When to prune hypoestes phyllostachya 'splash select white' 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 hypoestes phyllostachya 'splash select white'
Pinch or snip stem tips just above a leaf node to encourage bushy branching. Remove any emerging flower spikes immediately with clean scissors to extend the plant's decorative lifespan.
Polka dot plants need regular pinching to stay compact and colorful. Without pruning they bolt, go leggy, and lose their vivid leaf variegation. Pinch stem tips back by half every few weeks and cut flower spikes off as soon as they appear — flowering signals the end of the plant's ornamental life.

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.
