When to prune cattleya 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 cattleya orchid
Use a sterilised blade or scissors. Cut the spent flower spike flush with its base. Trim yellowed leaves close to the pseudobulb. When repotting, detach leafless back-bulbs cleanly, dust cuts with cinnamon or powdered sulphur to prevent rot.
Cattleya orchids need minimal pruning. After a flower spike finishes, cut it back to the base of the pseudobulb with a sterile blade. Remove dead, shrivelled, or yellowed leaves and any dead pseudobulbs (back-bulbs) when repotting. Do not cut healthy green pseudobulbs — they store energy for future blooms.

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.
