Pest identification
What's eating my central australian cabbage palm?
Scale insects
Signs: Hard or soft waxy bumps on petioles and leaf undersides; progressive yellowing and a shiny, sticky residue from honeydew.
Control: Apply horticultural oil or insecticidal soap spray in cooler morning hours. Systemic imidacloprid drench for large landscape specimens.
Palm aphids
Signs: Colonies on new fronds; sooty mould develops on honeydew, reducing photosynthesis and the palm's appearance.
Control: Water jet to knock off colonies; neem oil spray. Encourage natural predators — lacewings and parasitic wasps are effective in warm-climate gardens.
Spider mites
Signs: Stippled, dusty leaflets with faint webbing; worst during extended dry or hot spells.
Control: Deep-water the root zone to reduce plant stress. Spray leaflet undersides with insecticidal soap or neem oil in the cool of the morning.
