I have recently planted (couple years ago) Contender Peach trees - one has taken off and the other never has. I live in East Liverpool OH and last year noticed my fruit was spoiling and turning dark with all my leaves looking like this. I've yet to get a harvest as my tree wasn't mature enough until last year. I sprayed Bonide Fruit tree spray last fall/winter and now I'm wondering what else to try. It doesn't seem to have worked at all. Any suggestions?
