Q.What’s Been Eating My Banana String
I’m not sure but I think grasshoppers have been eating it, is there anything I can do to prevent that? And does it look like it’s been enough water?

It very well could be grasshoppers! They can be difficult to control, and insecticides are just barely effective if you use them constantly. In this case, I would go with microbial warfare. Nomesa Locustae is a neat little single celled organism that will infect grasshopper and kill them off quite effectively. It is harmless to you, but will protect plants very well. You might try your local garden centers, but you may end up having to find sources online.
