Pest identification
What's eating my moudry black fountain grass?
Aphids
Signs: Soft-bodied insects massing on new growth; honeydew deposits attract sooty mould and ants.
Control: Blast off with a hose jet; apply insecticidal soap if colonies persist. Encourage natural predators by avoiding broad-spectrum pesticides.
Rust (Puccinia spp.)
Signs: Orange to reddish-brown spore pustules on leaf surfaces; premature leaf die-back in persistently humid or wet conditions.
Control: Ensure good air circulation; water at root level. Remove infected foliage. Apply sulfur-based fungicide preventively in rust-prone gardens.
Spider mites (Tetranychus urticae)
Signs: Fine pale stippling across blade surface; webbing on leaf undersides during hot dry spells.
Control: Water foliage undersides to raise humidity; treat with neem oil or insecticidal soap spray. Repeat weekly until resolved.
