this is the problem with plastic its non porous no air can pass throw most plastics there are some that allow air transfer but they are exspesiv if you go back to the old days when people had to prep there non hardy plants for the most part they only used fibrous materials so i advocate hay and burlap they allow air to pass throw and slow transfer of moisture if your worried about dessication you can always spray any plant with and anti desiccant available at almost any garden supply cold and wet equals rot. cool and dry equals stable non bacterial condition also hay holds air pockets that insulate the ground and the plants them selfs it also repels water if its thick enough for example if you live in new england a proper layer of hay would be 3ft sounds like a lot but its not so don't skimp use an adequate amount the Bananas will be fine
