Water Brucea macrocarpa moderately when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. Ensure good drainage in pots.

Reduce watering frequency during cooler winter months to prevent waterlogged conditions, allowing the soil to dry out slightly more between waterings.

Prune Brucea macrocarpa to maintain desired shape and size, and to remove any dead, damaged, or crossing branches.

Light pruning can be done year-round, but heavier pruning is best performed in late winter or early spring before new growth emerges. This encourages bushier growth and better air circulation.

Brucea macrocarpa can be propagated from semi-hardwood cuttings taken in summer or hardwood cuttings taken in winter. Insert cuttings into a well-draining rooting medium and keep moist.

Alternatively, propagation can be attempted from seed, though this may take longer and result in variable offspring. Rooting hormone can improve success rates.

Repot Brucea macrocarpa every 2-3 years, or when the plant becomes root-bound. Choose a pot only slightly larger than the current one, with adequate drainage holes. Use a well-draining potting mix.

Repotting is best done in spring, coinciding with the start of the active growing season, to minimize transplant shock.
