August Vegetable Gardening Calendar

To use this calendar, consider middle Georgia as a belt across the state from Columbus through Macon to Augusta. In north Georgia, the spring planting dates are from one to three weeks later as you progress northward through the mountain counties; fall planting dates are about two weeks earlier.

The following recommendations are based on long-term average dates of the last killing frost in the spring and first killing frost in the fall. Every year does not conform to the “average,” so you should use your own judgment about advancing or delaying the time for each job, depending on weather conditions.

  • Plant the following no later than the dates indicated below:
    August 15: Snap beans and Irish potatoes (seed can be sprouted two to three weeks before planting).
    August 31: Cucumbers and squash; plant varieties resistant to downy mildew.
  • In order to calculate the planting date, determine the frost date and count back the number of days to maturity plus 18 days for harvest of the crop. If snap beans mature in 55 days and your frost date is November 15, you should plant on or before September 3.
  • Start plants for broccoli, cabbage, cauliflower, collards, kale and onions in a half-shaded area for setting out in September.
  • Prepare soil for September to October plantings of “cool-season” crops. Apply fertilizer and prepare seeded so rains will settle the rows and make it easier to get seeds to germinate when they are planted.
  • If watering is necessary to get a stand, open the furrow for seed, pour in water, plant seed and cover. Use starter solution on the transplanted crops.
  • Water the garden as needed to prevent drought stress.
