Water
Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot. Reduce watering slightly during the cooler, dormant months to prevent over-saturation.
Ensure good drainage to maintain healthy roots.

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot. Reduce watering slightly during the cooler, dormant months to prevent over-saturation.
Ensure good drainage to maintain healthy roots.
Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead or crossing branches. Heavy pruning is generally not necessary unless the plant has become overgrown.
This helps to promote better air circulation.
Propagate from semi-hardwood cuttings taken in summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix.
Keep the cuttings moist and warm, and provide them with bright, indirect light until they root.
Repot every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.
Repot in spring before the active growing season begins to minimize stress.
