Pest identification
What's eating my grey moor grass?
Rust (Puccinia spp.)
Signs: Orange to brown powdery pustules on leaf blades during warm, humid spells; causes early yellowing of affected tissue.
Control: Annual hard cutback in late winter removes overwintered spores; improve drainage and airflow around clumps; sulfur fungicide for rare heavy infections.
Aphids
Signs: Clusters of small insects on new spring growth; honeydew can attract sooty mould and cause minor distortion.
Control: Strong water jet; insecticidal soap for persistent colonies; allow natural predators (ladybugs, lacewings) to establish.
Slugs and Snails
Signs: Bite marks and slime trails on young leaves emerging from the crown in damp spring weather.
Control: Iron phosphate pellets in spring; reduce moisture-retaining mulch at the crown; hand-pick after dark.

Grey Moor Grass pests — FAQ
What is eating my grey moor grass?
Grey Moor Grass is extremely resilient with very low pest pressure. Rust can occasionally appear on blades in humid conditions, and aphids may visit fresh spring growth. Slugs sometimes graze young foliage at the crown. Deer and rabbits avoid it. This drought-tolerant Mediterranean grass rarely needs any pest treatment when sited in well-drained, open conditions.
