About Western Arborvitae

Rated Occasionally Damaged rather than Frequently, which makes it a better hedging bet than American arborvitae where deer are present, though young plants still need protection. Much larger in time and it wants the cool moist conditions of its Pacific Northwest home; it struggles in hot dry summers.
