When to prune dendrobium loddigesii 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 dendrobium loddigesii
Use sterilised fine scissors to remove spent flower spikes at their base. Only cut old, completely desiccated canes at the rhizome. Do not remove canes that still have any green tissue or plumpness, even if leafless.
Dendrobium loddigesii is a compact, deciduous miniature orchid that drops its leaves in winter before flowering. Remove spent flower spikes after blooming. Old leafless canes that have fully shrivelled can be cut away. Otherwise, leave all canes — even leafless ones — as they contribute energy reserves.

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.
