What's eating my overdam variegated feather reed grass?
Rust (Puccinia spp.)
Signs: Orange to reddish-brown pustules on leaf blades and sheaths; leaves may yellow and die back during prolonged rainy, humid periods.
Control: Improve air circulation by thinning dense plantings; avoid wetting foliage. Remove affected leaves. Apply wettable sulfur or a copper-based fungicide preventively if rust recurs annually.
Aphids
Signs: Clusters of small soft insects on new shoots; sticky honeydew residue and slightly distorted or yellowed growth tips.
Control: Knock off with a strong water jet; apply insecticidal soap or neem oil if colonies persist. Natural predators such as ladybirds usually bring populations under control quickly.
