What did the Romans do to destroy the fields of their enemys? You are correct. Salt. Salt will destroy all of the life in the soil for fairly long time. If you want to permanently get rid of weeds and everything else then salt is a great weed killer. Even a small amount of salt will affect the growth of plants. The best vinegar one can easily and cheaply buy is pickling vinegar which is either 10% or `12%. Regular vinegar is 5%. Horticultural vinegar is the best but it is expensive. It is 20% or 22%. But no matter which vinegar you use you still have to make multiple applications as vinegar kill the tops but not the roots.
So do we all! The stronger they get though, the more you risk the existing plants with overspray. Take the 2,4, D broadleaf killer for example. Not only is it a component in Agent Orange, but it is also a phytohormone that turns on all the plant cells and makes them grow uncontrollaby just like a cancer. Malformed sperm is a side effect of exposure. Its crap like that that makes synthetics a little unpopular around here. Plus 2,4 D does not kill grass of which you are sure to have some
Probably some ancient salt trauma from being invaded or some in-house warring! I want a back story! Of course an Island surrounded by salt water probably survives best if you do not sprinkle some more salt on top of the island!
Are you all being "prickly"? lolYes, I'm aware that Roundup is also a problem Daren. Likewise - I was reared amongst farmland and spent many happy hours as a youngster playing in over grown fields including bracken but I'm still here to tell the tale. You can hold on to your brambles thank you, I have some of my own but I'd be happy to swap the bracken for your nettles.
