I killed my musa basjoo by spraying dish detergent on it. I cut it down to the ground; in a week it was coming back up now it’s
about 12 inches tall but doesn't look like the original. What do I need to do? I sprayed it with dish detergent to kill mites -- a watered down version, but this killed it. I cut it down to the corm and replanted it. It grew back quickly but has thin leaves that grow out then break over. The stalk looks healthy and green but the leaves don't look right. Is it to early, or is it time to get another banana plant?

You would have needed to cut it back for winter so it may be OK. Here are instructions for preparing it for winter. I would wait and see how it does in spring. Then if it doesn't regrow properly, time for a new one.
