When to prune tradescantia mundula 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 tradescantia mundula
Pinch growing tips with your fingers or snip with scissors just above a leaf node to encourage branching. Cut leggy or bare stems back to within a few inches of the soil or a healthy side shoot.
Tradescantia mundula, like most spiderworts, grows quickly and tends to become leggy. Regular pinching of stem tips promotes bushier, more compact growth. Cut long, bare stems back hard to encourage fresh growth from the base. Remove dead or damaged stems at any time. This is a low-effort, high-reward plant to prune.

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.
