When to prune sublime 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 sublime slipper orchid
Use sterile scissors or a blade to cut the spent flower spike at its base, as close to the foliage as possible. Wipe blades with isopropyl alcohol between cuts to prevent disease spread.
Paphiopedilum insigne needs minimal pruning. Once a flower spike finishes blooming, cut it off at the base near the leaves. Remove any yellowed or dead leaves cleanly at the base. Do not cut into healthy green foliage. Beyond spent spike removal, this orchid requires no routine pruning.

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.
