When to prune vanda 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 vanda orchid
Cut the spent flower spike at its base with a sterilised, sharp blade. Peel away dead basal leaves gently. Only trim aerial roots if they are visibly dead or rotted — healthy aerial roots, however unruly, must be left alone.
Vanda orchids need very little pruning. Once a flower spike finishes blooming, cut it back as far as possible at the base. Remove dead or yellowing leaves from the bottom of the stem as they occur. Never cut healthy aerial roots — they are essential for water and nutrient uptake and the plant's overall health.

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.
