Water regularly to keep the soil consistently moist but not waterlogged. Allow the top layer of soil to dry slightly between waterings. Reduce watering in cooler months. Ensure good drainage to prevent root rot.

Deadhead spent flowers regularly to encourage further blooming and maintain a tidy appearance. Remove any yellowing or damaged leaves. Light pruning can be done after flowering to shape the plant.

Propagate from seeds sown in early spring or autumn. Seeds germinate best in well-draining soil kept consistently moist and at a moderate temperature. Transplant seedlings when they are large enough to handle.

Repot young plants annually or when they become root-bound, typically in spring. Use a well-draining potting mix. Mature plants may only need repotting every 2-3 years, or when signs of distress appear.
