Water regularly, especially during dry periods, to maintain consistently moist soil. Avoid waterlogged conditions, which can lead to root rot. Reduce watering in winter when the plant is dormant.

Check the top few centimeters of soil; if dry, it's time to water.

Prune back dead or spent flower stalks after blooming to encourage a tidier appearance and potentially a second flush of flowers.

In late winter or early spring, cut back any weak or overgrown stems to maintain shape and vigor. Remove any dead or damaged foliage.

Propagate by seed sown in spring, or by division of established clumps in early spring or autumn. Softwood cuttings can also be taken in late spring or early summer.

Ensure cuttings are kept moist and in a warm environment for successful rooting.

Repot young plants annually in spring to provide fresh soil and more space. Mature plants can be repotted every 2-3 years or when root-bound. Use a well-draining potting mix.

Ensure the new pot is only slightly larger than the previous one to avoid overwatering issues.
