Advice from our agronomist

Planting Plant in spring or early autumn at the pond margin with 0–15 cm of water over the crown; keep the rhizome near the surface in sun or partial shade.

Watering Keep the roots constantly under water; the level may vary but the planting medium must not dry out.

Pruning Remove the flower stalks and dead leaves after flowering; divide congested clumps in autumn or spring.

Feeding and winter care Needs little feeding; in spring you can give an aquatic fertiliser tablet. Very hardy; no special cover is needed.
