USDA Hardiness Zone 6B stretches across parts of Kentucky, Virginia, southern Pennsylvania, and central Missouri, with average annual minimum temperatures between -5ยฐF and 0ยฐF. The growing season extends to approximately 193 frost-free days, from a last spring frost around Apr 10 to a first fall frost near Oct 20. This is one of the more forgiving transitional zones: warm-season and cool-season crops both perform well, and the late October frost date gives fall gardens a substantial runway for brassicas, root vegetables, and overwintering garlic.
