When to prune crystal anthurium 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 crystal anthurium
Cut petioles cleanly at the base with sterile scissors. For spent spathes, cut the entire flower stem at the base once the spadix and spathe have fully faded.
Crystal Anthurium requires only light, occasional pruning. Remove spent flower spathes once they fade and yellow, and cut away any damaged or yellowing leaves at the base of their petioles. The plant does not branch from cut stems. Removing old foliage keeps the plant tidy and focuses energy on its striking new velvet leaves.

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.
