mealybugs on Anthurium
Quick answer
If your Anthurium has mealybugs, the most likely cause is: Mealybugs are soft-bodied insects that feed on plant sap, appearing as white cottony masses in leaf axils, stem joints, and root zones. They excrete honeydew which attracts sooty mold. On anthuriums, they often hide in the tight spaces where leaves meet stems. Infestations weaken the plant, cause yellowing, and can lead to decline if untreated.
Start here:
- 1. Isolate infested plant immediately
- 2. Inspect all leaf axils, stem joints, and base of plant for white cottony masses
