Bed Preparation

Horseradish grows in moist, silty soils. Space plants 30" apart. Site your horseradish in an out-of-the way spot., because it's hard to move this perennial once its planted.

Planting

Situate horseradish roots diagonally in the soil, with the slanted end down and the flat end up.

Harvest

Allow upright horseradish plants a full season to establish themselves in the garden. The long, strap-like leaves often grow 3 to 4 feet tall; the should not be fed to livestock or people, but make good compost fodder.
