UK pruning guide · RHS timing
When to prune nun's 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 nun's orchid
Sever the spent flower spike at its base with clean, sterile scissors. Trim any dead or badly damaged leaves to the base. Avoid cutting healthy green pseudobulbs — older ones can still support future growth.
Nun's orchid needs minimal pruning. Once the flower spike finishes blooming and begins to yellow and wither, cut it off at the base. Keep healthy pseudobulbs and foliage intact — they fuel next season's growth. Remove only dead or damaged leaves. This terrestrial orchid is a straightforward plant that rewards restraint.

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.
