How to prune thalictrum rochebrunianum

Late autumn for cutback; early spring for division. Deadhead individual flower clusters if self-seeding is unwanted, cutting to a lateral stem. Once foliage yellows in autumn, cut all stems to the ground. In early spring, lift and divide large clumps with a sharp spade — replant vigorous outer sections and discard the woody centre.

Deadhead optionally; annual cutback; divide every 3–4 years. Thalictrum rochebrunianum (lavender mist meadow rue) needs minimal pruning. Deadheading is optional — spent flowers are small and not unsightly, and self-sown seedlings are useful. Cut stems back to ground level in late autumn once foliage has yellowed. Divide clumps every 3–4 years in early spring to prevent congestion and maintain flowering vigour.
