Meliosma allenii prefers consistently moist soil. 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 cooler winter months but never allow the soil to dry out completely.

Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain the plant's structure and health.

Light pruning can be done after flowering to shape the plant and encourage bushier growth.

Propagation is best achieved through semi-hardwood cuttings taken in summer. Use a rooting hormone and plant in a well-draining medium. Maintain high humidity and warmth until roots develop.

Seed propagation is also possible but can be slow and less reliable.

Repot young plants every 2-3 years, or when rootbound. Mature plants may only need repotting every 4-5 years. Use a well-draining potting mix. Repot in spring before active growth begins.

Ensure the new pot is only slightly larger than the previous one.
