When to prune strobilanthes auriculata var. dyeriana 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 strobilanthes auriculata var. dyeriana
Pinch growing tips just above a leaf node every few weeks to promote branching. For a leggy plant, cut stems back by up to half in early spring before new growth begins, using clean pruning shears.
Persian Shield (Strobilanthes dyeriana) grows vigorously and benefits from regular pinching to stay bushy and show off its iridescent foliage. Without pruning it becomes tall and leggy. Pinch stem tips frequently in spring and summer. Cut back hard in early spring if the plant becomes overgrown.

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.
