Planting and Growing Guide for Horseradish (Armoracia rusticana)
Description
Horseradish is grown from root cuttings. Dig a deep hole and place compost or animal manure in the base, back fill with soil and place the horseradish root a little below the surface. Best planted in in early Autumn (Fall) or Spring. Horseradish has a long taproot and so it needs deep, fertile soil. Beware that horseradish can grow and spread prolifically and can out compete other things in your garden if left as a perennial. Dig up the entire plant when harvesting, retaining several pieces to replant in the next season.
Plant Horseradish roots or crowns a few weeks before your last frost date. It is not fussy and so any fertile, well-drained soil will suffice, provided it is deep enough for the roots to grow. Horseradish prefer a neutral to slightly acid pH.
Horseradish has a strong spicy flavor and is used to make a variety of sauces, especially for roast beef. It is also used in stir fry dishes, stews, soups and vegetables dishes.
