...what five years ???i cant wait that long. I can see my fully bonsai'ed tree with in 2 years...about wraping and then burying, waiting for two year blah blah, you dont have to do that. Using ficus binjamina just tye the tree in the sutable rock, put some clay soil and put the tree on a flat shallow dish and after a month on the shade you can now outdor the tree.
