How to prune spring symphony tiarella
Snip spent flower stems at the base once blooms finish. In early spring, cut or pull dead and damaged foliage away from the crown, leaving healthy leaves intact.
Spring Symphony Tiarella needs minimal pruning. Deadhead spent flower spikes at the base after the late-spring display to tidy the plant and encourage fresh foliage. In early spring, remove any winter-damaged or tatty leaves from the crown. It is semi-evergreen, so avoid a hard autumn cutback — light spring tidying is all that's needed.

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.
