Although grass is a basic part of any homeowner's landscape, it can sometimes grow in unwanted locations. Grass can grow cracks or crevices in driveways, sidewalks, mailboxes or just about anywhere. To kill grass patches, consider a homemade grass solution. Chemical grass killers are not safe to use around children and pets and are not good for the soil, either.
Pour one gallon of vinegar into a small bucket.
Chop up the three garlic cloves and dump them into the vinegar.
Set the garlic-vinegar mixture aside for 24 hours.
Strain the pieces of garlic from the vinegar with a piece of cheesecloth and discard them.
Add 1-1/4 cups of salt to the bucket and mix it until it dissolves.
Pour the homemade grass killer into a spray bottle. Spray over the areas of grass that you want to kill.
