Holly turned totally black

Anonymous added on June 8, 2016 | Answered

My holly bushes have turned totally black. The leaves are black and the branches also. There is a white fungus on the back side of some leaves. Is the plant savable, no green left. Thanks for your help.

It is possible that it is scale or mealybugs, which produce honeydew that attracts sooty mold fungus (the black you see). I like to treat both with neem oil. It is very effective and safe. It will also help treat the sooty mold problem too. These articles will help:
