Hello! I have a little bed off of our deck and I would like to just fill it up with all different kinds of mint! The problem I am running into is that the soil is quite shallow and there is chicken wire or something not that far deep into the soil. I currently have some mint growing in there and it has spread through the garden bed a bit. I am wondering if I can just put a bunch of soil on top of the current mint and it will grow through the dirt or if I should dig them all out as best as possible.
