When to prune tolumnia variegata 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 tolumnia variegata
Snip the finished spike cleanly at its base with sterilised scissors. Peel away any dried or dead leaf sheaths at the base of fans. Do not cut into live green tissue.
Tolumnia variegata (formerly equitant oncidium) needs very little pruning. Remove spent flower spikes at the base after blooming ends. Trim dead or brown leaf tips with sterile scissors. Healthy fans of leaves should never be cut back — the plant is small and removing live tissue sets it back significantly.

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.
