Horseradish

Horseradish makes straighter, easier-to-dig roots in deep, loose loam with a pH around 6.0-7.5. Work in compost before planting, avoid heavy nitrogen feeding, and contain the roots because even small pieces can regrow.

Tips

• Plant root cuttings in spring at a slant, with the upper end about 2 inches below the surface.
• Water the establishing plants deeply when the top inch of soil dries, especially during summer drought.
• Use a soil test to guide fertilizer, since excess nitrogen encourages leaves rather than thick roots.
• Watch for flea beetle damage on young leaves and remove nearby brassica weeds.
• Let plants grow through their first season, then dig roots after fall frost and remove leftover fragments to limit spread.

Plant healthy root cuttings in early spring as soon as the soil is workable.
