Out to in

Theres a plant i was growing out side.. didnt think it would live.. but now its a small little tree... its in dirt not a pot. how would i go about putting it in a pot with out killing the plant... and should i start budding it.. its def. vegged alot.. HELP!:)

The larger the pot the better, and be sure to take as much root WITHOUT disturbing them. I would then keep it under veg light, until it has gotten over the stress of having been replanted before I'd flower it.
