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.
