I have a potted dwarf apple tree that we really want to save. I am currently working on stopping and treating the powdery mildew. I’m afraid it also might have fire blight. I remember some of the leaves wilted away but was still attached to the stems and I believe I read that was a symptom or sign of fire blight. I have attached some pictures if I could get help identifying any diseases, etc. and most importantly any suggestions on how to treat or what to do. Thank you in advance!
