Water Crescentia mirabilis thoroughly when the top 2-3 cm of soil feels dry. Reduce watering in winter to prevent waterlogging, as it prefers slightly drier conditions during its dormant period.

Ensure good drainage to avoid root rot.

Pruning is generally minimal for Crescentia mirabilis, focusing on removing dead, damaged, or crossing branches to maintain shape and air circulation. Light pruning can be done after flowering to encourage bushier growth if desired.

Propagation of Crescentia mirabilis is typically done from seeds sown in spring or summer. Seeds may require scarification or soaking before sowing.

Softwood cuttings can also be taken in spring, rooted in a well-draining medium.

Repot Crescentia mirabilis every 2-3 years, or when root-bound, preferably in spring. Use a well-draining potting mix. Choose a pot slightly larger than the current one to accommodate root growth. Avoid overpotting.
