UK pruning guide · RHS timing
When to prune camellia 'donation' 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 camellia 'donation'
Trim lightly to maintain shape, cutting back to just above a healthy outward-facing bud. Remove dead, crossing, or congested branches. As a compact hybrid it rarely needs more than light tidying — remove no more than one-third of live growth in any one year.
Camellia 'Donation' (C. × williamsii) is naturally compact and self-cleaning — it drops spent flowers without deadheading. It needs less pruning than japonica. Shape lightly immediately after the last flowers fall (typically April–May). Bud set begins earlier than japonica, so all cuts must be done by late June.

Is it illegal to prune camellia 'donation' 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 camellia 'donation' 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.
