Armoracia rusticana. Easy to grow perennial. Horseradish is a widely-adapted, hardy perennial producing roots that are ground or finely shredded to make wonderfully hot and sweet sauces and condiments. Horseradish root can be harvested in late fall or early spring. Dig in the fall after a hard frost for sweeter flavour, or before the plant leafs out in the spring for maximum pungency. Roots should be divided and replanted every 2 years to prevent them from becoming woody. Horseradish spreads easily so you may want to isolate it in your garden. No. 1 root.

Important! Upon Arrival:
Keep moist and cool. Fruits and berries are shipped in dormant form so they can be transplanted out once the soil can be worked in the spring. Light frosts will not damage the plants as they are in the resting stage. If you are unable to plant immediately, the plants can be stored for a short period of time. This should be a dark, cool (but not freezing) location such as an unheated garage, fridge or a cold cellar. They should also be kept moist, but not wet, until they are planted.
Horseradish is a long-lived perennial which requires little care. It prefers a fertile, well-drained soil with a pH between 6.0 to 7.5. Pick a sunny location, Dig a hole deep and wide enough to allow the roots to spread. Place the root at a 45° angle in the hole, with the flat end up, 2” below soil surface, Cover with soil and water well. Space roots 1 to 2 feet apart in rows 2.5 to 3 feet apart. Do not fertilize at time of planting. You should provide temporary shade to allow the roots to recover from transplanting. Wait until the leaves appear before applying the first application of a well-balanced fertilizer such as 10-10-10.
When planting horseradish in pots, choose a pot that has drainage holes and is deep enough to encourage root growth (24-36 inches deep). Although horseradish is cold hardy, plant your container grown root after all danger of frost has passed or start it indoors.
Horseradish needs about a year to produce a crop and the crown should be at least 1-inch in diameter before you harvest. You can harvest in late fall when the leaves have been killed by frost or early spring as the crown is just starting to show some green growth. To harvest, dig down around the plant as far as you can and then gently lift the root out of the ground. Break of some of the smaller roots and plant in the ground. Cover with soil and fertilize. The rest of the horseradish can be processed. If you do not harvest the roots, you should divide the plants every year or two. Pruning is not necessary. Horseradish is quite drought-tolerant. If under watered, roots become woody and have a weak flavour. If over watered, roots become very soft and have a strong flavour. Water once a week, 1-2 inches.
Horseradish is in the same family as broccoli and cabbage, so be prepared for the same host of insect pests as you find with these other vegetables. Cabbage worms and loopers can be controlled using BTK, Rotenone or Pryrethrum.
