grayish cement-like mold?
Hi! I've been searching the forum and other web sights trying to see if I can assess what is growing on the plants in my front yard. It is a mold or fungus like growth. Looks like someone splattered thin cement on the branches. When dry it is gray, when wet it has a slight green cast to it. All the inside branches of my bushes are not producing leaves or flowers. I thought I'd found it when I saw a pic of lichens. But, mine is not at all 3D. It is very flat, hugging the bark in small spots that grow together to form larger areas as time goes by. it started on the lilac close to the house, it was on that for a couple of years, as the lilacs inside branches declined. I figured the area to be too shady, maybe not enough air circulating. Now it has invaded my plum, father out in the front yard and my forsythia on the other side of the front. If it is indeed lichens, and they are not harmful, what can I do to help out these plants before I lose everything in my front yard? The others should have no problems with air circulation and seemed healthy otherwise. Is there another type of harmful fungus or mold that looks somewhat similar to lichens? Does that "Bayer" tree and shrub stuff really do any good? or something similar? I really cannot see any other problems with these plants!
