When to prune andorra compact juniper 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 andorra compact juniper
Trim stray or damaged stems back to a healthy side shoot within the green foliage zone. Do not shear flat — this exposes dead brown interior wood that will not regrow. Work selectively with bypass pruners.
Andorra Compact Juniper is a dense, spreading shrub that largely maintains its own form without intervention. Prune only to remove dead or damaged wood and to control any outward-wandering stems. Avoid cutting into bare brown interior wood — junipers do not regenerate from old leafless growth.

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.
