Just my two cents, but this late in the season to dig a plant up? The chance of success is very low at best, the chance for severe shock, a sure bet. The other problem I see would that if it is that close to a tree how do you propose to get a root ball out that is bigger than the diameter of the plant? IMHO at this stage in the game I would take light airy buds to no buds. Just mark it up to a lesson learned. Best of Luck to youMine were too... You have to be careful and dig deep enough to get the root ball out intact.
