    Hi Judy, In 1 gallon of white vinegar, add 1/2-1 cup epsom or table salt and about and 1/8-1/4 cup of Dawn. Shake well and apply with a garden sprayer or a spray bottle. Just be sure not to spray onto plants you want to thrive!

    Hi Judy: The recipe I use is:

    1 gallon of white vinegar

    2 cups of Epsom salts

    1/4 cup of dish washing detergent, like Dawn.

    Mix the vinegar and salt until the salt is completely dissolved.

    Mix in the Dawn until mixed well, but not all fuzzy and sudsy, sort of swirl it around.

    Put in a spray bottle and spray the weeds liberally, in the morning after the dew has gone. Then, by evening the weeds should be dead or on their way out. Don't spray anything you want to keep or it will die too. I have used this and it works quite well. Also, it's good for making an edging as it kills only what it touches. If you have something like a piece of cardboard, hold it up and down, edgewise, and spray the area you want as an edge. Just be careful not to spray your flowers and/or bushes.


    1 gallon white vinegar

    1 cup of salt

    1 Tbsp liquid Dawn

    Combine ingredients and put into a spray bottle and spray the weeds at the sunniest time of day.

    This mix is very effective so make sure it doesn’t spray on something you DON’T want to kill.

    This uses regular salt:

    2 cups white vinegar

    ¼ cup salt

    Squirt of dawn

    Mix in a spray bottle. If you have a larger area, you can mix in a garden sprayer with larger quantities. Use when it will not be raining for a few hours so that it isn’t washed away.

    1qt of white vinager,1/4 cup of salt 3 squirts of dish soap mix in a bottle and spray on weeds .ps it will kill what ever you spray on it

  • Epsom salt can work as a fertilizer rather than a killer in some instances so you might research a bit about the particular weeds you’re aiming to kill.
