When to prune pelargonium peltatum 'tomcat' in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune pelargonium peltatum 'tomcat'
Deadhead by snapping or cutting spent flower stems at the base. Trim trailing stems back by one-third with clean secateurs, cutting just above a leaf node to encourage branching and new flower buds.
Pelargonium peltatum 'Tomcat' is a trailing ivy-leaf geranium that benefits from regular pruning to stay bushy and free-flowering. Deadhead spent blooms continuously. Cut back long, leggy stems by one-third in late summer or autumn. In frost-free climates, a harder cut in early spring rejuvenates the plant.

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.
