USDA Hardiness Zone 8B covers coastal Georgia, northern Florida, southern Louisiana, and the Texas Gulf Coast, with average annual minimum temperatures between 15ยฐF and 20ยฐF. The growing season extends to approximately 251 frost-free days, from a last spring frost around Mar 12 to a first fall frost near Nov 18. With over eight months of frost-free weather, Zone 8B supports warm-season crops from early spring through late fall. Heat-tolerant varieties and consistent irrigation are essential during the long, humid summers; fall planting of cool-season crops extends production well into winter.
