What's eating my calathea concinna?

Calathea Concinna (Freddie) is primarily affected by spider mites in low-humidity conditions, followed by mealybugs hiding in the pale-striped leaf folds. Fungus gnats can also breed in its moisture-retentive compost. The key defence is maintaining humidity above 55% and never leaving the plant sitting in stagnant wet soil.

Fine webbing and pale speckling on leaf undersides; the crisp green-and-white striping fades and leaves curl Raise humidity; shower the plant; spray insecticidal soap or neem oil weekly until no further signs appear — typically 3–4 treatments

Cottony white deposits in leaf folds and axils; honeydew makes the leaves feel sticky Apply isopropyl alcohol directly to colonies with a cotton swab; follow with a neem oil spray; quarantine and re-inspect weekly

Adults fly near the soil; larvae chew roots, causing yellowing and stunted growth Let topsoil dry between waterings; drench soil with a Bti (Bacillus thuringiensis var. israelensis) solution; use yellow sticky traps for adults
