When to prune pilea 'moon valley' (friendship plant) 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 'moon valley' (friendship plant)
Pinch out the soft tip of each stem just above a leaf node using your fingers. For stem pruning, cut with clean scissors just above a healthy node — new growth will emerge from below the cut.
Pilea 'Moon Valley' benefits from regular tip-pinching to stay dense and mounding rather than stretching into long, weak stems. Pinch growing tips every few weeks during spring and summer. In spring, cut back any overly long stems to a node to reinvigorate the plant and maintain its attractive compact form.

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.
