Green, healthy grass is important to make a lawn look beautiful, but it can be a nuisance when it grows in unwanted areas. Places such as cracks in sidewalks or driveways and gardens are susceptible to sprouting up unwanted grass. A common solution to this is to spray an herbicide on the grass, but not everybody likes to use chemicals on their property. The next best option is to use a salt solution which is just as effective as chemical herbicides.
Mix 1 cup salt, ½ cup vinegar and 2 cups water in a pot.
Put the pot on a stove and bring the liquid to a boil. Stir the mixture with a wooden spoon to help the salt mix in with the water. Remove the pot from the heat and let it cool down for five minutes.
Pour the salt water into a spray bottle. If necessary, use a funnel to make it easier.
Spray the salt water on the unwanted grass. Be careful not to get it on any plants that you want to keep.
Repeat the process every other day until the grass dies. One application is often enough to get the job done, but it may take more attempts.
