In USDA hardiness zones 3 to 11, warm weather, full sun, and consistent moisture work together for sweet potatoes (Ipomoea batatas) to flourish, but it’s not that easy. These starchy tubers are frost and drought-sensitive. If the sweet potato’s vines freeze, you’ll need to dig up the roots right away. Otherwise, the decay will spoil the entire vegetable. Since healthy roots won’t stop growing, by day 80 in the 90 to 150-day cycle, you should check on your potatoes to ensure it hasn’t overgrown and split open. Plus, you’ll have to deal with pests like sweet potato beetles and wireworms.
