What's eating my chamaeranthemum venosum?

Chamaeranthemum venosum, a low-growing tropical foliage plant, is most threatened by spider mites, which thrive in warm, dry indoor air. Mealybugs and fungus gnats also attack it. Keep humidity high, inspect leaf undersides regularly, and isolate new plants before introducing them to your collection.

Fine stippling on leaves, silvery webbing on undersides; leaves yellow and dry out Raise humidity, mist foliage, wipe leaves with a damp cloth; apply neem oil or insecticidal soap spray weekly until clear

White cottony masses in leaf axils and along stems; sticky honeydew and sooty mould follow Dab colonies with a cotton swab dipped in 70% isopropyl alcohol; spray with insecticidal soap or neem oil; repeat weekly for 3–4 weeks

Larvae chew fine roots in moist potting mix, causing wilting and slow growth; adults are a nuisance near soil Allow the top 2 inches of soil to dry between waterings; use yellow sticky traps for adults; drench with Bacillus thuringiensis israelensis (Bti) for larvae
