mealybugs on Philodendron Congo
Quick answer
If your Philodendron Congo has mealybugs, the most likely cause is: Mealybugs appear on philodendrons as white cottony clusters tucked into stem and leaf axils where they pierce the tissue and suck sap, which stunts new growth, deforms leaves, and leaves foliage undersized and the plant looking spindly and weak overall.
Start here:
- 1. Dip a cotton swab in rubbing alcohol and touch each visible white cluster to dissolve the waxy coating, then rinse the foliage with a gentle stream of clear or soapy water and follow with a clear rinse to remove any residue.
- 2. For a heavier infestation, spray the entire plant (including leaf undersides and stem joints) with a horticultural oil or insecticidal soap labelled for indoor use, repeat every 7 to 10 days until new growth emerges clean, and isolate the plant away from neighbouring houseplants during treatment.
