South Dakota USDA Plant Hardiness Map Information
South Dakota is divided into zones, as seen on the South Dakota planting map above, according to average winter extreme temperatures. The USDA collected data over thirty years for their new plant hardiness map that was released in 2023.
South Dakota zones include the chilly regions of 4a, 4b, 5a, and a couple small sections of 5b. With average winter low temperatures possible of -30 degrees F. (-34 C.), gardeners have to pay particular attention to what they plant. To find your location on the South Dakota planting map, you can enlarge the map above. If you need additional information or have trouble finding your zone, you can go to the USDA site and input your zip code. Once you have found your zone, you can use this information to choose shrubs, flowers, and trees that are suitable for your region.
While the information presented in the USDA zone map should serve as foundational tool, it should be considered alongside other factors that influence plant success including, but not limited to, winter sunshine, humidity, wind, and soil type. Although the average winter extreme temperatures in South Dakota can get very cold, many plants will tolerate this extreme weather. Plant these zone appropriate flowers, trees, and shrubs according to their recommended planting instructions and provide regular care for a thriving garden.
