When to prune running tapestry tiarella in the UK
Why the timing differs here
This one bleeds sap heavily if cut in late winter or early spring, so the RHS advises pruning in late summer or early autumn instead — the opposite of the general dormant-season rule most pruning guides give.
How to prune running tapestry tiarella
Snip spent flower stems to the base. In early spring, shear the mat to a few centimetres above the ground to refresh foliage. Trim stolons at the planting boundary to control spread.
Running Tapestry Tiarella (T. cordifolia) spreads by stolons and needs minimal pruning. Cut back spent flower spikes at the base after blooming to keep things tidy. In early spring, shear over the mat lightly to remove any winter-damaged foliage and encourage fresh growth. Control spread by pulling or cutting back stolons at the edges.

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.
