What's eating my lapidaria margaretae?
Mealybugs
Signs: Cottony white clusters between the fleshy leaf segments; honeydew and sooty mould on leaf surfaces
Control: Spot-treat with an isopropyl-alcohol swab; spray the rosette base with diluted neem oil or insecticidal soap, avoiding water pooling on leaves
Root mealybugs
Signs: Plant looks dehydrated and fails to plump up after watering; white waxy colonies on roots
Control: Remove plant from pot, shake off old mix, treat roots with an imidacloprid soak or diluted alcohol, and repot in fresh mineral substrate
Spider mites
Signs: Silvery or bronze stippling on leaf surfaces; fine webbing in very dry indoor air
Control: Wipe leaf surfaces with a damp cloth; apply insecticidal soap or neem oil; ensure adequate ventilation around the plant
