Armoracia macrocarpa prefers consistently moist soil. Water regularly, especially during dry periods, ensuring the soil does not become waterlogged. Reduce watering in winter when the plant is dormant.

Check the soil moisture by feeling the top few centimeters before watering.

Pruning is generally not required for Armoracia macrocarpa unless removing dead or damaged foliage. If the plant becomes overgrown, it can be divided in early spring or late autumn.

Cut back any withered leaves or flower stalks to maintain a tidy appearance.

Armoracia macrocarpa is easily propagated by root cuttings or division. In early spring, take sections of healthy roots, ensuring each has at least one bud, and plant them horizontally in moist potting mix.

Division of established clumps in early spring or fall also works well.

Repotting is typically only necessary when the plant becomes pot-bound or if the soil needs refreshing. This is best done in early spring before new growth begins.

Choose a pot that is only slightly larger than the current one to avoid excessive moisture retention.
