Chemical-Free, Homemade Weed Killer


  • 1 gallon of white vinegar (higher acid vinegar, such as 20% vinegar)
  • 1/2 Cup Citric Acid powder
  • 1/2 cup salt
  • Liquid dish soap (any brand)
  • Empty spray bottle

Put salt in the empty spray bottle and fill it the rest of the way up with white vinegar and citric acid. Add a squirt of liquid dish soap. This solution works best if you use it on a hot day. Spray it on the weeds in the morning, and as it heats up it will do its work.

Make sure you only get the weeds, otherwise, you will kill plants and grass.

      Hi Rachel,
      I apologize for not putting the amount of citric acid. Honestly, I didn’t realize it wasn’t in there until you wrote me. Sorry for the confusion.

      1/2 cup citric acid for the recipe.
