When to prune european larch 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 european larch
Shorten new candles by half to two-thirds in spring. For branch removal, cut to a fork or a healthy bud. In late summer, shorten any over-extended shoots to maintain silhouette. Wound paste is advisable on cuts over 6 mm.
European Larch is a vigorous, back-budding deciduous conifer that handles pruning well. Pinch or cut back candles in spring once they extend to half the desired length. Structural branch removal is easiest in late autumn when bare. It responds with strong secondary growth, so follow-up summer trimming is usually needed.

Is it illegal to prune european larch 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 european larch 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.
