When to prune calanthe triplicata in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune calanthe triplicata
Snip spent flower stems at the base with sterilized scissors after blooming. Remove only fully dead or heavily yellowed leaves at their point of attachment. At repotting, clean old dry sheaths and discard hollow pseudobulbs.
Calanthe triplicata is an evergreen terrestrial orchid needing little pruning. Remove spent flower spikes at the base after summer blooming. Trim dead or badly yellowed leaves cleanly. Unlike deciduous calanthes, do not cut back healthy foliage during dormancy preparation. At repotting, remove exhausted pseudobulbs and dry leaf sheaths.

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.
