When to prune ludisia discolor 'alba' 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 ludisia discolor 'alba'
Cut spent flower spikes at the base with sterile scissors. To control legginess, pinch or cut the growing tip just above a leaf node in spring — the cut stem can be rooted as a cutting. Remove dead or yellowing leaves as they appear.
Ludisia discolor 'Alba' is a jewel orchid grown for its foliage. It rarely needs pruning beyond removing spent flower spikes and dead leaves. Cut flower spikes at the base after blooms fade. Leggy stems can be pinched back to encourage bushier growth, and stem cuttings root easily in moist medium if the plant gets too tall.

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.
