When to prune pelargonium peltatum 'barrocas' 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 'barrocas'
Remove spent flower clusters at the base of the peduncle. Cut leggy stems back to a healthy leaf node using clean secateurs. In overwintered plants, cut harder in early spring to about half the previous year's growth.
Pelargonium peltatum 'Barrocas' is a trailing ivy-leaf geranium that flowers best with regular deadheading and periodic trimming. Remove spent flower heads continuously. Cut trailing stems back by up to one-third in late summer to prevent legginess and stimulate another flush of bloom before season's end.

Pruning itself is not illegal, but destroying an active nest is.

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.
