Water consistently during the growing season, especially when young. Allow the soil to dry slightly between waterings. Reduce watering in fall as growth slows.

Ensure good drainage to prevent waterlogged roots, which can lead to root rot. Monitor soil moisture to avoid over or under-watering.

Prune to shape, remove dead or damaged branches, and improve air circulation. The best time for major pruning is late winter or early spring before new growth emerges.

Light pruning for aesthetic purposes can be done throughout the growing season. Avoid heavy pruning of established trees.

Propagation is typically done through grafting, especially for specific cultivars. Seed propagation is possible but may not result in true-to-type offspring.

Collect seeds in fall and stratify them over winter before sowing in spring. Grafting is preferred for predictable results.

Repot young larches every 2-3 years in early spring before new growth begins. For mature trees, repotting is rarely necessary. Ensure the new pot provides ample space for root growth and has excellent drainage.

Use a well-draining potting mix formulated for conifers.
