Cariniana legalis prefers consistently moist soil but dislikes waterlogging. Water deeply when the top few centimeters of soil feel dry, especially during warmer months.

Reduce watering frequency in cooler periods, allowing the soil to dry out slightly more between waterings to prevent root rot.

Pruning is generally minimal for Cariniana legalis, primarily focused on removing dead, damaged, or crossing branches. Prune in late winter or early spring before new growth begins.

This helps maintain the tree's natural shape and health. Avoid heavy pruning, as it can stress the plant.

Propagation is typically done through seeds, which require stratification. Sow seeds in a well-draining, moist medium and keep them warm.

Cuttings are more challenging but can be attempted from semi-hardwood material taken in summer, using rooting hormone and providing high humidity.

Young plants may benefit from repotting every 2-3 years into slightly larger containers. Use a well-draining potting mix. Mature trees rarely need repotting and are often best left undisturbed in their location.

Repotting is best done in spring before the start of active growth.
