When to prune pelargonium odoratissimum 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 odoratissimum
Pinch or snip stem tips above a leaf node to promote a denser, mounding habit. Cut flowering stems back to healthy foliage after blooms fade. Avoid cutting into completely bare woody stems as they may not re-shoot reliably.
Apple-scented Pelargonium odoratissimum is a low, spreading herb that grows quickly and needs regular trimming to prevent it sprawling untidily. Pinch stem tips in spring and trim back after flowering. Remove spent flower stalks promptly. It recovers well from moderate pruning throughout the growing season.

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.
