Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering in winter to prevent waterlogging. Ensure good drainage to avoid root rot, especially in potted specimens.
Avoid letting the soil dry out completely for extended periods.

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering in winter to prevent waterlogging. Ensure good drainage to avoid root rot, especially in potted specimens.
Avoid letting the soil dry out completely for extended periods.
Prune after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches.
For vigorous plants, hard pruning can be done in late winter or early spring before new growth begins to manage size and encourage flowering.
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 consistently moist and in a warm, humid environment.
Rooting can take several weeks to months.
Repot young plants annually or every two years in spring as they become root-bound. Mature plants can be repotted less frequently. Use a well-draining potting mix.
Ensure the new pot is only slightly larger than the previous one to avoid overwatering issues.
