When to prune tradescantia blossfeldiana in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune tradescantia blossfeldiana
Pinch stem tips just above a node with fingers or scissors. After flowering, cut flowering stems back to the nearest healthy leaf. For a hard reset, cut the whole plant back by half in spring; it recovers quickly.
Tradescantia blossfeldiana (inch plant / Cerinthoides group) becomes leggy without regular pinching. Pinch stem tips frequently to promote branching and keep growth compact. After flowering, trim back stems to encourage a fresh flush. This plant tolerates cutting back well and cuttings root very easily.

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.
