When to prune long-haired zygopetalum 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 long-haired zygopetalum
Cut spent flower spikes cleanly to the base using sterilised scissors or a blade. Peel away dead lower leaves from pseudobulbs by hand or cut flush to avoid rot harbouring pests.
Zygopetalum crinitum needs minimal pruning. Once a flower spike finishes blooming, cut it down to the base with sterile scissors. Remove any yellowed, dead, or damaged leaves at the pseudobulb base as they appear. Beyond that, no routine pruning is needed — focus on healthy pseudobulb development 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.
