When to prune lime rickey heuchera in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune lime rickey heuchera
Pull away dead leaves by hand or cut with scissors at the base. Remove old flower stalks cleanly. If the crown has heaved above soil level, lift the plant, trim woody stem to healthy tissue, and replant at correct depth.
Heucheras benefit from light annual tidying rather than hard pruning. In early spring, remove any dead or tatty outer leaves and trim old flower stems from the previous year. Every 3–4 years, lift and replant heucheras to combat the woody crown heaving out of the soil — this refreshes the plant better than pruning alone.

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.
