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 Idaho
Idaho has a semi-arid continental climate. Southern valleys are Zone 6-7 with hot dry summers; northern regions and mountains are colder. Excellent for root vegetables and cool crops.
