Lithocarpus pachyphyllus prefers consistent moisture but dislikes waterlogged soil. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering slightly during winter dormancy, allowing the soil to dry out a bit more between waterings. Ensure good drainage to prevent root rot.

Prune Lithocarpus pachyphyllus primarily to maintain shape, remove dead or damaged branches, and improve air circulation.

Light pruning can be done anytime, but heavier structural pruning is best done in late winter or early spring before new growth begins. Use clean, sharp tools.

Propagation is typically done by sowing fresh seeds. Scarify or stratify seeds according to specific requirements for Lithocarpus species to improve germination rates.

Grafting may also be an option for specific cultivars, though it is less common for general propagation. Patience is key as germination can be slow.

Young Lithocarpus pachyphyllus plants may benefit from repotting every 2-3 years to refresh the soil and provide more space for root growth.

Mature trees generally do not require repotting and are better left undisturbed. Use a well-draining potting mix when repotting.
