I have a corkscrew willow that I planted a year and a half ago. The tree has done beautifully until I noticed today that it had some yellow leaves. So I got closer to inspect and I believe it has black spot :(. Is there anything I can do? I know on roses you remove the leaves and spray the entire plant with a fungicide. But obviously that is one very daunting task with a 12í tree. I live in Clayton, NC and it has been insanely rainy this spring so Iíve been fighting black spot on my roses. I might have given this to the tree since I just pruned it two days ago. :( any advice would be helpful.
