When to prune hinoki cypress 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 hinoki cypress
Use hand pruners to remove dead or crossing branches back to a live lateral. Do not shear or cut into the fan-like branch tips — this ruins the natural layered appearance and exposes bare stems that will not re-bud.
Hinoki Cypress 'Nana Gracilis' is a slow-growing, fan-branched dwarf that is highly architectural and virtually self-maintaining. It rarely benefits from pruning and shearing destroys its tiered, layered character. Remove only dead, damaged, or crossing branches. Any hard cuts into bare wood will not regenerate.

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.
