Interesting that your trees are holding on to their fruit. The trees I have access to are just a few miles away from yours (I am less than a mile from Callaway County), but all my persimmons dropped weeks ago. I have access to probably thirty different trees across 150 acres with several different orientations and micro-environments and they are all devoid of both fruit and leaves.
Yeah, even out in the woods where I go, the different patches that I visit are in very different stages of ripeness. In fact, there is one tree off by itself that is not even ripe yet, and several that are almost done dropping their fruit for the season.
