Something is eating my banana...
I inherited a banana plant from my grandmother. I've no idea what variety it is.
It's been rather unhappy since I brought it inside for winter. First it had a spider mite infection but I think I got that under control with some spray. It perked up over Christmas but now it's looking unhealthy again. Can't see any evidence of mites. Also now has some evidence of chewing, see pics. Generally it's wilting, leaves turning brown starting at tips and edges
I can see little millipede-like insects in the soil, but I thought millipedes were harmless to plants. See pics again.
Please help if you have any suggestions.
