Water regularly, ensuring the soil is consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings.

Reduce watering during cooler months, especially if grown outdoors in a mild climate. Overwatering can lead to root rot.

Prune to maintain shape and remove any dead or damaged stems. After flowering, you can deadhead spent blooms to encourage further flowering or prevent seed formation if undesired.

Pruning in late winter or early spring before new growth emerges is also beneficial.

Propagation is typically done by seed, sown in spring. Germination can be slow and may require stratification. Alternatively, root cuttings can be taken in late spring or early summer.

Ensure cuttings are taken from healthy, non-flowering stems.

Repot young plants annually in spring. Mature plants can be repotted every 2-3 years, or when root-bound. Use a well-draining potting mix.

Ensure the new pot is only slightly larger than the previous one to avoid overwatering issues.
