Keep the soil consistently moist, as Saururus chinensis thrives in wet conditions. Water thoroughly when the top layer of soil begins to dry out.

Avoid letting the plant sit in stagnant water for prolonged periods, but do not allow the soil to dry out completely. This plant is well-suited for bog gardens or water features.

Prune to maintain desired shape and size, and to remove any dead or damaged foliage. This can be done in late spring after flowering or in early fall. Pinch back stems to encourage bushier growth if needed.

Minimal pruning is generally required for this plant.

Saururus chinensis can be easily propagated by division of rhizomes in spring. Simply dig up the plant and separate the root mass into smaller sections, ensuring each section has at least one bud.

Replant divisions immediately into moist soil.

Repotting is generally only necessary when the plant becomes root-bound or if it is being moved to a new location, such as a bog garden. This is best done in early spring before new growth begins.

Use a well-draining potting mix if grown in a container, and ensure it is placed in a suitable moist environment.
