  • For weeds, I use straight vinegar in a spray bottle. However you have to be careful where you spray it, because it's not discriminating. It's effective, it will kill everything, not just weeds.

    Make a poison ivy killer spray: Combine 1 cup of salt and 1 gallon of vinegar in a pot and heat to dissolve the salt. Allow it to cool, then add and 8 drops of liquid dish soap and put the mixture in a spray bottle. You can spray the poison ivy or pour it directly on the plant. This will kill all vegetation, so be sure to only apply it to the poison ivy.

    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.

    3 cups white vinegar

    1/2 cup table salt

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

    Directions

    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.
