the longest distance i have transported a big banana is 500 miles. i just left some dirt around the roots and wrapped them to keep them moist.. but not air tight. i cut the heads off all of mine if they are big because they take up too much space,and they will be damage by the time i get to where im going anyways..they grow back fast, in fact i have had one push out a new leaf before i got home. i have never killed one yet.
if you want to save the leaves you will need extra space and will have to take extra care of them. sitting inside of a hot moving van may cook the leaves anyways. despite your hard work
