When to prune geranium cantabrigiense 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
Use garden shears or scissors to trim the spent flower stems and any straggly growth by one-third after bloom. In spring, pull out or snip any brown winter-killed stems at ground level.
Geranium cantabrigiense is a low, spreading ground-cover cranesbill needing minimal pruning. Lightly trim or shear after flowering in early summer to neaten the mat and encourage fresh foliage. Remove any dead or winter-damaged stems in early spring. No hard pruning needed; over-cutting the low mats can stall recovery.

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.
