June 3, 2011Q.Need Help in Identifying What Has Infected My Holly Bushes
The leaves are totally covered by a black substance, thought it might be tar spot but it completely covers the leaves, not spots. It's on leaves on bushes in both the front and back of house but doesn't appear on any of our other shrubs at this time. Trying to first identify this and then determine if it's treatable or not. Any input will be appreciated. Thanks.

Certified ExpertA.It sounds like sooty mold. This fungus is attracted to the honeydew from several different pests, so it is likely you have pests too. This article will help:

June 5, 2011Q.Diseases on Holly Bushes
We have both male and female hollies in our front yard. Recently the leaves have developed a white speckled growth on them. I thought it might be spider mites and used our hose to remove them. What might they be and what should we do to eliminate them?

Certified ExpertA.This sounds like sooty mold. Sooty mold is normally a result of a pest infestation, and the most likely in your case. Powdery mildew is caused by fungus that attack holly leaves, sometimes covering them entirely with a thin white powdery coating.

June 6, 2011Q.Insect Identification
I have a holly bush that is covered with sooty mold. On the underside of the leaves are fuzzy, very small white things that easily come off if I rub my finger over them. But the leaves are falling off and the plant is beginning to look sparce. The infestation is very heavy. I am worried about it spreading to other plants in my gardens. The problem seems to be going from the bottom of the shrub up.

Certified ExpertA.It sounds like you have mealybugs, which cause sooty mold. I would treat the plant with neem oil as this will treat both the pests and the fungus. Here is more information that will help you:
