Site: Horseradish likes an open sunny position with light, well dug, rich and moist soil.
Propagation: Start by planting horseradish in the fall or very early spring. Make holes with a dibber about two feet apart. Use root pieces (thongs) that are 1/2" width in diameter and about 6 long. Plant vertically in soil, at a depth of 2 inches.
Growing: Thin out or transplant to 12 inches apart. Do not try growing horseradish indoors. One to three plants will be more than enough for a home garden.
Harvesting: Dig up roots as needed or in October, lift all the plants and store the roots in sand for use and for replanting in spring. Pick young leaves for immediate usage.
Culinary Uses: Young leaves can be used in salads. Roots can be used to make horseradish sauce to accompany roast beef, ham and smoked or oily fish and shellfish. Grate into coleslaw, dips, cocktail sauce, pickled beets, cream cheese, sour cream or avocado fillings. NOTE: Grating horseradish is an unpleasant and eye-watering job - make life easier by using the shredder attachment of a food processor to do the grating for you.
