When to prune pelargonium 'paul crampel' 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 pelargonium 'paul crampel'
Remove spent flower heads at their base. Pinch growing tips above a leaf node in spring. In late summer, shorten all main stems by one-third to one-half with clean, sharp secateurs, cutting just above a node to encourage healthy regrowth.
Pelargonium 'Paul Crampel' is a classic single-flowered zonal pelargonium with vivid scarlet blooms, long grown as a bedding and container staple. Deadhead spent flower clusters regularly to sustain prolific blooming. Pinch stem tips in spring for a bushy, well-branched plant. Cut back by one-third to one-half in late summer before overwintering.

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.
