When to prune pilea pumila 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 pilea pumila
Pinch or snip stray or dead stems back to a healthy leaf node. No structural pruning required.
Pilea pumila (Clearweed) is typically grown as an annual or short-lived houseplant and requires virtually no pruning. Remove dead or yellowing leaves as they appear. If grown as a trailing accent, you can trim stray stems to tidy the plant. No shaping or heavy pruning is necessary.

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.
