Salt Water to Kill Weeds
I hope some one can advise me. I have just had a new lawn laid and left a .6 metre border around the edge. There seems to me a proliferation of fern style weeds particularily on one side. Some are even poping up on the lawn. I have dug them up and found a network of huge roots. Even after this they come back as there seem to be large white egg stlye seeds or pods.
I want to put a weed mesh down and cover with decorative stones on top so I don't need anything to grow in the border and was told if I put boiling water with salt around the border ot will kill all weeds at the root. I am just worried the wasl and water will seep into the lawn and kill that just after I have paid a fortune for it.
Any advice gratefully appreciated.
