What's eating my codonanthe crassifolia?

Codonanthe crassifolia is a tropical gesneriad grown indoors, typically as a hanging plant. Mealybugs are the most common pest, infesting the fleshy stems and leaf joints. Spider mites and aphids also attack, especially in dry indoor air. Regular misting and prompt treatment with neem oil keep this plant healthy.

White waxy deposits at stem nodes and leaf undersides; honeydew leads to sooty mold; plant growth slows. Apply 70% isopropyl alcohol with a swab to colonies; spray neem oil solution weekly until no signs remain.

Fine webbing on stems; yellowing, speckling leaves; worst in hot, dry conditions indoors. Rinse plant with lukewarm water; apply neem oil or insecticidal soap spray; raise ambient humidity.

Clusters of soft insects on new growth tips; sticky honeydew residue and curled, distorted leaves. Knock off with a strong water spray; apply insecticidal soap or neem oil; repeat weekly for 3 weeks.
