Horseradish is a hardy perennial that will survive winter even in very cold climates.

Usually horseradish should be planted by itself but is useful at the corner of a potato patch as it has a repellant effect on Colarado Potato Beetles.


Single Plants: 1' 1" (35cm) each way (minimum)

Sow and Plant

Set out roots any time that the ground is not frozen, preferably from early spring to early summer.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.


Persistent and long lived, horseradish can become invasive if you accidentally allow pieces of root to be spread around the garden.


Dig roots anytime you need them in the kitchen. Keep scrubbed roots in the refrigerator.


Horseradish seldom has problems with insects or diseases.
