When to prune dendrochilum filiforme 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 dendrochilum filiforme
Snip spent flower spikes cleanly at the base using sterilized scissors. Carefully remove any dead or fully browned leaves. The thread-like foliage is delicate — handle minimally to avoid bruising healthy tissue.
Dendrochilum filiforme, a thread-leafed chain orchid, rarely needs pruning. Its fine, grass-like foliage should be left alone. Once flowering is complete, remove spent flower spikes at their base. Clear away dead or browned foliage as it appears. Avoid cutting into live pseudobulbs or healthy growth.

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.
