When to prune sukhakul's 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 sukhakul's slipper orchid
Sterilise scissors before use. Cut the spent spike at the base of the plant, close to the foliage. Remove dead leaves at the rhizome level; never cut into healthy green tissue unnecessarily.
Sukhakul's Slipper Orchid requires minimal pruning. Remove the spent flower spike at the base once blooming finishes — unlike some orchids, Paphiopedilum spikes do not rebloom. Trim dead or yellowing leaves cleanly at the base. Each new growth produces one spike, so protect all healthy foliage.

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.
