When to prune stardust 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 stardust dendrobium
Cut the spent flower stalk to within 1 inch of its origin point on the cane using sterile shears. Remove only fully dead, shrivelled canes — healthy-looking canes should not be cut.
Dendrobium 'Stardust' is a hybrid Dendrobium that needs minimal pruning. After flowers fade and the flower stalk turns yellow or brown, cut it back to within about an inch of where it emerged from the cane. Remove dead or yellowing canes at the base, but leave healthy canes intact — they store energy and may re-bloom.

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.
