scale on Philodendron
Quick answer
If your Philodendron has scale, the most likely cause is: Scale insects on philodendrons appear as clusters of little brown, gray, or white lumps on stems and leaf axils, where hard- or soft-shelled individuals pierce tissue and suck sap, gradually weakening the plant until it loses vigor and sheds foliage. Heavy infestations move from isolated spotting to systemic decline, especially in crowded indoor gardens where airflow is poor and natural predators are absent to suppress crawler settlement.
Start here:
- 1. Pick off individual scales by hand if only a few are visible on stems and leaf axils.
- 2. Scrub affected areas with a stiff brush dipped in strong, soapy water, then rinse the plant with clear lukewarm water.
