When to prune pelargonium echinatum 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 echinatum
Remove any completely dead or shrivelled stems at their base using clean scissors. Do not cut back healthy green or semi-dormant stems — they will resume growth naturally. Handle with care; the stipular spines are sharp.
Pelargonium echinatum is a spiny-stemmed succulent species that goes fully dormant in summer. It needs very little pruning — remove dead stems cleanly at their base after dormancy ends in autumn. Avoid heavy cutting as the plant's cactus-like architecture is part of its appeal and it resents unnecessary wounding.

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.
