Horseradish can be invasive so you may want to isolate it in your garden.
Horseradish thrives in full sun but tolerates light shade. As for soil, horseradish can take almost anything but consistently waterlogged conditions. Site your horseradish in an out-of-the way spot because you won’t want to move this perennial once it is planted. Loosen the soil to 30 cm (12 in) deep and add a shovelful of compost. Plant the root cutting at a 45-degree angle, with the top of the cutting 5 cm (2 in) below the soil line. One plant is usually plenty for a family. If you love horseradish so much that you need more than one plant, space them 70 cm (30 in) apart. To keep the plant from looking ratty, water it once a week during dry spells and use a couple of inches of mulch around the plant to help conserve moisture.`
