Peach Tree is Sick
My peach tree is suffering from curling leaves. The issue started last year and persists. This is a young tree and it only produced 3 fruits last season.
I suspected it's a fungal infection of some sort. So I read a bit of online research and decided to spray it with copper fungicide, which I did twice this Spring. Around the same time I also pruned the tree.
Within 10 meters (~30 feet) there is a cherry tree which is sick but seemingly in a different way. I am only mentioning it for the context.
Does the tree have a chance of survival? What should I do?
