When to prune pelargonium peltatum 'sofie cascade' 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 peltatum 'sofie cascade'
Remove spent flower heads at their base. Pinch growing tips just above a leaf node early in the season. At season's end, shorten all trailing stems by one-third to one-half with clean secateurs to keep the plant compact.
Pelargonium peltatum 'Sofie Cascade' is a trailing ivy-leaved pelargonium selected for vigorous cascading growth and prolific flowering. Deadhead spent blooms to sustain flowering through the season. Pinch stem tips in early spring to encourage branching at the base. 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.
