Hi - We are realizing how difficult it is to find organic peaches. We can a lot - 200lb this year, but they unfortunately were not organic. We have a large family farm in Vernonia (close to coastal range, in the mountains, so a bit cooler than the valley) and an in-ground greenhouse with 15ft ceiling height. It seems that it won't be realistic to have successful peaches outdoors. I'm looking for any guidance you might be able to provide on growing peaches (or maybe nectarines will be easier?) in an organic way. We like freestone for canning. I've read also about fan training and curious on whether we could grow a couple of trees in our large greenhouse and try to fan train them along the walls? Not sure if it would be too humid in the greenhouse, or whether the trees need to get down to freezing temps during the winter. Since our greenhouse is in ground, it probably won't get much lower than 40 degrees, even during very cold weather. We really want to have our own supply of these fruits - I hope you can help us!!
