When to prune dendrobium 'emma white' in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune dendrobium 'emma white'
Snip spent flower spikes at their base using sterilised scissors. Leave healthy old canes intact. If a cane is completely yellow, shrivelled and papery throughout, cut it flush to the rhizome with a sterilised blade.
Dendrobium 'Emma White' is a nobile-type Dendrobium hybrid. Remove spent flower spikes after blooming ends. Retain old pseudobulbs (canes) unless fully shrivelled — they may rebloom or produce keikis. No shaping cuts to the canes are needed. Beyond spike removal, pruning is minimal.

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.
