When to prune gireoud's brassia 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 gireoud's brassia
Use sterilised scissors for all cuts. Trim spent spikes cleanly to the base. Remove dried leaf sheaths by peeling or cutting flush to the pseudobulb; avoid leaving stubs that can harbour rot or pests.
Brassia gireoudiana is a minimal-pruning orchid. Cut spent flower spikes to the base after blooming ends. Tidy dead or yellowed leaf material from older pseudobulbs as it appears. Healthy green pseudobulbs and leaves should be left intact — they supply energy for the next growth and flowering cycle.

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.
