Early spring when the ground is tillable, mix in rich humus or cow manure to your soil. Horseradish loves well rotted compost. You can also add a 10-10-10 fertilizer, but follow the directions closely so it's evenly distributed. Till your soil with compost/fertilizer about 10 inches deep. When planting your horseradish, use well drained moist soil. Growing on a raised bed of 6 to 8 inches works best. Space the horseradish sets 12 to 18 inches width apart. Plant them 2 to 4 inches deep in the soil. Try angling the horseradish sets so that they are at a 30 to 45 degree angle to promote growth. Applying mulch around your plant will allow it to retain moisture and keep the weeds down. The horseradish plant will need to be watered to a depth of 4 to 5 inches weekly. Harvest in the fall or following spring. During the summer you can use the horseradish leaves for salads. During the fall, dig up after the leaves have died back.
