When to prune chocolate 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 chocolate orchid
Cut a spent, yellowed spike cleanly at its base with sterilized scissors. If the spike remains green, leave it or cut just above a lower node to encourage a secondary bloom.
Oncidium 'Sharry Baby' needs minimal pruning. After all flowers on a spike have faded, cut the spike back to its base only if it turns yellow or brown — healthy green spikes may rebloom from a node. Remove dead or yellowed leaves and spent pseudobulbs to keep the plant tidy.

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.
