We recently bought two banana plants, and two days after arrival died (dried whole leaves), of course not the fault of Seller, healthy roots disturbed during transportation.
With advice from this forum I saved it.
Half of the roots were rotten, I have changed the soil and leave it, chasing it every day.I'm sorry but I have no photos.
After 3 weeks of waiting I saw tilts to one side (a sign that living roots on that side a pull down), then I started to cut stem up to an inch of ground where I found healthy tissue.
DO NOT throw the plants if you are not sure is dead.
Thanks to everyone on this forum.
