When to prune splash 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 splash polka dot plant
Pinch or snip the growing tip of each stem back to just above a pair of leaves every few weeks. Remove any emerging flower spikes immediately at the base to prolong foliage quality.
Hypoestes phyllostachya 'Splash' becomes leggy quickly and needs regular pinching to stay bushy. Pinch or snip stem tips just above a leaf node to encourage branching. Remove flower spikes as soon as they appear — flowering signals the end of the plant's life cycle and foliage color fades fast once it bolts.

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.
