When to prune spanish moss in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune spanish moss
Pull out dead gray-brown strands by hand or trim living strands to length with scissors. Rinse strands and shake off excess water after any cutting.
Spanish Moss (Tillandsia usneoides) needs no real pruning. It grows as long, hanging strands and can simply be thinned by removing dead or overly dry sections by hand. Trim strands to a desired length if display calls for it. Dead gray-brown sections pull away easily. No structural pruning is warranted.

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.
