Horseradish
Horseradish is a hardy perennial plant that is normally grown as an annual. This cool-season root crop is not well adapted to Mississippi’s climate and soils.
Start in early spring with root cuttings (sets) that are 8 to 14 inches long. Plant them 18 to 24 inches apart and 4 to 5 inches deep in a trench. Water and mulch to keep soil cool. Horseradish does best in deep, loose, fertile soil. Use a fertilizer high in potash to promote good root development. Keep side shoots removed to force development of one large root. This requires digging around the crown to cut off the side shoots. Harvest in the fall after frost.
Side roots not removed during growth can be removed at harvest, stored, and used to start another crop.
