I have a 5 year old peach tree bearing it's first real crop this year and it's starting to drop a few somewhat ripe peaches every day. I thinned a while ago, but I'm thinking maybe it was not enough and the tree is dropping the fruit it can't support. I've brushed the ants off of a few of the dropped peaches and eaten them, they were good (sweeter than I find at the grocery store) but had a slight bitterness and a bit of a green tint to the color. I don't want to let any of the peaches go to waste, but I also don't want to pick them too early. What should I do?
