Santa Cruz cypress prefers well-drained soil and is drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter.

Overwatering can lead to root rot, so ensure good drainage is a priority.

Pruning is generally minimal for Santa Cruz cypress, primarily for shaping or removing dead, damaged, or crossing branches. Make cuts just outside the branch collar.

The best time for any significant pruning is in late winter or early spring before new growth begins.

Propagation is typically done from seeds, which may require stratification (a period of cold, moist conditions) to break dormancy. Cuttings can also be taken from semi-hardwood in late summer or early fall, but rooting success can be variable and requires careful attention to humidity.

Repotting is rarely necessary for established Santa Cruz cypress. If planting a young tree or specimen that has become pot-bound, choose a pot only slightly larger than the current one.

Use a well-draining potting mix and repot in early spring before active growth begins.
