UK pruning guide · RHS timing
When to prune tradescantia sillamontana 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 sillamontana
Pinch or cut growing tips just above a node. For a leggy plant, cut all stems back by one-half to two-thirds in early spring.
Tradescantia sillamontana (white velvet) grows vigorously and benefits from regular pinching to stay compact and prevent straggly stems. Pinch growing tips throughout the growing season to encourage dense, bushy growth. Cut back hard if plants become overly leggy — they regenerate quickly from old wood.

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.
