Water Pleroma urvilleanum regularly, keeping the soil consistently moist but not waterlogged, especially during its active growing season. Reduce watering in winter, allowing the top few centimeters of soil to dry out between waterings to prevent root rot.

Prune Pleroma urvilleanum after flowering to maintain its shape and encourage bushier growth. Remove any dead, damaged, or crossing branches. Heavy pruning can be done in early spring before new growth begins.

Propagate Pleroma urvilleanum from semi-hardwood cuttings taken in late summer. Dip cuttings in rooting hormone and plant them in a well-draining potting mix. Keep consistently moist and warm, ideally with bottom heat.

Repot Pleroma urvilleanum every 2-3 years, or when it becomes root-bound, preferably in early spring. Use a well-draining potting mix, and choose a pot that is only slightly larger than the current one to avoid waterlogged roots.
