Will the vinegar & epsom salts solution kill poison ivy & poison oak?

by Gail

In addition, will the vinegar & salt kill wild thorn vines? I need a very inexpensive solution that will kill these fast growing invading weeds I'm allergic to. I would gladly pour boiling water on them but distance carrying that water plus large area is just more than I can do. HELP PLEASE!

  • You need to cut down and dig out as much as you can before a vinegar solution will begin to work. They do sell "brush on" type weed killers, but I have never personally used them. I do it the old fashioned way, suit up, dig out, label the trash for the trash service guys so they do not get infected, treat the area, immediately take a hot shower then disinfect your clothes.

    It should make it strong with less water

    Thank you I will try that.

    There is no way I can dig the poison & thorny weeds out. It's all I can do now just to walk; neuropathy. Financially, buying weed killer is not an option either at this point in time. I already have salt & vinegar so will try it.

    Thanks again, Kathy!

    3 cups white vinegar

    1/2 cup table salt

    1 tablespoon liquid detergent or soap (I use Dawn) for stick-to-itiveness.


    1. Mix vinegar and salt until the salt is completely dissolved. Stir in liquid dish soap, and pour into a spray bottle.
    2. Spray onto the green growing leaves of the plants.
    3. Wait a week, then repeat on any survivors. Best time to apply: during a dry spell.

    Repeat as necessary.

    Chop it down (but leave a nub) and apply the salt mixture but you will probably need to repeat the process a few times.
