When to prune pelargonium 'dolly varden' 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 'dolly varden'
Pinch out shoot tips regularly during the growing season to promote branching. Cut back stems to one-third their length using clean, sharp scissors, cutting just above a leaf node. Always remove any all-green reversions at their point of origin.
Pelargonium 'Dolly Varden' benefits from regular pruning to keep its variegated foliage bushy and encourage flowering. Deadhead spent blooms continuously. Cut back by one-third in late summer or early spring to prevent legginess. Remove any plain green shoots promptly — they grow faster and will crowd out the variegated growth.

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.
