An Easy Homemade Weed Killer with No Harsh Chemicals

Caring for a yard and garden can be extremely satisfying—but it can also be a lot of work. If you have sidewalks, garden pathways, or other areas that are prone to pesky little weeds, this post is for you! Say goodbye to harsh, smelly, and toxic weed sprays: this one uses ordinary kitchen ingredients and is perfectly safe to use around children and pets. You don’t have to worry about fumes, either, or about polluting the ground or water supply!

The easiest way to use homemade weed killer is to put it in a large spray bottle or even a pump sprayer. From there, you can use it to spritz any annoying weeds that are popping up in the wrong place. However, keep in mind that it’s non-selective, meaning that it will kill flowers and veggies as well as weeds! So while it’s great for keeping the grasses out of your gravel walkway, it’s not a good candidate for killing weeds in your flower border, herb garden, or anywhere else with plants you want to keep.

What You’ll Need

This 3-ingredient homemade weed killer is very easy to make and use. The best part is that it truly works! And there are no harsh chemicals or toxic ingredients. All you need are three simple items:

  • Vinegar: For one batch of weed killer, you’ll need a gallon container of white vinegar.
  • Dish Soap: Any ordinary dish detergent (not dishwasher detergent or tabs) will do.
  • Salt: You can use regular table salt, or use Epsom salt. Either one will work!
The ingredients (vinegar, dish soap, salt) for natural weed killer.

How to Make Homemade Weed Killer

You can mix this weed killer directly in the spray bottle you plan to use it in, or just in a large glass or plastic container with a lid.

Dissolve the Salt in the Vinegar. First, pour the salt into your container, and add the vinegar. Shake the salt and vinegar together. It’s best to let this mixture sit for an hour or so, to let the salt completely dissolve.

Add the Dish Soap. Next, add the dish soap. Shake again, gently. Once all the ingredients are combined, you are ready to spray your weeds!

Does Natural Weed Killer Really Work?

It really does! Essentially, this homemade weed killer is excellent at drying up the weeds’ foliage. Both vinegar and salt go to work drying up the moisture in the weeds, while the dish soap acts as a surfactant, preventing the plants’ natural barriers from repelling the weed killer.

For best results, make sure to use this natural weed killer on a sunny day. Sun helps dry out the weeds, while a rainy or damp day would decrease the weed killer’s effectiveness.

After you spray the weeds, it may take up to 24 hours for them to completely die. Bigger weeds may need multiple treatments.

Bonus Tip: Cornmeal Gluten for Weed Prevention!

According to Friendly Organics Canada, there appears to be good evidence showing that cornmeal gluten works well as a weed preventer. So while it won’t kill existing weeds, it may be a great, natural way to prevent weeds from sprouting up, without the threat of toxic chemicals!

    Will it kill sego palms

  2. Mrs. Hess says:

    How long do you have to wait after the weeds have died to sow grass seed??

  3. sonya norton says:

    This works, BUT: it depends what you want to do+. Are you trying to knock down a stand of weeds or grass so that you can q+prepare a raised bed over it? Then, yes, Epsom salt is ok, because magnesium is a stimulant for root growth – and that’s what Epsom salt is, primarily. If, however er, you want to insure that nothing grows in that location ever again, use table salt. Salt blocks soil from holding moisture. Vinegar is adequate all by itself if you plan to plant something else in that location eventually. However, agricultural vinegar, or at least a 10% solution ( agricultural vinegar at 50% ) is more effective then kitchen vinegar.

    Will it kill dandelions?

    1. David Duane Schultz says:

      You don’t want to kill dandelions as bees need them to survive.

      1. Ann Onnen says:

        Yes, please do not kill dandelions! They are among the first “flowers” of the season for bees and other polliators and make a huge differnce in keeping bees alive. Dandelions don’t last that long. Bees/Honey Bees however are so necessary to humans surviving!

  5. Stephanie says:

    Will this work on Sumac, poison ivy and poison oak too?

    1. Missy says:

      Yes it does. But the vines still contain Urushiol and need removed. It works good. I see no new growth and can tell the vines are dead. But sadly still poison ivy rash from not being careful because I thought I was ok after dozens of exposures. Lesson learned. Use trash bags and gloves. Make sure to layer up and pitch clothes you wear or bleach. 

  6. Linda says:

    Can this mixture be used on/or around bricks, without eating up the bricks?

    1. Wendy parikh says:

      If this is sprayed in a vegetatable garden area, will plants grow in that garden? What would the time frame be for planting in a sprayed area?

  7. Teresa Allen says:

    Can you replant where you have sprayed? I worry about 5he salt residue killing new plants.

  8. Robin says:

  9. Mary Jane Hartz says:

  10. B K. says:

    This does not work unless you are using agricultural grade vinegar. It is however an awesome cleaner for tubs and tile.

    1. Janet Newburg says:

      Yes, you are correct. I ordered the stronger vinegar on line and used it.

    2. Florence Johnson says:

      I used the distelled white vinegar bought from the grocery store and it work Great!

    3. Betty Jo Schreck says:

      I also used the white vinegar from store and it killed all my weeds.

    4. Susan says:

      5 stars
      Even with regular vinegar it will kill grass really good but the weeds need the agricultural grade vinegar to work best. I do this all the time and it Always kills the grass.
