Water regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings to prevent root rot.

Reduce watering in winter months when the plant's growth slows down.

Deadhead spent flowers regularly to encourage more blooms and maintain a tidy appearance. Lightly prune in late autumn or early spring to remove any dead, damaged, or weak stems.

Avoid heavy pruning, which can stress the plant.

Easily propagated from seed sown in spring. Seeds can be sown directly outdoors after the last frost or started indoors a few weeks prior.

Softwood cuttings can also be taken in late spring or early summer and rooted in moist, well-draining soil.

Repot young plants annually or as needed when they become root-bound, typically in spring. Mature plants can be repotted every two to three years.

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