How Do You Prune a Bentham's Cypress?
Prune Bentham's Cypress while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.
How Do You Care for a Bentham's Cypress in Winter?
Bentham's Cypress is hardy down to USDA zone 8a, so once established it can stay outdoors through winter in that zone and warmer ones.
Water deeply in late autumn before the ground freezes — evergreens keep losing water through their needles all winter, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Bentham's Cypress can be propagated through seeds, cuttings. Similar propagation techniques also apply to arizona cypress plant care, which shares the same genus.
