When to prune pelargonium 'fragrans' 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 'fragrans'
Pinch out stem tips just above a leaf node to encourage a dense, mounding habit. Trim lightly after the main flush of small white flowers. Avoid removing more than one-third of growth at once.
Pelargonium 'Fragrans' (nutmeg/pine-scented geranium) is a small, bushy herb that benefits from light annual pruning to prevent it becoming woody and sprawling. Pinch stem tips in spring, trim lightly after flowering, and remove dead growth as it appears. It stays naturally compact compared to taller scented-leaf types.

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.
