Gardenia Leaves Turned Black

Anonymous added on March 6, 2011 | Answered

I have two gardenia bushes planted outside that produce a lot of blooms. Suddenly the leaves have turned black with a crispy black film that looks like it is peeling off on some of the leaves. What is the cause of this, and is there something I can do to correct it?
