Water Astronium lecointei regularly during the growing season, allowing the top 5-7 cm of soil to dry out between waterings.

Reduce watering significantly in winter, providing just enough to prevent the soil from becoming completely dry. Ensure good drainage to avoid waterlogging, which can lead to root rot.

Prune Astronium lecointei to shape and remove any dead, damaged, or crossing branches. Light pruning can be done anytime, but heavier pruning is best done in late winter or early spring before new growth begins.

This promotes a more robust and aesthetically pleasing structure.

Propagate Astronium lecointei from seeds sown in spring or from semi-hardwood cuttings taken in summer. Seeds require warm conditions and consistent moisture for germination.

Cuttings should be rooted in a well-draining medium and kept in a humid environment until established.

Repot Astronium lecointei every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix.

Spring is the ideal time for repotting, allowing the plant to establish itself in its new container before the active growing season. Water lightly after repotting.
