When to prune red polka dot 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 red polka dot plant
Pinch growing tips back to just above a leaf node with your fingers or clean scissors. Cut spent or flowered stems back hard to a low node to encourage fresh basal growth.
Like all Hypoestes, 'Red Splash' grows fast and gets leggy without regular tip-pinching. Pinch back to a leaf node every few weeks to keep the plant compact and colorful. Nip out flower spikes promptly — once a stem flowers it declines, and the bold red spotting fades on bolting growth.

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.
