When to prune cymbidium 'showgirl' 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 cymbidium 'showgirl'
Cut finished spikes to the base with sterilised scissors. At repotting every 3–4 years, divide clumps into sections of 3–4 pseudobulbs and discard shrivelled leafless back-bulbs.
Cymbidium 'Showgirl' is a standard cymbidium hybrid: remove spent flower spikes at the base as soon as the blooms finish to conserve plant energy. Trim brown leaf tips cosmetically if you wish. Old leafless back-bulbs can be removed at repotting. Never cut healthy green leaves or plump pseudobulbs.

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.
