When to prune laelia purpurata 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 laelia purpurata
Sever the spent flower spike cleanly at its base using sterilised scissors. Remove dried leaf sheaths by gently peeling; avoid cutting into pseudobulbs.
Laelia purpurata, Brazil's national flower orchid, requires only minimal post-bloom tidy-up. Once the large, fragrant flowers finish in late spring to early summer, remove the spent spike at the base. Clear dead leaf sheaths from pseudobulbs. Leave all healthy pseudobulbs intact — even older backbulbs support new growth.

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.
