Cnidium monnieri prefers consistent moisture, especially when young. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly in cooler weather or during dormancy, but do not let the soil become completely dry.

Prune back to the ground in late autumn or early spring before new growth begins. This tidies the plant and removes any dead or damaged stems.

Deadheading spent flower stalks can encourage a second flush of blooms in some conditions, but is not strictly necessary.

Cnidium monnieri is typically propagated by seed or division. Sow seeds in early spring, either directly outdoors or started indoors a few weeks prior.

Division of established clumps can be done in spring or autumn, ensuring each division has healthy roots and shoots.

Repotting is generally only necessary for container-grown plants when they become root-bound, typically every 2-3 years. Choose a pot that is one size larger than the current one.

Repot in spring before active growth begins, using a well-draining potting mix.
