When to prune wild crabapple bonsai 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 wild crabapple bonsai
After leaf drop, cut back to reveal the branch structure, leaving identified flower buds intact. During the growing season, pinch new shoots back to 1–2 leaves. Thin fruit clusters to one per cluster to prevent the tree weakening.
Wild Crabapple bonsai needs regular pruning to maintain miniature form, encourage flowering, and build fine ramification. Prune in late autumn after leaf drop so you can distinguish flower buds from leaf buds and avoid removing all bloom potential. Shorten new shoots during the growing season to 1–2 leaves to keep the silhouette tight.

Pruning itself is not illegal, but destroying an active nest is.

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.
