Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot. Reduce watering in winter to allow the soil to dry out more between waterings.
Ensure good drainage to prevent waterlogging.

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot. Reduce watering in winter to allow the soil to dry out more between waterings.
Ensure good drainage to prevent waterlogging.
Prune to maintain shape and encourage bushier growth. Pinch back the tips of stems regularly. Remove any leggy or overgrown stems.
Pruning can be done at any time, but is most effective in spring before active growth begins.
Easily propagated from stem cuttings. Take 10-15 cm cuttings in spring or summer. Remove lower leaves and plant in moist potting mix. Cuttings root quickly in bright, indirect light, usually within a few weeks.
Mist occasionally to maintain humidity.
Repot every 1-2 years, or when the plant becomes root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one.
Repot in spring, as new growth emerges, to minimize transplant shock.
