When to prune taxiphyllum alternans 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 taxiphyllum alternans
Use fine scissors to selectively trim overgrown or dead sections, preserving the characteristic tiered frond structure. Remove cuttings with a fine net promptly.
Taiwan moss (Taxiphyllum alternans) is a delicate aquatic moss with a naturally layered, fern-like appearance. It needs very little pruning — light trimming to maintain shape and remove dead or browning portions is all that is required. Over-pruning destroys the attractive layered texture it is valued for.

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.
