When to prune spathoglottis kimballiana 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 spathoglottis kimballiana
Snip spent flower spikes at their base with clean, sterilized scissors once flowers have fully dropped. Cut away yellowed or dead leaves at the pseudobulb base. Leave all firm, green growth undisturbed.
Spathoglottis kimballiana, like others in the genus, needs modest pruning. Remove spent flower spikes promptly at the base after blooming — this can encourage reblooming. Trim dead or yellowing leaves at their base. Do not cut into healthy pseudobulbs or green foliage. The plant may bloom more than once annually in good conditions.

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.
