    Hi Laura, commercial vinegar has a higher acidic content than regular white household vinegar sold in grocery stores. Sprayed directly onto weeds will kill them within a few hours, just be sure not to overspray onto plants you don't want to kill. I often just use a large piece of cardboard to shield the other plants from the spray...(I use a small garden sprayer I purchased at WalMart for $5) t

    My recipe is 1 gallon of vinegar (I use grocery store vinegar which is about 4%) 1/2-1 cup of table salt and a squirt of Dawn dish washing liquid. Mixed together and placed in the sprayer. Since you're using commercial vinegar you may not need the additional ingredients.

  • Just place it in a pump sprayer and spray away. Be sure to protect any plants you want to keep, as "agricultural" strength vinegar is much more potent and has a higher acidity content. Apple cider vinegar and white vinegar are typically 5% acidity, "cleaning" vinegar is 6% and agricultural or janitorial vinegar is 10% and higher depending on the brand. Works like a charm, yet again, be careful. If you have sensitive skin, it can irritate it.

    I just soak the area and pull the next day...I need the exercise! LOL


    This is not an exact science – approximate measures are totally fine 1 gallon white vinegar and cup Epsom salts and ¼ cup liquid dish soap Combine ingredients in spray bottle and treat weeds at the hottest time of day for best results.

    Hi Laura: I just finished doing this and it works on shorter weeds, not the tall ones. Those just get aggravated:) The mix I used was:

    1 gallon of white vinegar

    2 cups of Epsom salt

    1/4 cup of Dawn dish washing soap. I guess any brand will do.

    I mixed the vinegar and salt together until the salt was dissolved and then added the soap and mixed that up. I put it in a sprayer and sprayed what I didn't want. It worked quite well on the weeds that were less than 3 inches tall, and I did a second spray the next day on the taller ones, but even though it didn't kill them, it made them fall over. This stuff is good for making an edge, too. Just don't spray it on what you want to keep. Good luck
