Leaf Burn on Holly Bushes

I have mature holly bushes at least 14 years old on the side of my house. After snow this winter, three of them have many black leaves all over. New growth is coming up, but the old black leaves are hanging on. What might I treat this with?

I would remove the black leaves, unless the black is caused by a sooty film and the leaves themselves are not black. Then I would treat for sooty mold. This article will help if it is sooty mold:
