To destroy weeds for good in these trouble spots such as in
gravel drives and paths, add common table salt to vinegar. Just make sure to
never pour the salt mixture on soil, as the solution will make sure that
nothing grows in that spot again.
Drench the weeds with the solution on a dry, sunny day. Coat all surfaces well with the spray. Any plants soaked with this solution will die within several days. They won’t be back and nothing else will ever grow there.
