When to prune catasetum fimbriatum 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 catasetum fimbriatum
Cut spent inflorescences at the base with sterilised scissors. Peel or trim dead, papery leaves from pseudobulbs. Only remove pseudobulbs that are completely hollow and dry.
Catasetum fimbriatum requires very little pruning. Remove spent flower spikes at the base after blooming ends. As the plant enters dry dormancy and foliage dies back, tidy away dead leaves and papery pseudobulbs. Retain plump pseudobulbs — they fuel next season's growth. No shaping is needed.

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.
