When to prune blue lace 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 blue lace zygopetalum
Use sterilised scissors to cut finished spikes to the base. Remove dead leaf sheaths from old pseudobulbs gently to improve airflow and reduce fungal risk.
Zygopetalum 'Blue Lace' requires very little pruning. Remove spent flower spikes once blooms drop by cutting to the base. Tidy away any dead or browning leaves at the pseudobulb as they occur. No further cutting is necessary — this orchid grows from pseudobulbs and does not respond to hard 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.
