Water thoroughly when the top 2-3 cm of soil feels dry. Allow excess water to drain away to prevent waterlogging.

Reduce watering frequency during winter dormancy, only providing enough to keep the soil from drying out completely. Overwatering can lead to root rot.

Prune after flowering to maintain a tidy shape and encourage a second bloom. Remove spent flower stalks to prevent self-seeding, unless desired. Cut back leggy or overgrown stems to the base of the plant.

Light pruning can also be done in early spring.

Easily propagated from seed sown in autumn or early spring. Can also be propagated by cuttings taken in late spring or early summer. Root cuttings in a well-draining potting mix.

Seedlings may require a period of cold stratification for germination.

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

Avoid disturbing the roots excessively during repotting.
