Water consistently, allowing the top 2-3 cm of soil to dry out between waterings. Avoid overwatering, which can lead to root rot. Reduce watering frequency during winter months when the plant's growth slows down.

Ensure good drainage to prevent waterlogged conditions.

Prune to maintain desired shape and size, and to encourage denser growth. Lightly prune in late spring or early summer after flowering. Remove any dead, damaged, or crossing branches.

Heavy pruning is best done in late winter or early spring before new growth emerges.

Propagate Syzygium buxifolium from semi-hardwood cuttings taken in late summer. Dip the cuttings in rooting hormone and plant them in a well-draining, moist potting mix.

Cover with a plastic bag or propagation dome to maintain high humidity until roots develop.

Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix, preferably one formulated for evergreens or acid-loving plants.

Repot in spring, just before new growth begins, ensuring the new pot is only slightly larger than the current one.
