When to prune bulbophyllum longissimum 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 bulbophyllum longissimum
Snip spent flower spikes at the base with sterilised scissors. Remove yellowed or dead leaves by cutting at the pseudobulb junction. When dividing for propagation, cut the rhizome so each section retains at least two to three pseudobulbs.
Bulbophyllum longissimum is a miniature epiphytic orchid needing virtually no pruning. Once the flower spike finishes, cut it at the base — spikes do not rebloom. Remove any dead or yellowing leaves. The creeping rhizome is part of the plant's natural growth habit and should not be cut unless you are intentionally dividing the plant.

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.
