When to prune reed-stem orchid 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 reed-stem orchid
Cut the spent flower cluster from the top of the cane with sterilised scissors. Leave the cane in place — it will produce keikis at nodes. Once a keiki has developed roots 5–8 cm long, detach it and pot into orchid bark.
Reed-stem Epidendrums need careful pruning: cut spent flower heads back, but do not remove old canes entirely. Old canes and flower spikes produce keikis (baby plants) that can be detached and potted once they develop their own roots. Only remove a cane if it is completely dead, since live canes actively produce 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.
