What's eating my graptopetalum macdougallii?

Graptopetalum macdougallii, like most succulent houseplants, is most threatened by mealybugs and root mealybugs. Spider mites and fungus gnats also appear when conditions are dry or soil stays wet too long. Inspect the rosette crevices regularly and avoid overwatering to keep pests at bay.

White cottony clusters in leaf axils and rosette centres; leaves yellow and shrivel Dab with 70% isopropyl alcohol on a cotton swab; spray with diluted neem oil; isolate the plant

Stunted growth and wilting despite adequate watering; white waxy coating visible on roots Unpot, rinse roots, drench with imidacloprid or insecticidal soap solution, repot in fresh dry mix

Fine webbing between leaves; stippled, dull-looking leaf surfaces Wipe leaves with damp cloth; apply neem oil or insecticidal soap spray; increase humidity slightly

Larvae chew fine roots; adults are a nuisance around moist soil Allow soil to dry completely between waterings; use yellow sticky traps; apply BTi (Bacillus thuringiensis israelensis) drench
