Dipterocarpus alatus prefers consistently moist soil, especially when young. Water regularly during dry periods, ensuring good drainage to prevent waterlogging.

Allow the top inch of soil to dry out slightly between waterings once established.

Prune to remove dead, damaged, or crossing branches. Light pruning can be done to maintain shape, but avoid heavy pruning as it can stress the tree.

The best time to prune is typically in late winter or early spring before new growth begins.

Propagation is typically done from fresh seeds, which require a period of dormancy. Cuttings are generally difficult to root. Seeds should be sown in a well-draining medium and kept moist in a warm environment.

Young Dipterocarpus alatus may benefit from repotting every 2-3 years in spring to refresh the soil and provide more space for root growth. Use a well-draining potting mix.

Mature trees are best left in their pots or planted directly in the ground.
