Chinese Chestnut prefers consistent moisture, especially during establishment and fruiting. Water deeply when the top 2-5 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering frequency in cooler months as growth slows.

Prune Chinese Chestnut to shape the tree and remove dead, diseased, or crossing branches. The best time for structural pruning is during dormancy in late winter or early spring.

Summer pruning can be done to manage size and remove water sprouts.

Chinese Chestnut is typically propagated by seed, though grafting is used for specific cultivars. Seeds should be sown fresh in the fall or stratified over winter.

Grafting is usually done in late winter or early spring using scions from desired trees.

Repotting is generally not applicable to mature trees as they are typically planted directly in the ground. For container-grown young trees, repot every 2-3 years into a larger container with well-draining soil, usually in early spring before significant growth begins.
