When to prune rothschild'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 rothschild's slipper orchid
Cut the finished flower spike at its base with sterile scissors. Remove only completely brown or rotted leaves, cutting flush with the base. Never remove green leaves — each growth carries only one fan.
Paphiopedilum rothschildianum is a slow-growing species that requires almost no pruning. Remove spent flower spikes at the base once all blooms have dropped. Trim any dead or rotting leaves cleanly at their base. Healthy leaves should never be cut — this orchid grows from a single fan of leaves per growth.

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.
