Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering in autumn and winter, allowing the top layer of soil to dry out slightly between waterings.

Ensure good drainage to prevent root rot, especially in containers.

Prune lightly after flowering to remove spent flower stalks and to maintain a tidy appearance. This can also help prevent self-seeding if desired.

Remove any dead or damaged foliage in early spring before new growth begins. Heavy pruning is generally not necessary.

Circaea mollis can be propagated by division of established clumps in spring or autumn. Seeds can also be sown in autumn outdoors or in a cold frame. Germination can be erratic and may take some time.

Seedlings may require vernalization.

Repot container-grown plants every two to three years, or when they become root-bound. Use a well-draining potting mix. Repotting is best done in early spring before new growth commences.

Water thoroughly after repotting to help settle the soil.
