What's eating my rhaphidophora korthalsii?

Rhaphidophora korthalsii, a fast-climbing aroid, is primarily threatened by spider mites and mealybugs indoors. Its large, fenestrating leaves give mites plenty of surface area to colonise. High humidity and regular inspection of the undersides of leaves are the best preventive defences.

Yellow stippling and bronzing on leaf surfaces; fine silvery webbing on undersides and at nodes Shower the plant with lukewarm water to dislodge mites; follow with weekly neem oil or insecticidal soap sprays for three applications

White cottony tufts at leaf axils, nodes, and along the climbing stem; leaves may yellow and distort Swab colonies with 70% isopropyl alcohol; isolate the plant and apply neem oil spray weekly; repeat for 4–6 weeks

Silver streaks or scarring on leaf surfaces; dark frass specks; new leaves emerge distorted or with pale patches Remove heavily infested leaves; spray with spinosad or insecticidal soap, targeting undersides; use blue sticky traps to monitor population
