When to prune rothschild's bulbophyllum 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 rothschild's bulbophyllum
Use sterilised scissors to remove spent inflorescences at the base. When repotting every 2–3 years, cut away only fully desiccated, leafless pseudobulbs at the rhizome. Treat all cuts with cinnamon powder.
Bulbophyllum rothschildianum needs very little pruning. Cut spent inflorescences at their base once blooming is done. Do not prune healthy pseudobulbs, rhizomes, or leaves — all parts remain photosynthetically active or serve as reserves. Only remove pseudobulbs that are completely dried, shrivelled, and leafless, and only when repotting.

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.
