What is a non-toxic grass killer to kill a lawn?

Answer by  Ella22 (610)

For large areas, use a black plastic tarp. You will need to leave it down for a couple of months. For smaller areas, use vinegar or salt. Some recipes call for dish soap, vinegar, and boiling water poured directly on the grass. For grass in crevices that is stubborn, use fire such as a torch to burn it out.

The best thing can be straight salt - pickling salt right from the box. You can also use vinegar. You can burn the grass - it's a small space.

If you want something organic vinegar will kill your lawn. I put it on weeds and grass that grow in between the sidewalk crackers when the sun is shining. Vinegar works, it is slow but it is non toxic. Also you can suffocate the grass. Just put with plastic over it for a few days.

A very easy way to kill a small lawn is to cover the area with heavy sheet plastic and secure it around the edges. Leave the plastic on the grass for a few weeks, or longer if needed. This will smother out the grass and kill it!

One way that you should be able to kill your grass is with Boric Acid, also known as Borax. This should dehydrate the lawn without exposing your yard to any toxic chemicals. This may not be a great idea, however, because it will take some time before you can grow anything else there.
