What's eating my beautiful graptopetalum?

Beautiful Graptopetalum is a hardy succulent with few serious pests. Mealybugs are the most likely indoor problem, hiding in tight rosette centres. Aphids can appear on spring growth, and vine weevil larvae may attack roots of pot-grown specimens. The powdery farina on leaves can mask early mealybug colonies, so inspect rosette centres carefully.

White waxy deposits in rosette centre and leaf axils; leaves pucker and plant declines Remove with alcohol-dipped cotton swab; spray with neem oil; avoid wetting the farina-coated leaves directly if possible; repeat weekly

Soft insect clusters on new growth in spring; sticky honeydew and leaf distortion Knock off with targeted water spray; apply insecticidal soap; monitor new growth weekly through spring

Sudden wilting as white grubs consume roots; adult notching on leaf margins at night Unpot and remove grubs by hand; apply nematode drench (Steinernema kraussei) to moist compost in late summer or autumn
