When to prune coelogyne flaccida 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 coelogyne flaccida
Cut spent spikes at their base with sterile scissors or a clean blade. If any pseudobulbs become completely hollow and papery, carefully detach and discard them. Leave all firm pseudobulbs — even old ones — in place.
Coelogyne flaccida is a low-pruning orchid. Remove spent pendant flower spikes at their base once blooming ends. Healthy pseudobulbs must not be cut — they feed next season's flowering. No further pruning is required. Focus care energy on appropriate cool temperatures and seasonal dry rest instead.

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.
