Baccaurea courtallensis prefers consistently moist soil but dislikes waterlogged conditions. Water deeply when the top 2-3 cm of soil feels dry. Reduce watering slightly during cooler, less active periods.

Ensure good drainage to prevent root rot.

Prune to maintain desired shape and size, and to remove any dead, damaged, or crossing branches. Light pruning can be done after fruiting. Avoid heavy pruning as it can stress the plant and reduce fruit production.

Propagation is typically done through seeds or air-layering. Seeds need to be sown fresh.

Air-layering involves creating a wound on a stem, applying rooting hormone, and covering with moist sphagnum moss until roots form, then detaching.

Young plants may need repotting every 1-2 years, while mature plants are less frequently repotted. Choose a pot that is slightly larger than the current one with excellent drainage.

Repot in spring before new growth begins.
