Creekweb,
Thanks very much for your informative explanation. The other varieties are Eureka,Giombo,Tanenashi, and two others that are unknown to me,which I know may complicate things. I do have many male native persimmons growing in the woods bordering my yard,some of them being as near as fifty feet or so from my Sheng. Is it a possibility that these natives have pollinated it? If this is the case,there isn't much that I can do about it,because there are so many of them. In any event,I will be looking at the kakis next spring for the male branches to satisfy my curiosity. As I have said,the seeds don't really bother me,I was just curious.

I suppose that if you live at the periphery of the native persimmon range you may have nearby 90 chromosome native trees that could theoretically pollinate the kakis, but in practice this has proven very difficult, and so the likelihood of this being the cause for the seeds is small enough to disregard. Besides, it doesn't fit the history of the sudden appearance of the seeds after years of seedless fruit.

It may be worthwhile to do a survey of your persimmon flowers next spring and label those branches having male flowers for future reference. The Tanenashi should remain seedless, and the yield on the Giombo, which is a light bearer, may improve with pollination.

That's what I will do. Your analysis makes perfect sense to me,and once again I thank you.

can you tell us more about your Sheng persimmon, is it heavy producer? How winter hardy is Sheng ? Does it produce fruits every year constantly? I bought Sheng variety this spring and would like to know more about it. Thanks for your review in advance.

First,I am in zone 8b/9a depending upon which chart you use,and it has endured temps as low as 15 degrees,as well as an ice storm a couple of years ago. Nothing as severe as some further north,but enough to give us concern. My Sheng had no problems with these conditions.
I have nothing but praise for the tree in terms of productivity and taste. I wouldn't say it is a heavy producer,but it produces more than enough,and it has been very consistent. One other thing is that it is a very attractive tree with an appearance unlike any other persimmon I have seen.
I think that you will be very pleased with your choice. Best of luck!

Thank you danaagillard, I am in zone 6b with temperatures down to zero F sometimes. So will see, if any winter damage occurs. How old is your Sheng tree and how many fruit it produces on avarage?I have seen some pictures of fruits and they look attractive. So your experience is, that pollinated fruit are sweeter than parthenocarpic. Is it late or midseason variety? If you paste some pictures of your tree, I will appriciate it. Do you grow other persimmon varieties in your garden?

I begin picking ripe fruit during late September,on the average. My tree is 10 years old,and has been procucing for 7 years. On average,I would say that I get about 50 to 75 persimmons.

Please see my earler post for varieties I grow. Sorry,I am unable to post pictures of my trees at this time.

Hi . Does anyone in here persimmon seeds varieties hardyzone 6 ?
