mealybugs on Philodendron White Knight
Quick answer
If your Philodendron White Knight has mealybugs, the most likely cause is: Mealybugs settle into the tight stem and leaf axils of philodendrons and feed on the sap, producing the white cottony clusters, undersized foliage, and spindly growth that the philodendron guide lists as the diagnostic condition for this pest; the dense, climbing growth habit of a White Knight with its tight internodes gives these insects especially protected hiding places.
Start here:
- 1. Dab each visible white cottony cluster with a cotton swab dipped in alcohol to dissolve the waxy coating and kill the mealybugs on contact, working carefully into every stem and leaf axil.
- 2. After spot-treating, wash the whole plant with a solution of equal parts water and alcohol, follow with a rinse of soapy water, and finish with a clear water rinse to remove any survivors.
