When to prune emerald spike 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 emerald spike moss
Pinch or snip stem tips to encourage branching. Cut dead sections back to living green tissue at the base.
Emerald spike moss needs minimal pruning. Trim back any leggy or overly long stems to keep the plant compact and bushy, and remove dead or brown sections at the base. It responds well to light pinching. Avoid cutting into woody or bare stems — they rarely re-sprout reliably.

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.
