When to prune common foxglove 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 common foxglove
Cut the central flower spike back to the base of the stem once the top two-thirds of flowers have faded — this encourages smaller lateral spikes. For self-seeding, leave one or two spikes to mature fully before removing the whole plant.
Common Foxglove is a biennial that flowers in its second year, then dies. Deadheading the main spike immediately after flowering can stimulate side-shoot spikes for extended bloom. If you want self-seeding for next year's display, allow some spikes to set seed before cutting back. Tidy spent plants to the ground after seed is collected or dispersed.

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.
