Pest identification
What's eating my nicholas hakone grass?
Slugs and snails
Signs: Ragged holes and chewed margins on leaf blades; silvery slime trails visible in morning; damage is worst in cool, damp, shaded planting positions.
Control: Scatter iron phosphate pellets around clumps; hand-pick at night. Reduce moisture retention at the crown by pulling back dense mulch. Encourage ground beetles.
Aphids
Signs: Small soft insects on emerging shoots; sticky honeydew deposit and slight leaf distortion on young growth.
Control: Blast off with water; apply insecticidal soap if colonies persist. Natural enemies normally prevent build-up to damaging levels.
Spider mites (Tetranychus urticae)
Signs: Pale speckling on leaf blades; fine webbing on undersides in unusually dry or hot conditions; more likely in containers than open ground.
Control: Keep plants evenly moist and site away from reflected heat. Spray undersides with water; use neem oil or insecticidal soap if infestation develops.
