How to prune thalictrum 'elin'

Cut back in late autumn or early spring; deadhead optionally after flowering. After frost has blackened the stems, cut all growth to near ground level. No in-season pruning is needed. Stake early in the season if the plant is in an exposed position, rather than pruning it short.

It requires minimal pruning — cut it back to ground level in late autumn or early spring to clear old stems. Deadhead if self-seeding is a concern. Staking in exposed sites is more important than pruning.
