How to control scale insect on Holly
I have a tall Holly tree about 25' in front of my house and it is loaded with brown scale insects under the leaves. The leaves are covered with honeydew, and sooty mold is growing. How do I control it?

I would recommend treating the bush with Neem oil, as it will take care of both the scale insects and the sooty mold issue. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/scale-bug-how-to-control-plant-scale.htm
