What's eating my golden mosaic ctenanthe?

Golden Mosaic Ctenanthe is most troubled by spider mites, which thrive when humidity drops below the plant's preferred level. As a Marantaceae relative, it also attracts mealybugs in its leaf sheaths and fungus gnats in consistently moist soil. Daily misting, grouping with other tropicals, and a well-draining mix prevent most infestations.

Fine pale stippling on the yellow-and-green patterned leaves; webbing on undersides; leaves may curl in low humidity Boost humidity with a humidifier or pebble tray; spray neem oil or insecticidal soap every 7 days for 3 weeks

White cottony deposits inside leaf sheaths and stem joints; honeydew and sooty mold on lower leaves Remove mealybugs with an alcohol-dipped cotton swab; spray diluted neem oil over the whole plant; repeat weekly

Tiny black flies hovering at soil surface; larvae graze roots, causing wilting in heavily affected plants Allow top inch of soil to dry between waterings; apply Bti drench; use yellow sticky traps to monitor adults
