August Delaware Garden Guide

<<July Garden Calendar

The following article is your August gardening update.

The first week of August:

  •   Now is an ideal time to take pictures and plan for next year’s vegetable and flower gardens.
  •   Order your spring flowering bulbs now.
  •   Check your garden plants, shrubs, flowers, and trees for diseases and insect pest.
  •   Begin planning and planting your fall vegetables, such as lettuce, radishes, kale, spinach, carrots, Brussel sprouts, cauliflower and peas.
  •   Pinch back to remove dead heads from annuals.
  •   Remember to make arrangements with a friend or family members to water your house plants while you’re away on vacation.
  •  Harvest vine-ripened vegetables.  Share extras with non-gardening friends and neighbors.
  •  Harvest and hang herbs before they go into bloom.  Tie in little bunches and hang in a ventilated warm space to cure.  After thoroughly dried, put in sealed jars to use in the water.


  •  Apply 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.  The Kent County Master Gardeners are going to have a workshop on Lawn Establishment on August 12, 1997.  If you would like to attend, call #730-4000 to pre-register and/or for more information.
  •  Harvest ripened vegetables.  Sweet corn is ready when ears feel full and firm and the silks have turned brown and dry; cantaloupes are already to eat when stems slip or separate easily from the fruit.
  •  Feed roses for the last time.
  •  Continue to compost grass clippings, pruning 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 insect pests and disease.

Late August: 

  •  Grapes that are ripening now perish easily so keep refrigerated after harvesting.
  •  Inspect trunks and branches of dogwoods and other trees for injured bark or fine dusk 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 September 30th 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.
