| Horseradish seldom produces seeds, so you'll need to start plants from root cuttings. Space the plants 1' apart, planting 2-4 inches deep. Because the roots can grow several feet deep, prepare the soil well by incorporating organic material like compost or aged-manure into the bed prior to planting. Horseradish needs regular watering, especially in the in the late summer and fall months, when the plants do most of their growing. Horseradish likes full sun (but will tolerate only 4 hours a day-- just produce slower and less roots) and likes at least 1" of water a week during the growing season. It's easy to keep horseradish happy-- just apply a few shovelfuls of composted manure in spring and mulch in summer to keep the soil moisture constant. |
