When to prune geranium himalayense 'gravetye' 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 himalayense 'gravetye'
Use shears or scissors to cut the entire clump back to 3–4 inches above soil level. Clear the cut foliage and water well; fresh growth and a secondary bloom usually follow within 4–6 weeks.
Geranium himalayense 'Gravetye' benefits from a hard cut-back after its main early-summer flush. Shear the whole clump to a few inches above ground; this removes tatty foliage, tidies the plant, and often triggers a second wave of flowers later in summer. Without cutting back it simply looks messy.

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.
