Ok so long story short my potted bananas only trunk got broke off and then it started rotting so I pulled it out and put it in a vase. I washed the dirt off and cut the rot out and now it looks decent. I also made a clean cut because the top was starting to rot after it broke. It's in a vase of water now because I'm afraid to pot it. What should I do? I've had it for 3 years and I don't want to loose it.
