How to Use Salt Solution to Kill Grass


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.

Step 1

Mix 1 cup salt, ½ cup vinegar and 2 cups water in a pot.

Step 2

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.

Step 3

Pour the salt water into a spray bottle. If necessary, use a funnel to make it easier.

Step 4

Spray the salt water on the unwanted grass. Be careful not to get it on any plants that you want to keep.

Step 5

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.
