What's eating my narrow small-reed?

Narrow small-reed (Calamagrostis stricta) is a wetland native grass with very few pest problems. Aphids may colonize spring growth, and leafhoppers cause occasional leaf stippling in summer. In its preferred damp habitat, slugs can attack young emerging shoots. The plant's tough, upright blades and modest spread make it naturally resistant to most insect and animal pests.

Clusters on new shoots; sticky residue and possible sooty mold; ants may be seen attending colonies Water jet or insecticidal soap spray; beneficial insects (lacewings, ladybirds) usually provide natural control

Emerging shoots chewed in spring, most severe in the moist, low-lying habitats this species prefers Iron phosphate pellets when shoots emerge in spring; reduce soil moisture where feasible; hand-pick at dusk after rain
