Growing Sweet Potatoes in Georgia's Climate
Georgia's moderate Zone 7b climate is well-suited to sweet potato with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your sweet potato harvest significantly in Georgia. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common sweet potato pests to watch for in Georgia include Sweet Potato Weevil and Wireworm. The first line of defense is companion planting: Bush Bean and Pea planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.
