To ensure success for your crops, direct-sow seeds as early as possible in August. If your frost date is rapidly approaching, look for fast-maturing crops or plant starts instead of sowing seeds. It also helps to choose semi-hardy vegetables that can withstand a light early frost.

Depending on what you're planting and what U.S. Department of Agriculture growing region you live in, August plantings may be more successful in containers, which can easily be moved between shady and sunny spots as needed. Wherever you're planting, be sure to spread a thin layer of mulch over freshly turned and watered soil to prevent it from forming a crust, which can stunt sprouting plants and lose valuable water.
