What maintenance?

Regularly renew the mulch at the base and water regularly in dry weather. The soil should not dry out.

In regions with a harsh climate, protect young plants of the Japanese anemone , as winter approaches, under a carpet of dead leaves. Elsewhere and later, the gesture is useless, the plant being hardy down to -15/-20°C.
