I've only had banana plants for two months and having been reading a ton since then. I've noticed that my "dwarf cavendish" isn't growing much, has big black spots on new growth leaves. I was inspecting the stem which had black streaks and felt soft in spots.
I decided to cut them to the ground today and here are the resutling pics. The questions i have are, should i remove corm entirely? what are the risks to my other banana plants in the vicinity?
