Pest identification
What's eating my variegated purple moor grass?
Rust (Puccinia spp.)
Signs: Orange to brown powdery pustules on leaf surfaces; infected blades yellow and die back prematurely.
Control: Cut clumps back hard in late winter to remove overwintered spores; site in good air flow and avoid wetting foliage. Sulfur-based fungicide for severe cases.
Aphids
Signs: Small sap-sucking insects on new growth, leaving sticky honeydew and minor leaf distortion.
Control: Knock off with a firm water jet; encourage natural predators. Insecticidal soap spray if colonies persist.
Slugs and Snails
Signs: Ragged bite marks and slime trails on emerging spring shoots close to the soil surface.
Control: Iron phosphate pellets applied in early spring; hand-pick after dark; reduce mulch depth directly around the crown.
