๐ŸŒฑ Zone 5B Planting Guide

USDA Hardiness Zone 5B covers portions of Kansas, Missouri, southern Ohio, and the Colorado foothills, with average annual minimum temperatures between -15ยฐF and -10ยฐF. The growing season averages 178 frost-free days, from a last spring frost around Apr 18 to a first fall frost near Oct 13. With nearly six months of frost-free weather, Zone 5B supports a wide range of vegetables, herbs, and flowers. Succession planting of cool-season crops in both spring and fall is a productive strategy, and most warm-season crops have time to produce two or more flushes.
