[Cathy] I buy 30% vinegar by the gallon from Lowe’s. It’s sold in the cleaner section. In an old (well rinsed) Windex spray bottle, I add about an 1/8 of a cup of plain table salt and about 2 teaspoons of blue Dawn. Fill the rest of the bottle up with the vinegar and gently shake to combine. I spray that on plants in the morning when I know it’s not going to rain. It’s even taken care of a patch of mint that suddenly popped up in the middle of my flower beds. You do have to be careful not to spray anything that you want to keep.

[Karen] Do you know if it destroys the soil? I have wild grasses growing in my flower beds and it’s almost impossible to get it out. This would be great as long as it doesn’t “salt” the soil so I can’t plant anything else.

[Cathy] The vinegar and Dawn should not harm the soil. I’m not sure if the salt is a snall enough  amount to not have an impact on the soil.
