Something is going on with my peach tree. Actually all my fruit trees. I haven't had one single peach to eat in past few years. I get lots of fruit in the spring though. But they fall off through out summer months until I have nothing left. The twigs have scab looking things. Reddish spots. The leaves get them too and then the spot falls off leaving a hole in the leaf. That gummy looking stuff you see in the picture is not all over the tree. Just on the few branches that I tried to graft into. Grafting didn't take. Just messed up the tree even more. The fruits had teeny bit of brown gum come out of it. What do you think is going on? And how do I fix it so I can eat few peaches off the tree next year? Thank you.
