Horseradish is a vigorous, easy-to-grow perennial root vegetable that prefers full sun to partial shade and moist, fertile soil. Plant in a contained bed as it spreads readily and can become difficult to control. Harvest roots in autumn for the best pungent flavor, and keep foliage trimmed to direct energy into root production.
