When to prune kohleria digitaliflora 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 kohleria digitaliflora
Cut stems down to 2–4 inches above soil after flowering declines. Deadhead spent flowers throughout the growing season. Resume normal watering post-rest to encourage new growth and reblooming.
Kohleria digitaliflora, known for its distinctive foxglove-like flowers, benefits from cutting back after each major flowering flush. Trim stems to a few inches above soil level to let the rhizomes rest and resprout vigorously. Deadhead during the season to prolong bloom. Without cutbacks, plants become leggy and flower less.

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.
