Eutrema deltoideum prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, which can lead to root rot.

Reduce watering slightly during winter dormancy, but never allow the soil to dry out completely.

Pruning is generally not required for Eutrema deltoideum. Remove any dead or yellowing leaves as they appear to maintain the plant's appearance and health.

Significant pruning is only necessary if the plant becomes leggy or overgrown.

Propagation is typically done by division of rhizomes in early spring before new growth begins. Carefully separate the rhizomes, ensuring each piece has at least one growth bud, and replant them in well-draining soil.

Keep moist until established.

Repot Eutrema deltoideum every 2-3 years, or when it becomes root-bound. The best time for repotting is in early spring before the start of active growth.

Use a well-draining potting mix and a pot only slightly larger than the current one.
