Pruning western red cedar — FAQ
When should I prune western red cedar?
Late winter to early spring; a second light trim in late summer if used as a hedge. For hedges, shear the outer surface keeping a slight taper (wider at base) so lower branches receive light. For specimen trees, thin by removing entire side branches to the collar rather than shearing. Always retain green foliage on retained wood.
How often does western red cedar need pruning?
Annually for hedges; every 2–3 years for specimen shaping. Western Red Cedar (Thuja plicata) responds well to pruning and tolerates shearing better than most conifers. Prune to shape hedges or reduce size in late winter to early spring before new growth, or again lightly in late summer. Remove dead inner foliage and crossing branches. Avoid cutting back beyond green foliage — bare brown wood rarely regenerates.
