    I use white distilled vinegar, 1/2-1 cup table salt, and a squirt of Dawn dishwashing liquid. Mixed together, it makes a good weed killer. Just use a garden sprayer or a spray bottle to apply.

    Hello Helen: Here are some ideas and here's a vinegar/soap/Epsom salts formula:

    Borax, it's very helpful for killing unwanted weeds. All you have to do is add 10 ounces to 2 ½ gallons of water, mix thoroughly, and spray onto the weeds thoroughly. Watching them wither away smugly, optional.


    The proteins in cornmeal – or specially-processed corn gluten meal – stop any seed from germinating and growing. You can also sprinkle cornmeal on grown weeds, it’ll kill them just as well as it’ll stop them from growing.


    One quick way to get rid of weeds? Pouring or spraying a little white vinegar on the offending weeds. This acidic masterpiece is perfect for shriveling weeds, just be careful of your flowers. A little excess spray won’t hurt them, but accidentally pouring the same amount of vinegar on your flowers as your weeds could kill them. This did NOT work for me:(

    Or, what I have used with great success:

    Homemade Weed Killer:

    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.

    Good luck

    The weed killer with vinegar, Dawn & salt didn't do its job for long. The salt also crusted-up my pump sprayer so bad that I can get it apart a year later.

    5% vinegar is not strong enough by itself and higher concentrations are more expensive than a commercial herbicide. So that's what I use.

    Add dish soap and white vinegar to the salt solution and apply it on weeds daily to kill them. Pull out the weeds as soon as they die to prevent them from growing back. Use salt to kill weeds between pavers, in driveways, and gravel permanently. Applying too much salt on weeds will kill them permanently due to sodium chloride toxicity.
