I am not very knowledgeable about fruit trees and have had a few disasters. My apple tree hasbeen the worst bother - first year planted we got 2 very delicious discovery apples. Next year was hoping for great things but all the blossom went brown and fell off. I cleared all dead leaves and blossom away and put them in bin not in garden. Last year it has some strange white lines like wormy looking things on some leves - looking like a viral infection or something. We got 1 apple though rather than none the year before.
This year I'm hoping it will be OK but - noticed some silvery looking leaves (powdery mildew?) nd of one branch and cleared them off. Also loads of the blossom has fallen off but there are some very tiny fruits.
Shall I give up on this D* tree or is it saveable?
