    Hi Billie: What I use is this:

    If the weeds aren't over about 4 inches tall, (unless you really soak them) you can make a mix of:

    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 dissolved, mix in the Dawn until mixed well, but not all fuzzy and sudsy.

    Put in a sprayer 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 done this and it works. 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. Good luck


    1 gallon white vinegar

    1 cup of table 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

    just use straight vinegar pour on weeds into center of plant so it soaks down into roots during hot full sun no rain for at least 3 days or you'll need to repeat. anything else will make your dog sick if he licks it including dish soap it is toxic,it won't kill him but can make him very ill and cause minor to severe skin irritation(feet) and posible allergic reaction by getting in/on nose or inhaling. Is salt bad for dogs and cats? YES! Salt toxicity in dogs and cats can result in death if left untreated. causes severe dehydration

    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.

    I think this will be ok, but check with the vet to make sure:

    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.
