John, it's really hard to see trees upside down. LOL! BUT, all UCD trees come infected with FMV which, in your zone, would make things tough. They should grow out of it with age, but they might need more fertilizer and care. In my zone, 9b, FMV is not a problem. I do have FMV free trees, and they don't seem to catch the stuff, but my trees are spread over 1.5 acres and all in ground once they go dormant in a 3 gallon container. IF they go dormant, which this year, nothing did.
I'm certain yours will root GeneDaniels! Good luck!
