Water regularly, allowing the soil to dry out slightly between waterings. Ensure good drainage to prevent root rot. Reduce watering in winter when the plant is dormant.

Overwatering is a common issue, so err on the side of caution. Check soil moisture with your finger before watering.

Prune after flowering to maintain shape and prevent seeding. Cut back flower stalks to the base of the plant. In late winter or early spring, remove any dead or damaged foliage to encourage new growth.

This also helps to keep the plant tidy and prevent disease.

Propagate by division in spring or autumn. Carefully divide established clumps into smaller sections, each with roots and shoots. Replant divisions immediately into well-draining soil.

Alternatively, propagation can be done by seed, sown in autumn or spring in a cold frame.

Repot young plants annually or as needed, usually in spring, to provide fresh soil and space for root growth. Mature plants can be repotted every 2-3 years. Use a well-draining potting mix.

Ensure the new pot has adequate drainage holes to prevent waterlogging.
