My Sugarcane set the yr it was planted in Alpine, TX. Li was much slower. I had about 6 varieties for pollination. So don't know what your issue might be. Grafting on more varieties is all I can suggest.

They should be self-fertile. humm.. Sounds downright scary, but I have heard that a great way to force them into bearing heavily is to stress them a bit by gouging the trunk.. some Chinese farmers cut the bark of Jujube trunk - it somehow sparks a reproduction response in the plants and helps prevent the tree from dropping fruit.. it is a technique that has been used (supposedly) for centuries. Here is a link http://v.youku.com/v_show/id_XMTMyNDEwMjY4.html. It is in Chinese, so I have NO IDEA what is happening other than they are scoring the trunks.. research it!

I did a quick google search and the technique is called "Girdling" - https://en.wikipedia.org/wiki/Girdling

Obviously I'm not suggesting the girdle the entire trunk of the tree (that would kill it) - just a small bit.. any others with experience here would be appreciated if they could chime in..

Very interesting Daniel! I should report as a follow up that I did recently find two jujubes on the sugarcane. They are still immature, and I'm thinking they were not set until quite recently, but I'm optimistic they will ripen before first frost.

Incidentally, I will probably wait another year before getting bent out of shape over no jujubes from my trees. I have since added another good-sized Li, so things should work out eventually I guess.

Thanks for your info...

Hi, did you ever find out the solution? I have a Jujube tree that was inherited from the previous owner of my home. It is a beautiful, healthy tree with flowers everywhere (it's been flowering for months), but no fruit.
