Water Heteropterys aenea regularly during the growing season, allowing the soil to dry slightly between waterings.

Reduce watering significantly in winter, providing just enough to prevent the soil from becoming bone dry. Overwatering can lead to root rot, so ensure good drainage.

Prune Heteropterys aenea in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain shape and encourage bushier growth.

Heavy pruning can be done to control size and promote flowering on older wood.

Propagate Heteropterys aenea from semi-hardwood cuttings taken in summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix.

Keep the cuttings moist and warm, and they should root within several weeks. Alternatively, seeds can be sown.

Repot Heteropterys aenea every 2-3 years, or when it becomes root-bound. Spring is the ideal time for repotting.

Use a well-draining potting mix, and choose a pot that is only slightly larger than the current one to avoid waterlogged soil. Water thoroughly after repotting.
