When to prune zygopetalum 'blue eyes' 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 zygopetalum 'blue eyes'
Snip spent flower spikes to the base with sterilised scissors. Cut dead leaves cleanly at the base. Leave all healthy and semi-firm pseudobulbs intact on the plant.
Zygopetalum 'Blue Eyes' is a sympodial orchid that needs minimal pruning. Once the flower spike has finished, cut it to the base. Remove yellowed or dead leaves and any completely shrivelled pseudobulbs. Firm older pseudobulbs store nutrients and should be kept. No other pruning routine is required.

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.
