When to prune pelargonium 'mrs pollock' 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 'mrs pollock'
Remove spent flower heads at their base to redirect energy to foliage. Pinch stem tips above a node in spring. Cut reverted plain-green shoots back to their origin. Reduce all stems by one-third in late summer with clean secateurs.
Pelargonium 'Mrs Pollock' is a highly ornamental tricolour zonal pelargonium grown mainly for its spectacular red, gold, and green foliage. Deadhead to prevent energy going to seed. Pinch tips in spring for a bushy shape. Remove any plain-green reverted shoots immediately to preserve the distinctive tricolour patterning. Cut back by one-third in late summer.

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.
