South Carolina Climate Overview
South Carolina offers one of the longest growing seasons in the eastern US. The Lowcountry around Charleston can grow vegetables nearly year-round, while the Upstate around Greenville has a more defined winter. Container gardening is ideal for managing summer heat stress and taking advantage of the extended fall-spring growing seasons.
