What's eating my abiqua drinking gourd hosta?

Abiqua Drinking Gourd Hosta has deeply cupped, heavily corrugated blue-green leaves. The thick cupping actually collects water and debris, which slugs exploit as cover. Deer, rabbits, and vine weevil are also threats. The deep cup shape can trap slug pellets effectively — iron phosphate bait placed in the cups provides good protection.

Holes in the cupped leaf surface and along margins; slime trails visible inside the cups after rain Place iron phosphate pellets in and around the cupped leaves; hand-pick from inside the cups at night; encourage natural predators like ground beetles and hedgehogs

Foliage browsed heavily; the thick leaves are targeted in lean seasons when other food is scarce Surround beds with tall deer fencing or apply repellent sprays; motion-activated deterrents help in areas with persistent deer browsing

Notched leaf margins; root grubs sever the crown below soil, causing plant collapse Treat soil with nematodes in late summer and early autumn; examine soil around the crown when dividing the plant
