Help! What's wrong with my banana tree?

I have an ice cream banana plant (I’m in zone 9b), and after I cut the fruiting tree down a couple of months ago, these two babies started looking pretty bad. They never seem to have recovered from the late winter frosts. New leaves are smaller than normal and look almost like they’ve been chewed… I’m not sure if it’s a disease or an insect. Usually this time of year the trees are producing tons of new healthy leaves. Even new shoots from the root system aren’t able to survive. What should I do?
Thank you!

This doesn’t look like pest damage. Do you have a lot of wind. The leaves look torn by wind damage. The yellowing and necrosis (dying tissue) at the edges may be to high salts in the soil or a lack of water. You could have a soil test done to see.
