When to prune denison's vanda 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 denison's vanda
Snip the spent spike cleanly at its base. Trim dead or damaged leaves flush with the stem using sterile scissors. Avoid cutting living aerial roots — they are essential for water and nutrient uptake.
Denison's Vanda requires very little pruning. As a monopodial orchid it grows on a single stem and does not branch out or need shaping. Simply remove spent flower spikes at the base once blooms fade, and trim away any dead or yellowing leaves with a sterile blade. Never cut green aerial roots.

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.
