What's eating my aeonium castello-paivae 'variegata'?

Aeonium Castello-Paivae 'Variegata' is most threatened by mealybugs, which colonise the leaf rosettes and stem joints. Spider mites and scale insects also attack indoor specimens. Inspect regularly, isolate new plants, and treat early with isopropyl alcohol or neem oil to prevent colonies from establishing.

White cottony clusters in leaf axils and rosette centres; sticky honeydew residue; distorted, yellowing leaves Dab colonies with a cotton swab dipped in 70% isopropyl alcohol; follow up with neem oil spray weekly until clear

Brown or tan waxy bumps on stems and undersides of leaves; weakened growth; sticky honeydew Scrape off with a soft toothbrush; apply insecticidal soap or neem oil; repeat every 7–10 days for 3–4 cycles

Fine webbing at rosette base; stippled, bronzed leaf surfaces; premature leaf drop in heavy infestations Increase humidity slightly; wipe leaves with a damp cloth; spray with insecticidal soap or diluted neem oil
