Before I even saw your question, I just happened to be out inspecting both my jujubes today. I looked pretty closely and I didn’t see a single fruit yet. However, keep in mind that I actually got fruit off both of my trees last year (1 from 1, 2 from the other) and I’m 99% sure that they didn’t set by this point either. And just as @k8tpayaso says, they are still blooming big-time so there is still a good chance something will set. You didn’t mention anything but HJ- and I’ve forgotten, did you also get a Sugar Cane like I did? If so, has it set any? Mine hasn’t but it is still blooming as well.
BTW…what about growth, Zack? Both mine are absolutely growing like Crazy. I might even give Kate a run for her money with the growth I’ve seen the last couple weeks, and that is saying something!!! ha. I actually put about 2 handfuls of 10-10-10 granules around both my trees about a month ago, so I’m not sure if that is what created this spurt or if it is just typical 2nd year growth, but I honestly think my HJ has put on 2 feet in 3 weeks. Undoubtedly the fastest growing tree in my orchard right now-both of them.
