Problem Info

Crusty, waxy, or scaly bumps cover stems or leaves. They''re brown, yellow, or white, and can be scraped or picked off. Leaves turn yellow and may drop. In some cases, a shiny or sticky substance coats the leaves. A black sooty mold often grows on the sticky substance.

Solution Advice

An uncontrolled infestation of scales may kill the plant after 2 or 3 seasons. Spray with an insecticide labeled for these pests, following label directions.
