How to Make Weed Killer Out of Salt & Vinegar


Weed problems can exist in almost any lawn or garden. A common way to eliminate weeds is to spray chemical herbicides, but they aren't always effective, and the chemicals are typically harmful to the environment, animals and humans. Fortunately, there are many natural solutions for killing weeds. Two very effective weed killers are common table salt and plain white vinegar. Your weed problem can be taken care of with as little as one application of these two ingredients.

Step 1

Pour 1 quart of white vinegar and ½ cup of salt into a mixing bowl. Stir the ingredients with a spoon until the salt dissolves.

Step 2

Pour the mixture into an empty spray bottle. If necessary, use a funnel to ensure you don't spill the mixture.

Step 3

Spray unwanted weeds with the mixture. Use just enough of the mixture to cover the weeds with a light mist.

Step 4

Check the weeds three days after the initial application. If the weeds still appear to be alive and healthy, spray them with the salt and vinegar solution one more time. If the weeds are withered or brown, they do not need a second application.

Tips and Warnings

  • Salt may damage the soil and make it difficult for future plants to grow, so use with caution. The salt and vinegar solution may kill any other plants it comes in contact with.
