Controlling Useful Invasives
I wanted to put this under a gardening section, of which there is no category specifically dedicated to that general subject.
I was reading the stinging nettle thread and this made me think, what have you successfully done to try to contain an invasive such as stinging nettle, other mints, comfrey (if you want it contained), etc.?
Pots have already been suggested. Harvesting before seed formation has also been suggested.
I have a washing machine tub that I would like to use for invasive containment. It would make for a lot of digging down into the ground and then filling, but I think that it could be worthwhile as it should at least contain wandering roots. Thoughts?
Any other ideas are welcome. I would like to know what others have done.
