Updated Frost Date Maps

Plantmaps has updated First/Last Frost date maps for all US states in the Continental US. These updated maps use data from NCDC from the period of 1991 to 2020. We’ve also added a new map for each state that displays the average number of days with frost. Each map page also contains a listing of cities and towns with their respective last/first frost dates. A complete list of all Frost data map products can be found here.
