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 lobb's bulbophyllum

Cut finished flower stems at the base with a sterile blade. At repotting, remove only fully dried, leafless pseudobulbs at the rhizome junction. Sterilise tools between plants and dust cuts with cinnamon.

Bulbophyllum lobbii is a low-maintenance orchid that rarely needs pruning. Remove spent flower stems at the base after blooming. Old, completely shrivelled and leafless pseudobulbs can be cut away during repotting to improve airflow. All other growth — rhizomes, healthy pseudobulbs, and leaves — should be left entirely undisturbed.

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.
