We had about 10 persimmons this year on our small tree. Just as they were ripe, most were consumed by pests. (Wife’s relatives.)
Our tree is pretty prolific, but we don’t do any harvest for preservation, and there’s more than enough for us and whatever critters eat them.
Starting in September, I can get a few each day and they last well into November or December depending on the weather. Of course the later batch tends to me higher up and sometimes requires a ladder.
