Hello! I would like to know what is the trick to get your banana trees to grow really tall? I mean so far I think I’ve only been able to get my older bananas to about 6’ or so. It is kind of funny b/c I bought it at 5’! I think what might have happened was it had a pup and all the water & food went to it and not the Mom! Any tips or tricks I’d be grateful for! Thanks!
