Hello everyone. I have a gardenia bush that is blooming now . It is four years old and this is the best it has ever bloomed. I was wondering where do you get Hollytone as you mentioned above. I had some black mold on the leaves. Black mildew I thinik it was. I sprayed it with copper sulfite, it seemed to fix the problem. I think too much water and poor air around it caused the problem. Here is a picture of it. I have used Miracal-Grow on it . I sprayed it once this year. Maybe need to do it again. Hollytone, might be better like you said. Where is it at. Thanks. Jeanae
