When to prune bosnian pine 'compact gem' 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 bosnian pine 'compact gem'
Remove any dead or discoloured branches with clean, sharp pruners at the point of origin. If a single shoot is growing noticeably out of character, trim it back to a healthy side bud in early spring.
Bosnian Pine 'Compact Gem' is a naturally dwarf, dense cultivar selected specifically for its tight, globe-like form. It needs almost no pruning. Its slow, compact growth requires no shaping. Remove dead or damaged shoots only. Do not attempt to further reduce its size — that defeats the purpose of the cultivar.

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.
