When to prune cockleshell butterfly 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 butterfly orchid
Cut the spent spike cleanly at the base of the pseudobulb using sterilised scissors or pruning shears. Remove dead basal leaves by peeling gently downward. Avoid cutting into pseudobulbs, which store energy for the next bloom.
Encyclia orchids need minimal pruning. Once flowering is fully finished and the spike browns, cut it to the base with sterilised scissors — the spike grows from the pseudobulb top and will not rebloom. Remove dead or yellowing basal leaves as they appear. Healthy pseudobulbs should never be cut.

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.
