A Field Guide for Maine Growers

Maine Backyard Gardening

Frost dates are regional estimates, partly cross-checked against Old Farmer's Almanac station data and the USDA Plant Hardiness Zone Map; weather and growing-degree data come live from NOAA and Open-Meteo. For your exact town, UMaine Cooperative Extension's own frost-date tool is the authority — none of this replaces what your own soil tells you.
