What's eating my philodendron autoclaw?

Philodendron 'Autoclaw' is a hybrid houseplant aroid. Like other indoor philodendrons it primarily attracts spider mites and mealybugs, especially when conditions are warm and dry. Quarantine new arrivals, maintain humidity above 50%, and check leaf axils and stem joints monthly for the earliest signs of infestation.

Tiny pale specks and webbing on the undersides of leaves; overall dullness and yellowing Spray forcefully with water to knock mites off, then treat with neem oil or insecticidal soap weekly; boost humidity

Fluffy white wax deposits in stem joints and at petiole bases; sticky honeydew and weak new growth Spot-treat with isopropyl alcohol; apply neem oil spray to the whole plant every 7–10 days until resolved

Adult gnats flying around soil; larvae chew fine roots causing yellowing and poor vigour Allow topsoil to dry between waterings; drench with Bti (Bacillus thuringiensis israelensis) solution; use yellow sticky traps for adults
