When to prune geranium cantabrigiense 'biokovo' 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 geranium cantabrigiense 'biokovo'
Shear spent flowerheads and the top third of foliage after bloom to promote new ground-hugging growth. In spring, selectively remove any dead or frost-browned stems with scissors.
Geranium cantabrigiense 'Biokovo' forms a compact, semi-evergreen mat and needs very little pruning. Shear lightly after the early-summer white-pink flowers fade to keep the ground cover dense. Remove winter-damaged stems in early spring. Avoid cutting into the woody base — this cultivar resents hard pruning.

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.
