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.
