When to prune corsage 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 corsage orchid
Cut spent spikes at their base near the sheath with sterile scissors. Remove fully dead back-bulbs only. Divide congested clumps during repotting rather than pruning individual canes.
Cattleya labiata needs minimal pruning. After flowers fade, cut the spent flower spike down to the base of the sheath with sterile scissors. Leave all pseudobulbs and rhizome intact. Remove only yellowed or dead back-bulbs that are completely shrivelled. Dividing during repotting every 2–3 years keeps the plant vigorous without traditional 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.
