Precautions for Natural Weed Killer Applications

Natural weed killer solutions can be just as damaging to your desired plants as they are to weeds!

Always use precautions when applying any weed killer.

  • Watch for lateral drift when spraying. This is when the weed killer droplets move side-to-side, causing unintended damage to your desirable plants.
  • Cover desirable plants with pots or buckets to protect them from any direct or lateral spray.
  • Do not spray plants when the wind is blowing to protect all the desirable plants and vegetation.
  • Always try a small test area first to make sure your DIY weed killer recipe is working properly.

1. Vinegar, Salt, and Dish Soap

Each of these three ingredients has unique properties that combine to kill weeds. For example, both vinegar and salt contain acetic acid, which will cause the weeds to dehydrate.

The acetic acid breaks down the cell walls of the weeds, and the internal fluids begin to leak out slowly.

Applying vinegar or salt alone is an effective weed killer, but dish soap accelerates the process, so the weeds die faster.

The liquid dish soap softens the weed’s foliage and stem, so the acetic acid quickly enters the plant’s pores.

To make this DIY weed killer, mix one cup of salt and one tablespoon of dish soap into one gallon of vinegar.

  • Gallon White Vinegar
  • One Cup Salt
  • 1 Tablespoon Dishsoap

Dissolve the salt in the vinegar first, then add 1 tablespoon of dish soap. Remember, if you shake this mixture, it will have bubbles from the dish soap!

Mix well, then pour the mixture into a spray bottle for easy application. Saturate weed plants with this natural dehydrating mix.

2. Salty Water

Mix 1-part salt to 2-parts water.

Salt water works well as a natural weed killer.

Stir until the salt is completely dissolved. Put it in a spray bottle and saturate the weeds. The soil will remain fertile after the weeds are killed by diluting the salt with water.

You can pour table salt directly onto the weed. However, leaving too much salt on the ground and in the dirt will hinder future plant growth in that spot for a few years.

Saltwater is fine for walkways, driveways or other cracked concrete surfaces where vegetation is not desired.

For a more robust solution of salty water for weeds in sidewalks, driveways or where you will never be planting, mix 2-parts salt to 1-part water.

3. Lemon Juice and Vinegar Spray

Lemon juice is an effective and safe weed killer. The citric acid in lemons will burn the leaves and cause the plant to dehydrate.

When lemon juice and white vinegar are combined, it creates a more potent weed killer that will kill the weed within two days.

This weed-killing recipe calls for the juice of two lemons to be combined with two cups of white vinegar.

  • Juice from 2 lemons
  • 2-cups of white vinegar

Pour into a quart spray bottle and finish filling the bottle with water. Mix well to combine the ingredients and spray the weeds. Make sure to spray the underside of the weed leaves, too.

4. Boiling Water

Plain, simple boiling water is highly effective on weeds that grow in the cracks of sidewalks, driveways, and between patio pavers.

Simply boil water and pour it on the weeds while the water is still extremely hot. Be careful not to burn yourself.

Using an extra large tea kettle is the best way to pour the boiling water on the weeds while staying safe.

5. Baking Soda

Baking soda is an effective weed killer and is suitable for use on an area with nothing but weeds growing on it.

This is a simple way of using baking soda to control weeds in-between paver stones or in cracks in the sidewalk or driveway.

Always use caution when applying baking soda or any type of weed killer when desirable plants are nearby. Even though baking soda is readily available in most homes, it can still damage grasses and flowers that you are growing, so use with caution.

Sprinkle the baking soda generously on the weeds and, they will die. The sodium bicarbonate acts slower than the other DIY weed killers, but it will clear the soil section of weeds.

You must cover the entire weed for the baking soda to be effective. Apply the baking soda at the rate of approximately one tablespoon per plant.

Remember, baking soda is salt, so it will also raise the pH of the soil.


When and How to Apply for All Types of DIY Weed Killer Recipes

1. On a bright, sunny morning or afternoon, apply any of the above safe liquid weed killer recipes. Be sure all the dew has dried off the foliage and that rain is not in the forecast for the next 24 hours.

2. Make sure to saturate the plant. Be sure to soak the underside of the leaves and the soil at the base of the plant.

3. To prevent the spray from getting onto nearby plants, cut both ends out of a tin can or milk carton and place them over the weed plant before spraying.

4. Store all remaining mixtures in a cool location and use them as needed. Label spray bottle.

5. If using the dry baking soda, sprinkle on the weeds when the leaves are damp but when there is no rain in the forecast.

4. Store all remaining mixtures in a cool location and use as needed. Label spray bottle.
