What's eating my aglaonema gemini?

Aglaonema Gemini, a two-toned variegated cultivar, is prone to mealybugs and spider mites like all Chinese evergreens kept indoors. Scale insects can also establish on the petioles. Low indoor humidity in winter is the biggest trigger for spider mite flares. Routine leaf-cleaning and neem oil prevent most infestations.

Fluffy white residue in leaf axils and near the growing tip; plant grows slowly and leaves yellow Isolate plant; treat with isopropyl alcohol swabs then weekly neem oil sprays for 4 weeks; check roots if decline continues

Tiny pale dots stippling the leaf surface; fine webs visible on undersides; leaves lose lustre Rinse plant under the shower; apply neem oil or insecticidal soap every 7 days; maintain humidity above 50%

Hard brown bumps on stems and along petioles; sooty mould where honeydew collects Remove manually with alcohol and a soft brush; apply horticultural oil spray to kill remaining crawlers
