Water
Water thoroughly when the top 2-3 cm of soil feels dry. Allow the soil to dry out slightly between waterings. Avoid waterlogging, as this can lead to root rot.
Reduce watering significantly during cooler months or when the plant is dormant.

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Allow the soil to dry out slightly between waterings. Avoid waterlogging, as this can lead to root rot.
Reduce watering significantly during cooler months or when the plant is dormant.
Prune in late winter or early spring to shape the plant and remove any dead, damaged, or crossing branches. This encourages bushier growth and can control its size. Heavy pruning can rejuvenate older plants.
Easily propagated from stem cuttings taken in spring or summer. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep moist and warm. Seeds can also be sown in spring, but cuttings are faster.
Repot young plants annually or when root-bound, typically in spring. Mature plants can be repotted every 2-3 years or when drainage becomes an issue. Use a well-draining potting mix and a pot with drainage holes.
