Joe,
I did not know that.
Calvin,
Not a true biannual.....in the tropics the process probably takes a year. If you grew it up north it could take 5+ years.....all depends. As a rule the plant puts out a fairly set amount of leaves then it flowers. Sometimes they flower at the wrong time and are lost....I do get freezes here, 1-5 a year. That bunch is big but the bananas themselves should have been much longer, same size as grocery store bananas but the leaves got fried off this winter. The bananas still ripen though but won't get any bigger with no leaves to push them.
Right....when I cut the stalk down I just chunk it up and throw it back in the clump. It is a couple hundred pounds worth of stem. They actually make too many pups so have to kill a few off to keep the numbers down. Basically you have the king, or queen if you prefer...an heir and a spare. So you have the big guy a smaller 10' high right next to it and a small pup. There are 3 mains in that clump....bananas prefer to be in a clump and don't do so well by themselves.
