When to prune cockleshell 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 cockleshell orchid
Cut the dried flower spike cleanly at its base with sterile scissors. Remove yellowed or dead leaves only. This orchid blooms sequentially up the spike, so patience before cutting is important — verify no new buds are forming at the apex.
Cockleshell orchid (Prosthechea cochleata) is a sequential bloomer that can flower for many months from a single spike. Do not cut the spike while any blooms or buds remain. Once the spike is fully spent and drying, remove it at the base. Healthy pseudobulbs and leaves need no pruning — leave them in place.

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.
