Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in winter to prevent waterlogged roots. Ensure good drainage to avoid root rot, especially in containers.

Overwatering is a common issue, so err on the side of caution.

Prune lightly after flowering to maintain a tidy shape and encourage bushier growth. Remove any dead or straggly stems at any time. Heavy pruning is usually not necessary unless the plant has become overgrown or damaged.

Deadheading spent flowers can also improve appearance.

Propagate by taking stem cuttings in late spring or early summer. Cuttings should be rooted in a well-draining, sandy compost. Alternatively, seeds can be sown in autumn or early spring.

Division of established clumps is also an effective method for propagation.

Repot container-grown plants every 2-3 years, preferably in spring, to refresh the soil and accommodate root growth. Use a gritty, well-draining potting mix. Ensure the new pot has drainage holes.

Avoid disturbing the roots excessively during the repotting process.
