When to Plant in Atlanta, GA

Atlanta sits in the Georgia Piedmont — Zone 7b/8a with a typical last frost around March 29. The metro area's urban heat island gives city gardeners a slightly longer season than surrounding suburban and rural areas.

Atlanta's climate offers excellent spring and fall growing windows with hot, humid summers that challenge some crops. The fall garden from August through November is outstanding, and Atlanta's mild winters support cool-season crops with minimal protection.

This month in Atlanta: October 2026

Atlanta's first frost usually comes around November 6, so October is still prime fall growing. Inside the Perimeter it often holds off a little longer than out in the northern suburbs.

There's time early this month to sow spinach, lettuce, arugula, and radishes, and to set out kale, collard, and cabbage transplants if you haven't yet. Carrots sown in the first week of October will be small but sweet by December.

Keep the summer crops picked while they're still producing. As they finish, cut them at the soil line and put compost on the empty squares. Plant garlic late in the month or in early November.
