My outdoor banana tree
The tree has grown fast and really well,new leaves unfolding all the time, but the lower and oldest of the leaves are black around outer edges and wilting. I've checked for pests. Trimmed bad leaves for mulch. Do I have a drainage issue? The last picture is one of the earliest. There's also a baby tree already growing in front, although it's too small to see. Thanks for your help.

I do believe this to be Black Sigatoka Disease.
