Water moderately when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot. Ensure good drainage in pots and garden beds. Reduce watering during winter dormancy to prevent waterlogged roots.

Prune after flowering to maintain a tidy shape and encourage bushier growth. Remove dead or spent flower stalks.

Light pruning can also be done in late winter or early spring to remove any winter damage and shape the plant before new growth begins.

Propagate from seeds sown in spring or autumn. Seeds can be sown directly into the garden bed or started indoors. Cuttings taken in late spring or early summer can also be used.

Ensure cuttings have a few leaves and are planted in well-draining soil.

Repot young plants annually or biennially in spring. Mature plants generally do not require frequent repotting and prefer to be slightly pot-bound.

Use a well-draining potting mix and a pot that is only slightly larger than the current one.
