When to prune hooded dendrobium 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 hooded dendrobium
Cut completely desiccated canes cleanly at the base with sterile scissors. Never remove canes that still show any green or that bore flowers recently.
Hooded Dendrobium is a deciduous orchid that sheds its leaves seasonally — this is normal, not a pruning cue. Remove only fully dead canes once leaves have dropped and canes are completely brown and dry. Leave green and flowering canes untouched; flowers emerge from leafless old canes and pruning them eliminates blooms.

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.
