Recently, a mixture of vinegar, Epsom salts, and dish soap has become all the rage in fighting weeds found in the garden and yard. It’s partially attractive as a remedy as it avoids the use of harsher chemicals on your property, and because it actually does work. Using a treatment made of vinegar, Epsom salts, and a liquid dish soap such as Dawn will kill weeds in your lawn, but it also depends on the concentration of your solution and when you apply it. By creating a strong concentration and using it only on the problem areas when the sun is out, you can dry out the weed leaves and kill the plant over several applications, particularly if it’s a hardy one like quackgrass or crabgrass.
