USDA Hardiness Zone 7A covers much of Virginia, Tennessee, the Carolinas, and parts of Oklahoma and New Mexico, with average annual minimum temperatures between 0°F and 5°F. The growing season averages 206 frost-free days, from a last spring frost around Apr 5 to a first fall frost near Oct 28. Nearly seven months of frost-free weather makes Zone 7A suitable for a broad range of crops, including longer-season varieties like sweet potatoes and okra. Summer heat and humidity are the primary management challenges; drip irrigation and disease-resistant cultivars help maintain yields.
