About Peanut
Peanuts are a fascinating crop — not a tree nut but a legume that flowers above ground and buries its pods below. They need a long, hot growing season and loose, sandy soil.
Plant raw, unroasted peanuts after soil warms to 65°F+. Hill soil around plants as they grow so pegs can bury. Harvest when foliage yellows; dry the pods before shelling.
Gardening in Maine
Maine has a cool humid continental climate. Coastal areas are Zone 5b-6a; inland and northern Maine is Zone 3b-4a. Short summers but excellent for potatoes, blueberries, and cool crops.
