How to Use Vinegar & Salt to control weeds

Vinegar has proven itself as an effective weed deterrent. Like most commercial herbicides, it is nonselective, not caring whether it effects weeds or petunias. Unlike commercial herbicides, vinegar is eco-friendly and will not harm people, pets, or the environment. Vinegar's only real drawback in certain cases is that it has no residual action so new weeds soon arrive. Permanent removal is occasionally desirable for stubborn weeds in gravel drives and paths as well as cracks and crevices in walkways and sidewalks. Add common table salt to vinegar to destroy weeds for good in these trouble spots. Just make sure to never pour the salt mixture on soil, as the solution will make sure that nothing grows in that spot for some time.
 
1 Pour 1 gallon of white vinegar into a bucket. Everyday 5-percent household white vinegar is fine for this mixture. You will not need higher, more expensive concentrations such as 10 or 20 percent. It may take two or three days longer to kill the weeds with the lower concentration, but they will die.
 
2 Add 1cup of common table salt to your mixture. Stir the solution with a long-handled spoon until all the salt dissolves completely.
 
3 Stir In 1 tablespoon of liquid dishwashing soap. This will act as a surfactant and make the vinegar and salt solution adhere to the weeds more efficiently. Blend thoroughly.
 
4 Funnel the weed killer into a plastic spray bottle.
 
5 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 will not be back because of the salt.
 
6 Funnel any leftover weed killer into an empty plastic container. Cap it tightly. Label it clearly and store in a cool, dark spot indefinitely.
