Water regularly, allowing the soil to dry slightly between waterings. Avoid waterlogging, which can lead to root rot. In hot, dry conditions, more frequent watering may be necessary to maintain soil moisture.

Reduce watering during cooler periods or when the plant is dormant.

Prune in early spring before new growth begins to shape the plant and remove any dead or damaged stems. Pinch back young plants to encourage bushier growth.

Deadhead spent flowers regularly to promote continuous blooming and prevent self-seeding, which can be aggressive.

Propagate by seeds sown in spring or by softwood cuttings taken in late spring or early summer. Seeds can be sown directly outdoors after the last frost or started indoors a few weeks prior.

Cuttings should be rooted in a well-draining potting mix.

Repot young plants annually in spring as needed, typically when they become root-bound. Mature plants can be repotted every 2-3 years. Use a well-draining potting compost.

Ensure the new pot has adequate drainage holes to prevent water accumulation.
