Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter, providing only enough to prevent complete desiccation.

Alectryon carinatus prefers well-drained soil and is sensitive to overwatering, which can lead to root rot.

Prune Alectryon carinatus lightly to maintain shape and remove any dead, damaged, or crossing branches. The best time for pruning is after flowering, typically in late spring or early summer.

Avoid heavy pruning, as it can reduce flowering and fruiting.

Propagation is best achieved through semi-hardwood cuttings taken in summer or early autumn. Use a rooting hormone and provide bottom heat in a well-draining potting mix.

Germination from seed is also possible, but can be slow and erratic, requiring patience.

Repot Alectryon carinatus every 2-3 years, or when root-bound, preferably in early spring before new growth begins. Use a well-draining potting mix, such as a blend of potting soil, perlite, and sand.

Ensure the new pot has adequate drainage holes.
