What's eating my silver spike grass?
Aphids
Signs: Clusters of small insects on young shoots, sticky honeydew residue, possible yellowing of new growth
Control: Knock off with a water jet; apply insecticidal soap; natural predator populations (lacewings, ladybirds) usually provide adequate control
Rust mites (Eriophyidae)
Signs: Fine silvery or bronze stippling across leaf surfaces, blades may look bleached or dull in severe cases
Control: Ensure good airflow around clumps; remove and dispose of heavily affected leaves; apply horticultural oil (neem) in persistent cases

What is eating my silver spike grass?
Silver spike grass (Stipa calamagrostis) is a tough, drought-tolerant grass that pests largely ignore. Aphids occasionally colonize soft new growth, and rust mites can cause silvery flecking on leaves during hot, dry summers. Animals rarely bother it. Good air circulation and avoiding overwatering keeps this species almost trouble-free.
