Wilting White/Brown Leaves on Banana Plant
I have a 4-year-old dwarf Cavendish that had to spend last winter in a less-than-ideal location in my walk-out basement, so it started this year out puny. It is shown in the third picture. It was growing well and grew several new leaves within the last month. I have moved it to a larger container and to a sunnier location outside, but it has not done well for the last week, and you can't really tell that it is growing.
I also bought a new small banana plant, but I am not sure exactly how old it is. I have had it about a month. It has recently developed white, wilting leaves, and I don't know why.
I live in central North Carolina, and it has been in the low 80s for the past week. About two weeks ago, it got down near freezing, but I covered both plants in blankets, and it warmed up later that day. Any help that anyone can provide would be greatly appreciated.
