- Choose a location: Horseradish prefers full sun, but will tolerate partial shade, and well-drained soil. It is also a hardy plant that can withstand cold temperatures.
- Prepare the soil: Horseradish roots prefer a rich, fertile soil with a pH between 6.0 and 7.5. Before planting, amend the soil with compost or well-rotted manure to improve fertility.
- Plant the roots: Plant the horseradish roots in a well-drained spot in your garden, with the crowns about 2 inches below the soil surface and 2-3 feet apart. Space the rows about 3-4 feet apart.
- Fill in the hole: Fill in the hole with soil, making sure not to cover the tips of the roots. Horseradish will spread by underground runners, so be mindful of the plant's placement in your garden.
- Watering: Horseradish prefers consistent moisture, but can tolerate periods of drought. Water the soil deeply, but not too often, to prevent waterlogging.
- Fertilize: Horseradish is a hardy plant and does not require much fertilizer. An all-purpose, granular fertilizer can be applied in early spring, before new growth begins.
- Mulch: Mulch around the horseradish plants to conserve moisture and suppress weed growth. Use a 2-3 inch layer of organic material, such as leaves or straw.
- Harvest: Wait until the second growing season to harvest your horseradish. Carefully dig the roots and remove any leaves. Wash and peel the roots to reveal the pungent flesh. Horseradish can be grated and used fresh or preserved in vinegar for later use.
