African Walnut prefers consistently moist soil but dislikes waterlogging. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering slightly during cooler months, but never allow the soil to dry out completely. Ensure good drainage to prevent root rot.

Prune African Walnut primarily to maintain shape, remove dead or diseased branches, and improve air circulation.

Light pruning can be done anytime, but major shaping should occur in late winter or early spring before new growth begins. Avoid excessive pruning, as it can stress the plant.

African Walnut is typically propagated by seeds, which require stratification for best germination. Cuttings can also be taken from semi-hardwood in summer.

Ensure cuttings are treated with rooting hormone and kept in a humid environment. Germination can be slow and erratic.

Repot young African Walnut trees every 1-2 years in spring, or when root-bound. Use a well-draining potting mix. Mature trees require less frequent repotting, perhaps every 3-5 years, or when drainage becomes an issue.

Choose a pot only slightly larger than the current one.
