Lithocarpus attenuatus prefers consistent moisture, especially when young. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering frequency during cooler months when the plant's growth slows.

Pruning is typically minimal and focuses on removing dead, damaged, or crossing branches. This can be done in late winter or early spring before new growth begins.

Heavy pruning is generally not recommended as it can stress the tree.

Propagation of Lithocarpus attenuatus is most successfully done from seed. Seeds should be sown fresh after collection, as they can lose viability quickly.

Stratification may be required depending on the specific provenance of the seeds. Cuttings are generally difficult to root.

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

Mature trees in the ground rarely require repotting.
