Water Macropsychanthus coriaceus thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, which can lead to root rot.

Reduce watering frequency during the dormant winter months, allowing the soil to dry out more between waterings to mimic its natural habitat.

Prune Macropsychanthus coriaceus to maintain shape and remove any dead or leggy stems. Light pruning can be done year-round, but heavier pruning is best performed in late spring or early summer after flowering to encourage bushier growth and new blooms.

Propagate Macropsychanthus coriaceus by stem cuttings taken in late spring or early summer. Dip the cut end in rooting hormone and plant in moist, well-draining potting mix.

Maintain high humidity and consistent warmth until roots develop.

Repot Macropsychanthus coriaceus every 2-3 years or when it becomes root-bound, preferably in spring before new growth begins. Use a well-draining potting mix.

Choose a pot only slightly larger than the previous one to avoid waterlogging.
