What are you putting it on? Does it kill everything or just the subset that you want? What's the mixture ratios?

If it worked on scotch broom I'd be forever grateful.

Thanks!

It definitely kills grass. I use it for both grass and weeds outside of the lawn. The recipe is from Pinterest of course but it's:

    1 gallon white vinegar (the kind we bought is 5% acidity)
    1 cup table salt
    1 tbsp Dawn dish soap

    Mix and pour into a spray bottle.

I'm not sure about scotch broom - reading says it's more effective on small weeds, but that it kills whatever it contacts. I think the salt is damaging to the soil, so don't spray it if you plan to grow something else.

Here's a paper I found with some info: https://extension.umd.edu//sites/extension.umd.edu/files/_do...

"I think the salt is damaging to the soil, so don't spray it if you plan to grow something else."

"Salt the Earth" is an established phrase in the English lexicon for a reason. The cancer-causing-ness of this mixture vs. Roundup may be in dispute, but this is certainly going to have a longer term effect than spraying Roundup, especially if you repeatedly apply it in the same place.

Thanks for the explanation and pointing that out. I wasn't aware until it was mentioned by you and another commenter.
