Planchonella arnhemica prefers consistently moist soil but can tolerate short dry spells. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering slightly during cooler months or if the plant is in a dormant state.

Prune Planchonella arnhemica to maintain its shape or remove dead, damaged, or crossing branches.

Light pruning can be done any time, but heavier pruning is best performed in late winter or early spring before new growth begins. Use clean, sharp tools to make precise cuts.

Propagation of Planchonella arnhemica is typically done by seeds or stem cuttings. Seeds should be sown in a well-draining seed-starting mix and kept moist and warm.

Stem cuttings can be taken during the growing season, dipped in rooting hormone, and planted in a suitable medium.

Repot Planchonella arnhemica every 2-3 years or when it becomes root-bound. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix, such as a blend of potting soil, perlite, and sand. Repotting is best done in spring.
