How to Make a Nontoxic Weed Killer

By: Joe Truini
dish detergent, vinegar, epsom salt

Use these ingredients to make a nontoxic and inexpensive weed killer.

To make an affordable, nontoxic weed killer, use a funnel to add 1/2 cup of epsom salt, a quart of white vinegar, and a few squirts of dish detergent to a spray bottle. Shake it up and spray directly on weeds. The detergent will help it stick to the leaves. Within two or three days, the weed will dry up and die.

    I’ve had success with boiling water, boiling water with salt in it, and white vinegar.

    I need something drastic but safe for dogs to kill Creeping Charlie, aka Jill (gill) over the ground, aka ground ivy. It’s everywhere. I spent one summer pulling up every speck of it and it didn’t make any difference. I know that even the tiniest bit of root or stem will create a zillion new plants.

    Bind weed that came in with a load of soil is also plaguing us. Any advice?

    J Stephens, regular white vinegar should work fine.

    Cindy, yes, this formula could kill (wanted) plants as well as weeds; so be careful when spraying!
