I am having some trouble with my evergreen bush and need some help identifying whats wrong with it. We had a really tough winter last season it snowed more than usual, which really weakened many of my plants. Ever since then half of the leaves on my evergreen bush refused to grow back properly. I checked it and found black things growing all over its trunk and branches. I sprayed fungicide on it thinking that it was a fungus and left it alone for a while, but it's still sick I do not want it getting my other bush sick or my apple tree help!
