When to prune leatherleaf viburnum in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune leatherleaf viburnum
For size control, shorten the longest stems by up to one-third after flowering, cutting to a strong lateral bud. To rejuvenate an overgrown plant, stagger hard cuts over two to three seasons. As a hedge, trim once after bloom.
Leatherleaf viburnum is a large, fast-growing evergreen shrub that tolerates hard pruning but rarely needs it. Prune lightly after flowering to control size. Because it blooms on the previous year's wood, autumn or winter pruning removes flower buds. It makes an excellent informal hedge with minimal intervention.

Is it illegal to prune leatherleaf viburnum 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. Check leatherleaf viburnum for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
