Is anyone able to tell me what kind of musa it is? Ive noticed that the bottom leaf has started to peel off the trunk, what does this mean? Also, should I be misting it daily? I can see a new leaf begining to unfurl, however the edges of the leaves are turning a bit brown and they look limp. What's wrong with it? So, for the size that I have, I can plant it in a bigger pot? 7 gallon? Thanks once again!!
