USDA Hardiness Zone 7B includes parts of North Carolina, Arkansas, northern Georgia, and the southern Appalachian foothills, with average annual minimum temperatures between 5°F and 10°F. The growing season extends to approximately 220 frost-free days, from a last spring frost around Mar 28 to a first fall frost near Nov 3. With over seven months of warm weather, Zone 7B supports two full planting cycles for many crops. Fall gardening is particularly productive here — cool-season vegetables planted in late summer thrive through November.
