7 Organic Weed Killers you can make at Home

1. One quart white vinegar
¼ cup salt
2 tsp vegetable based liquid soap

In a bucket, mix one quart of white vinegar with ¼ cup of salt. Stir till salt dissolves. Slowly add two teaspoons of vegetable based liquid dish soap. Gently mix and pour solution in your garden sprayer.
Spray directly on the offending weeds at the base using the narrow stream setting. Best if used in direct sunlight and when rain is NOT in the forecast. This organic alternative to Roundup Weed Killer works well for those weeds growing in sidewalk cracks.

2. 3 quarts white vinegar
1 quart vegetable based liquid soap

Pour three quarts of white vinegar in a bucket or directly into your garden sprayer. Slowly pour in one quart of vegetable based liquid dish soap, gently swish to mix.
Spray on leaves and the base of the plants, again using a narrow stream. Be sure to spray only the plants you wish to kill as this is not a selective organic weed killer.
Do not water for three days. Reapply if rain falls before the three days are up.

3. 1 quart water
1 tbsp rubbing alcohol

Pour one quart water into your garden sprayer and add one tablespoon rubbing alcohol. Spray the undersides of the weed you want to kill with a thorough light mist. Again, use care not to spray non-target plants. Increase alcohol content for stubborn weeds.

4. Here is another organic alternative to Roundup Weed Killer for weeds that grow in the cracks of your sidewalk only.
Lightly spray sidewalk weeds with water. Sprinkle weeds with a light layer of table salt. Lightly wet the weeds again. Be sure not to use too much water, you don’t want to wash off the salt or cause runoff.

5. Boiling water method:
This is the simplest organic weed killer. Boil water in your tea kettle, pour it directly on the offending weeds. Be sure to pour close to the weed to minimize splatter and use just enough to cover the weed(s).

6. 4 quarts distilled vinegar
1 cup salt
1 tbsp vegetable based liquid soap
Place four quarts of distilled vinegar in a large pan and heat just until it begins to boil. Turn the burner off. Avoid directly inhaling the fumes. Although they are not dangerous, the fumes from heated vinegar can be overpowering.
Add one cup of salt and stir until the salt crystals are completely dissolved.
Add a tablespoon of dish detergent to the solution and mix well. The dish detergent serves to help the solution adhere to leaves and stems long enough for the vinegar and salt to kill the plant.
Allow the solution to cool and pour into a spray bottle. Apply directly to the plants you wish to kill. This solution will kill any vegetation it comes in contact with.

7. 1 gallon white vinegar
1 oz orange oil
1 oz vegetable based liquid soap

Fill a bucket with 1 gallon of white vinegar, Add 1 ounce of orange oil, Add 1 ounce of liquid dish detergent. Pour the mixture into a large spray bottle. Shake before use, as the oil will separate.
Spray the mixture on the weeds you wish to kill. Be careful to spray in very targeted area, as this mixture will kill any foliage it touches.
