Water consistently when the top inch of soil feels dry, especially during dry periods. Dahurian larch prefers moist, well-drained soil and can tolerate some drought once established.

Avoid waterlogged conditions which can lead to root rot. Reduce watering in winter when the plant is dormant.

Prune in late winter or early spring before new growth starts. Remove dead, damaged, or crossing branches to maintain the tree's natural shape and improve air circulation.

Light pruning can be done after flowering to shape the tree or control size. Avoid heavy pruning.

Propagate from seeds sown in autumn or after a period of cold stratification. Cuttings can be taken from semi-hardwood in summer, but they can be challenging to root.

Grafting is also a common method for cultivars, typically performed in late winter.

Young trees can be repotted every 2-3 years in early spring, while mature trees rarely need repotting. Use a well-draining potting mix.

Ensure the root ball is loosened gently and that the tree is replanted at the same depth. Repotting is primarily for container-grown specimens.
