Water regularly, especially during dry periods, to keep the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings. Reduce watering in cooler months.

Good drainage is crucial to prevent root rot.

Prune to shape the tree and remove any dead, damaged, or crossing branches. Light pruning can be done after flowering to encourage bushier growth.

For fruit production, specific pruning techniques may be applied after harvest.

Propagate Syzygium smithii from fresh seeds, which require stratification for germination. Cuttings can also be taken from semi-hardwood during late summer or early autumn. Rooting hormone can improve success rates.

Young plants benefit from repotting every 1-2 years in spring. Mature plants require less frequent repotting, typically every 3-5 years. Use a well-draining potting mix.

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