When to prune dendrochilum cobbianum 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 cobbianum
Using sterilized scissors or a blade, cut the spent flower spike at its base. Peel or snip away only visibly dead or fully yellowed leaves. Do not remove green pseudobulbs or healthy leaves.
Dendrochilum cobbianum is a compact chain orchid that requires almost no pruning. Simply remove spent flower spikes after blooming and cut away any dead or yellowing leaves at their base. Never trim healthy pseudobulbs or living foliage — this plant's energy reserves depend on keeping pseudobulbs intact.

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.
