When to prune large-flowered maxillaria 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 large-flowered maxillaria
Cut spent flower stems at their base with sterile scissors. Remove dead leaf tissue cleanly. If a pseudobulb shows signs of rot or disease, cut it away and dust the cut surface with powdered cinnamon or a fungicide.
Large-Flowered Maxillaria requires minimal pruning. After flowers fade, remove the spent flower stem at the base. Trim dead or yellowing leaves with a sterile blade, and cut away any visibly diseased pseudobulb tissue. Healthy pseudobulbs — including older ones without leaves — store carbohydrates and should not be removed unless they are shrivelled or rotting.

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.
