How to prune sanguisorba canadensis

Deadhead late summer; cut back in late autumn or early spring. Remove spent flower spikes by cutting to a lateral shoot or back to the basal foliage. In autumn after foliage dies back, cut stems down to ground level. Divide congested clumps in early spring — lift, split with two forks back-to-back, and replant healthy sections.

Deadhead as needed; annual cutback; divide every 3–4 years. Sanguisorba canadensis (Canadian burnet) needs very little pruning. Deadhead spent white bottlebrush flowers to keep the plant tidy — or leave them for seedheads that attract birds. Cut the whole plant back to its basal rosette in late autumn or early spring. Divide large clumps every 3–4 years in spring to maintain vigour.
