When to prune callicarpa 'pearl glam' 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 callicarpa 'pearl glam'
Cut all stems back hard to 12–18 in (30–45 cm) above ground using loppers or sharp secateurs. Remove any dead or damaged wood entirely to the base. This hard renewal prune produces the longest, most berry-laden new shoots.
Callicarpa 'Pearl Glam' (beautyberry) produces its showy white berries on current-season growth, so a hard annual cut in late winter maximises fruiting wood and berry display. Cut all stems back to 12–18 inches (30–45 cm) or close to the base. New growth emerges vigorously and carries the season's berry crop.

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.
