Hi! Figs4Life,
1. For the tree that big, it is best to wait in early spring in 2014 before the leaves come out. Dig it up, and replant at your house. It will grow back fine.
2. If you can wait for all the leaves to drop in this fall, then you can dig it up and replant at your house, but you have to protect it in the winter otherwise it will die.
3. If you have to dig it right away or in a few days, I recommend the following:
Once you replant it at your house, you must cover the tree completely with a any thick fabric (fabric spreadsheets), any color white is better, but not black. Make sure you keep the fabric close to the bark. Everyday, keep spraying the water on the fabric to keep it moist at all the time during the daytime. You have to do this for at least 2 or more weeks.
Good luck to your new tree.
Best,
Tam
