Growing Watermelon in Atlanta
Atlanta's Zone 7b climate in the Piedmont provides roughly 240 frost-free days. Spring arrives in earnest by late March, giving gardeners an excellent head start on warm-season crops. The hot, humid summers are productive for tomatoes, peppers, and squash but require attention to fungal diseases. Fall gardens starting in late August often outperform spring ones.
In Atlanta (last frost around March 20), aim to direct sow or transplant watermelon outside around April — approximately 2 weeks after your last expected frost. Starting seeds indoors 4 weeks before the last frost date gives you a significant head start.
