How to Grow Horseradish

People tend to have strong feelings about horseradish: Either they loathe the stuff, or they can't imagine a roast beef sandwich without it. If you fall into the latter camp, here's good news: This hardy perennial herb is a cinch to grow from USDA zone 3 south.

Instructions

- 1
  Buy plants or roots at the nursery (horseradish is rarely, if ever, grown from seed) for planting after the last frost in spring.
- 2
  Choose a site for location rather than growing conditions - a spot far removed from any other plants you care about. Left to its own devices, horseradish will stampede through your garden faster than you can say "Hi-ho, Silver!" But it will grow in any circumstances except deep shade or constant wetness.
- 3
  Ensure the straightest, plumpest roots by tilling the soil to at least 12 inches, amending it with plenty of compost and removing all rocks and other obstructions.
- 4
  Set plants or roots 9 to 18 inches apart, with the crown (the top of the root and the start of the top growth) about 4 inches below the soil surface, and water thoroughly.
- 5
  Mulch to retain moisture and discourage weeds if you want to, but it's not necessary - horseradish thrives on neglect.
- 6
  Dig horseradish roots anytime from midsummer on, but for best flavor wait until after the first frosts.
