When to prune japanese cedar 'elegans' in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune japanese cedar 'elegans'
Shear or hand-prune the outer tips lightly — remove no more than one-third of the current year's growth. Work evenly around the plant to preserve its natural form. Do not cut back to bare, needle-free wood as regrowth is unreliable.
Cryptomeria japonica 'Elegans' is a feathery, soft-needled cultivar that tolerates light shearing well. Trim lightly in late spring after the new growth flush to maintain a tidy outline or encourage density. Avoid cutting into old bare wood, which does not regenerate. Hard renovation pruning is not appropriate for this cultivar.

Is it illegal to prune japanese cedar 'elegans' in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
