Heisteria acuminata prefers consistently moist soil, but avoid waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry to the touch.

Reduce watering slightly during cooler months, allowing the soil to dry out a bit more between waterings to prevent root rot.

Prune Heisteria acuminata to maintain its desired shape and size, and to remove any dead, damaged, or crossing branches. Light pruning can be done at any time of year, but heavier pruning is best performed in late winter or early spring before new growth begins.

Heisteria acuminata can be propagated from semi-hardwood cuttings taken in summer. Select healthy, disease-free stems, cut them into 10-15 cm lengths, and insert them into a well-draining potting mix.

Keep the cuttings moist and warm, and they should root within a few weeks.

Repot Heisteria acuminata every 2-3 years, or when the plant becomes root-bound. Choose a pot that is one size larger than the current one.

Use a well-draining potting mix, and repot in spring, handling the roots gently to minimize transplant shock. Water lightly after repotting.
