How to prune rodgersia pinnata

Deadhead after flowering in summer; cut back to ground in late autumn or early spring. Snip spent flower stems at their base. In autumn or early spring, cut all old foliage and stems to ground level. Avoid disturbing the rhizomes when cutting back.

Deadhead optionally; annual cutback once per year. Rodgersia pinnata needs very little pruning. Remove faded flower plumes at the stem base after blooming if tidiness is desired. The bold, pinnate foliage is fully herbaceous and dies back naturally in winter — cut old stems to ground level in late autumn or early spring before new growth emerges.
