Netted Chain Fern pests — FAQ
What is eating my netted chain fern?
Netted chain fern (Lorinseria areolata) grows in wet woodland gardens and is most threatened by slugs and snails on its fronds. Deer will browse it in open woodland. Vine weevil larvae can damage crowns in drained beds. It is generally robust and relatively pest-free once established in its preferred boggy habitat.
