About Horseradish
Horseradish is a vigorous, nearly indestructible perennial grown for its pungent taproot — the fresh stuff blows store-bought away. Plant it where you want it to stay.
Plant root cuttings in spring, burying on a slight angle. Harvest roots in fall after a few frosts for best heat. It spreads — contain it in a pot or dedicated bed.
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.
