HORSERADISH:
Planting Horseradish Roots
CULTURE: This pungent, deep-rooted perennial is one of the easiest garden vegetables to grow. It prefers well-dug soil rich in organic matter. It also spreads easily, so you may want to isolate it. Apply 1–1 ½ pounds of our complete fertilizer per 20 square feet. Mix the fertilizer into the top 3–4 inches of soil. Dig a shallow trench and place the roots in the trench horizontally, spacing them 1–2 feet apart and cover with 2 inches of soil. You’ll harvest larger roots if the plants are kept well watered throughout the summer.
INSECTS AND PESTS: None that we know of. Contact your county agent with specific questions.
HARVEST: Dig the roots in the fall after the tops have frosted. Replant some of the smaller roots then, and harvest the larger roots for use in the kitchen. Store the harvested roots in the refrigerator in a plastic bag. Wash, trim, and grate. Add vinegar or lemon juice to keep the chopped root from turning brown.
