Water Armoracia sisymbrioides regularly, keeping the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out slightly between waterings, especially during warmer months.

Reduce watering in winter when the plant's growth slows down to prevent root rot.

Pruning is generally minimal for Armoracia sisymbrioides. Remove any dead, damaged, or diseased foliage as needed throughout the growing season.

If the plant becomes overgrown or sprawled, you can cut it back in late autumn or early spring to maintain a tidy shape.

Armoracia sisymbrioides is primarily propagated by root cuttings or division. In early spring, carefully dig up the plant and divide the root system into sections, ensuring each piece has at least one bud.

Replant the sections immediately into well-draining soil.

Repot Armoracia sisymbrioides every 2-3 years, or when the plant becomes pot-bound. Spring is the ideal time for repotting.

Choose a pot that is slightly larger than the current one, and use a well-draining potting mix, preferably one enriched with compost.
