Hinoki Cypress prefers consistently moist soil, especially when young. Water deeply and regularly during dry periods, allowing the top few centimeters of soil to dry out between waterings.

Avoid waterlogged conditions, which can lead to root rot. Reduce watering in winter when growth slows down.

Prune Hinoki Cypress in late winter or early spring before new growth emerges to shape the plant and remove any dead or damaged branches. Light tip pruning can be done in early summer to encourage denser growth.

Avoid heavy pruning into old wood, as it may not regrow.

Propagate Hinoki Cypress from semi-hardwood cuttings taken in late summer or early fall. Dip the cuttings in rooting hormone and plant them in a well-draining potting mix.

Keep the cuttings moist and humid in a protected environment until roots develop, which can take several months.

Repot young Hinoki Cypress every 2-3 years in early spring, just as growth starts. Move to a pot one size larger with fresh, well-draining potting mix. Mature plants may only need repotting every 4-5 years.

Ensure good drainage to prevent root rot.
