I have a peach tree, an apple tree, a plum tree and a sour cherry tree. The sour cherry tree is great. Usually gives us a bountiful harvest although this year am not seeing as much fruit as usual which I hear is normal for some years. The peach tree has had this issue for years with oozing and then the fruit drops off before ripe. The plums also seem to also drop off before fully ripened, although this year, I am seeing we still have some on the trees (a first). The apple tree does produce some apples, but they are misshapen and do not grow to a big size. My husband tries to spray with an organic spray, although the weather sometimes defeats him with rain. What do we have? I have enclosed a couple of photos showing the peach issue.
