Horseradish Planting Instructions
Where to Plant

Horseradish is a perennial, so plant it in a permanent bed, mark the roots well and never till the soil after planting. Plant in full sun, although horseradish can tolerate partial shade, but growth will be slowed and yield will be reduced.

When to Plant
Plant your Horseradish as soon as you can work the soil in your garden in spring, as soon as possible after you receive your roots. If the ground can’t be worked yet, store the roots in your refrigerator, loosely wrapped.

How to Plant
Dig a hole about 12” across and about 8-10” deep, loosen the soil, and place the root at a 45 degree angle with the top of the root just below the soil surface, holding the horseradish root  while refilling the hole to overflowing, mounding the soil up a couple of inches to account for settling. Add compost to the refill soil if it is available.

Watering and Fertilizing
Fertilize and water as you would any garden plants. Horseradish likes to be slightly moist at all times. If you are fertilizing your garden you can also sparingly fertilize your horseradish.

Horseradish tastes best after a hard frost. After the first hard frost in the fall or in the south in late fall dig your roots. With spade or fork loosen soil and lift the entire root system.

How to Divide and Replant
Wash and dry each root system. If you would like to replant some roots for next year, now is the time to determine which sections to divide. Usually sections that are at least ½ in diameter and at least 6” long work best for next year's crop. Cut the top of the root off square, and trim the bottom of the root at an angle, to remember which end goes down. Plant next years crop as soon as possible after harvest.
