Controlling Cytospora Canker
The needles on my decorative blue spruce are turning brown. Based on research I believe it is cytospora canker. If it is this disease how can I treat it? Is it possible it’s something else?

Thanks for your response. You say that the fungicide needs to be applied in May. So what do I do now that it’s July? Do I apply it anyway? If I do nothing now will it die?
