When to prune lady slipper orchid 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 lady slipper orchid
Cut the spent flower spike at its base using sterile scissors or a blade. Do not attempt to cut back to a node for reblooming — this genus produces one flower per new growth and will not rebloom from the same spike.
Lady Slipper Orchids need almost no pruning. Once a flower spike has finished blooming, cut it off at the base — unlike Phalaenopsis, Paphiopedilum spikes do not rebloom from the same stem. Leave all healthy leaves alone. Remove dead or mushy leaves only if they pull away easily or show rot.

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.
