I have a mini dwarf nectarine tree. Last year all the fruit feel off and rotted before it was ripe. This year the fruit is starting to do the same thing. The fruit is getting big and almost ripe then it will start to rot on the tree. I have included pictures of three of the nectarines I pulled off today. The fruit is also spotted. Is this some sort of fungal disease? What can I do to stop it or prevent it in the future? Any help will be greatly appreciated.
