How to prune small-flowered alumroot

Early spring; deadhead after flowering. Clear away winter-damaged foliage carefully in spring without disturbing new growth. Snip spent flower stems at the base. If the woody crown heaves, carefully lift the plant, trim any dead roots, and replant at the correct depth in refreshed compost.

Annual tidy; replant lifted crowns every 2–4 years as needed. Small-flowered alumroot needs very little pruning. Remove dead or damaged leaves in early spring as fresh foliage emerges. Cut old flower stalks to the base after blooming. Like other heucheras, the crown tends to lift over time — address this by replanting or top-dressing rather than cutting into the plant.
