Water Chinese hemlock consistently, especially during dry periods, to maintain even soil moisture. Avoid waterlogged conditions, which can lead to root rot.

Allow the top 2-3 cm of soil to dry slightly between waterings for established trees.

Prune Chinese hemlock to remove dead, damaged, or crossing branches. Light pruning can be done in late winter or early spring before bud break. Avoid heavy pruning, as it can stress the tree and affect its natural form.

Shape only as needed to maintain health and structure.

Chinese hemlock can be propagated from seeds sown in autumn or by taking semi-hardwood cuttings in late summer. Seeds require stratification.

Cuttings should be treated with rooting hormone and kept in a moist, well-draining medium in a humid environment.

Repot young Chinese hemlock trees every 2-3 years, or when root-bound, typically in early spring. Use a well-draining potting mix.

For mature trees, repotting is rarely necessary and should only be undertaken if absolutely essential, with careful attention to root disturbance.
