This Week In the Garden
Holly Scale and Sooty Mold

This week in the garden UT Extension Agent Chris Cooper shows a holly tree that is infested by holly scale. As the holly scale feeds on the sap of the tree, it produces honeydew which the sooty mold – a fungus – grows on. Chris recommends using a soil drench with the active ingredient imidacloprid. This will control the scale. The sooty mold will then disappear on its own over time.
