Pest identification
What's eating my sacchariflorus silver grass?
Aphids
Signs: Soft insect colonies on emerging shoots; honeydew deposits on leaves attract sooty mould; reduced shoot vigour
Control: Direct a firm water jet at affected shoots; apply insecticidal soap or neem oil; natural predators typically take over by midsummer
Mealybug (stem-sheath species)
Signs: White waxy deposits inside stem sheaths; yellowing and weakening of individual canes; sooty mould on honeydew
Control: Cut all stems to ground level in late winter; treat regrowth with horticultural oil to smother overwintering eggs
Deer and rabbits
Signs: Young spring shoots grazed; established colonies recover readily but can be repeatedly browsed in deer-pressure areas
Control: Apply deer repellent spray to emerging shoots; physical fencing is most reliable in high-pressure areas
