When to prune hand-bearing oncidium 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 hand-bearing oncidium
Cut the spent spike flush to the base using sterilised scissors. Remove dead leaf tissue by hand or with scissors. Do not disturb healthy pseudobulbs.
Hand-Bearing Oncidium is a compact miniature orchid that needs very little pruning. Snip spent flower spikes down to the base after all blooms have fallen. Remove any dead or desiccated leaf material at the base of pseudobulbs. Otherwise leave the plant alone — its small pseudobulbs should never be cut back.

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.
