I found the course of my root maggot problem, I had some hemp seeds growing (the kind you get at the health food store) The hemp is completely ruined now by the root maggots I've had that same problem before when growing various vegetables in the past where they always get attacked by root maggots but interestingly enough my other plants such as my fruit trees get left alone, I just hope they don't end up attacking my banana plants as there a kinda herb, hopefully touch wood they'll be ok.
