Wow- you really went all out on these trees. There is no way I could do things that nicely and still plant as many as I do. My lucky ones get a couple logs or landscape laid down for a slightly raised bed, but now I basically take a few shovel-fulls of dirt out, plop the tree in, and spread woodchips around it. .
What spacing did you use? It looks like a decent amount- maybe 12'? You probably won't have to as harshly prune them as I will likely need to. I used 5' spacing for my new planting this year. I added quite a few this year:
Shanxi Li- 2
Some of these are dupes of what I've grafted. You can see that I like So a lot, since I got 3 more of them, even though it is already my most mature jujube. It combines good fruit with compact growth.
I think you'll like them. When I brought some into work last fall, I don't think there was anyone who didn't like the ones I grew. Crisp, super-sweet fruit- what is not to like? The ones grown by Roger Meyers in a hotter dryer climate didn't have the same snappy crispness to them, but I was a bit surprised to see that several people really liked them as well. And you can always tell your husband that you need a couple extra for pollination
I've noticed that the smell is like grape soda. I'm not sure I'd say it is the best, (I like the Satsuma plum), but it is nice.
