Darmera peltata thrives in consistently moist soil. Water deeply whenever the top layer of soil begins to dry out, especially during warmer months and dry spells.

Avoid letting the soil become waterlogged, but ensure it never dries out completely to prevent wilting.

Pruning is generally minimal, focused on removing dead or damaged foliage in late winter or early spring before new growth emerges. Spent flower stalks can be trimmed back after flowering if desired for aesthetic reasons, but are not essential.

Darmera peltata can be propagated by division of established clumps in early spring. Carefully dig up the plant and separate rhizomes with at least one bud.

Replant divisions immediately into moist soil at the desired location.

Repotting is rarely necessary as Darmera peltata prefers to be undisturbed. If division is required due to overcrowding, it's best done in early spring.

Ensure the new location provides ample space for its spread and consistent moisture.
