I would pot it up into a good free draining mix (slightly moist) at the same depth it was when in the ground. Leave it in a filtered light situation for 5 days and give a some water after 3 days.
Letting it rest in the new pot before watering will allow any damaged roots to heal prior to watering.

Our Jim had one he named "Long Tall Sally. It was one or two stems, taller than six feet! There are a few really old ones here on St. Croix that are six or seven feet tall. They eventually branch. Look like small trees at 30 years old.
