Hi, I'm new here. I live in south Florida and decided on a whim to grow bananas so I bought an "ice cream" pup online a couple years ago. It has been growing great and flowered a couple months ago. After all the bananas formed, I cut off the flower with a pair of shears. I was pretty disappointed with the number of bananas it produced but figured it was the first crop so maybe the future ones would be bigger. Anyways, shortly after I cut off the flower, the stalk started turning black from the end side. The rot started moving towards the trunk and the bananas were rotting as well. I decided to cut the trunk down today and hope the next one will be better. I tried looking all over the internet and couldn't find any reason for this. The only thing I could think of is the shears weren't clean and caused some sort of disease, since the rot began where I cut it. Any thoughts? Thanks
