I used to get a box of organic produce delivered weekly, and a few times they included American persimmons. I was a little puzzled by them. I don't think the ones they sent were ripe, because they did not taste good. But... you have given me the thought to try again. Next time I see one, i will pick it up. Also, your grafting skills are impressive! I didn't even know such things could be done! Enjoy your harvest. All the best! :)
