces, and weeds that have not gone to seed. Check azaleas if they are beginning to look pale green to yellow. This is called chloritic. Check soil pH. These acid-loving plants may need to be fed. Continue to hang harvested herbs. Check vegetable and other plants for evidence of insects and disease.
Late AugustRefrigerate grapes after harvesting because they perish easily. Inspect trunks and branches of dogwoods and other trees for injured bark or fine dust pushed from burrows in trunk by borers. Fertilize fall vegetable garden plants. Plant new lawns or reseed bare spots in old lawns. This can be done until Sept. 30 in Delaware. If it’s dry, be sure to water newly seeded lawns every day. Harvest ripened vegetables and share extras with non-gardening friends and neighbors. Harvest and hang small bunches of herbs before they flower. Tie in little bunches and hang in a ventilated warm space to cure.
