Where to Plant
Horseradish is a perennial, plant your horseradish into a permanent bed, mark well and never till your horseradish bed. Plant in full 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, as soon as you receive your roots. If the ground can’t be worked store in your refrigerator, loosely wrapped.
How to Plant
Dig a hole about 12” across and about 8-10” deep, loosen the soil, place the root at a 45 degree angle with the top of the root just below the soil surface, holding the horseradish root refill to overflowing to mound up a couple of inches to account for settling. One can refill the hole with compost if it is available.
Watering and Fertilizing
Fertilize and water as you would any garden plants according to need, horseradish needs to be slightly moist. If you are fertilizing your garden you can also fertilize sparingly 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. One year old roots tend to be more pungent and better tasting, so dig or lift plant. 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 it is time to determine which sections to divide. Usually sections that are at least ½ in diameter and at least 6” long work best for you next years 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.
