What changed in Arkansas since 2012
Every ZIP on both mapsCompared ZIP by ZIP from the 2023 and 2012 USDA tables; 691 Arkansas ZIP codes appear in both.
Why Arkansas’s zones moved
Of the cities above, Fayetteville went from 6b to 7a, Fort Smith went from 7b to 8a, Jonesboro went from 7b to 8a, Texarkana went from 8a to 8b and Hot Springs went from 7b to 8a.
The USDA explains the national picture: “When compared to the 2012 map, the 2023 version reveals that about half of the country shifted to the next warmer half zone, and the other half of the country remained in the same half zone.” The new map uses 1991 to 2020 and more than 13,000 weather stations, so it draws Arkansas’s hills, valleys and cities more finely than the 2012 map did.
A warmer zone changes which perennials and shrubs come through the winter, not when the garden gets planted; that still follows the frost dates.
