What's eating my rhaphidophora decursiva?
Spider mites
Signs: Pale stippling and fine webbing on leaf undersides; leaves may dull, yellow, or develop a bronzed look in heavy infestations.
Control: Shower the plant and apply neem oil or insecticidal soap to both surfaces of all leaves every 5–7 days. Raise humidity above 60% to suppress reinfestation.
Thrips
Signs: Silver streaks and scarring on leaf surfaces; tiny dark droppings (frass) visible on leaf undersides; distorted or necrotic new leaves.
Control: Apply spinosad or insecticidal soap weekly for 4–6 weeks. Deploy yellow sticky traps near the plant to capture and monitor adult thrips. Remove heavily damaged leaves.
Mealybugs
Signs: White waxy cottony masses at stem joints and the base of large petioles; honeydew deposits and slowed growth.
Control: Dab colonies with 70% isopropyl alcohol swabs. Follow with weekly neem oil or insecticidal soap sprays for 3–4 weeks. Keep the plant isolated.
