I know the season is almost over, so I will not be too worried, as long as the plant will come back better than ever next year.
I am going to store the Musa indoors (in my cold cellar) over the winter. I plan to cut all the leaves off once they die off. I just hope this isn't the start of a final decline for this plant.
Have a look at the photos and let me know your thoughts.
Thanks,
Chris
