Mealybugs are the white cottony clusters in leaf axils and on stems; isolate the plant and follow up for weeks.
Mealybugs sit as white cottony clusters in leaf axils and on stems. The plant is isolated; a small number of clusters is removed physically and the leaf and stem are cleaned. Honeydew can lead to sooty mold. Root mealybug can remain below the soil. One cleaning does not finish the job; follow-up takes weeks.
In a heavy infestation a product is not chosen before the label and the plant are seen.
Understand Phalaenopsis aerial roots, water uptake and potting mix before cutting roots, changing the pot or adding more fertiliser.
