Water regularly, especially during dry spells, but allow the soil to dry slightly between waterings. Overwatering can lead to root rot. Ensure good drainage to prevent waterlogging.

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

Deadhead spent flowers regularly to encourage more blooms and maintain a tidy appearance. Prune back plants in late autumn or early spring to encourage bushier growth and remove any dead or damaged stems.

This also helps to rejuvenate the plant.

Easily grown from seed sown in spring or autumn. For cuttings, take softwood cuttings in late spring or early summer and root them in moist potting mix. Seeds germinate best with warmth and light.

Repot young plants annually in spring or as needed when they become root-bound. Use a well-draining potting mix. Mature plants may not require frequent repotting, but refreshing the top layer of soil can be beneficial.
