Water deeply and regularly, especially during dry periods. Allow the top 2-3 cm of soil to dry out between waterings. Avoid waterlogging, which can lead to root rot. In containers, ensure good drainage.

Prune in late winter or early spring. Cut back the previous year's growth to about 20-30 cm from the ground. This encourages vigorous new growth and abundant flowering on the current year's stems.

Propagate from seed sown in autumn or spring. Softwood cuttings can be taken in early summer. Layering is also an effective method, typically performed in late summer or early autumn.

Repot young plants annually in spring to ensure healthy root development. Mature plants can be repotted less frequently, perhaps every 2-3 years. Use a good quality, well-draining potting mix.
