When to prune pelargonium graveolens 'grey lady plymouth' 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 graveolens 'grey lady plymouth'
Pinch or snip stem tips above a leaf node throughout the growing season to prevent legginess. In spring, cut all main stems back by up to half, just above a strong leaf node; remove any all-green reversion shoots promptly to preserve the variegation.
Pelargonium graveolens 'Grey Lady Plymouth' is a variegated rose-scented pelargonium valued for its silver-edged, fragrant leaves. Pinch growing tips regularly to maintain a bushy, well-branched habit and cut back by one-third to one-half in early spring to encourage vigorous, aromatic new foliage and prevent the plant becoming woody.

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.
