Hands Down the Best Way to Kill Weeds and It’s Not Roundup

In 1970, John Franz, a chemist for Monsanto, discovered that the chemical glyphosate is a potent herbicide that kills just about every kind of plant material imaginable. In no time, the company gave its miracle weed killer the brand name Roundup.

Farmers, especially, went wild for Roundup. Just one problem: It was nearly impossible to kill the weeds without also killing their crops. So Monsanto sent its chemists back to work to develop glyphosate-resistant, or “Roundup ready crops” that have had their DNA altered (genetically modified or GMO) to allow them to be immune to glyphosate. Now farmers could spray with abandon and not worry about their crops.

To say that glyphosate, Roundup, and GMO foods have become a bit controversial would be, to put it mildly. There are some who say that glyphosate causes cancer in animals, and most likely humans, too. They insist that the side effects of long-term GMO food consumption are producing serious health risks for all living things. Despite all of this controversy and outcry about issues surrounding Roundup and GMO crops, so far the Environmental Protection Agency (EPA) has not forced Roundup off the market. It’s a hot-button issue, that’s for sure.

DON’T MISS:  7 Ways to Wage War Against Mosquitoes—and Win!

There is one provable and very compelling reason to not buy Roundup: It’s too expensive! Even if it were proven beyond a shadow of a doubt that Roundup is safe as water, I still wouldn’t shell out the high price for the stuff. I kill weeds like crazy with kitchen pantry items that are really cheap and non-toxic: white vinegar, ordinary table salt, and dishwashing liquid.

Before and after photos best way to kill weeds not Roundup

First I will give you the ingredients, followed by two Weed Killer recipes using them:

White vinegar

Ordinary distilled white vinegar with 5% acidity is cheap and works great. If you can find a higher acidity even up to 20%, it is going to work faster, but the end results will be the same.

Table salt

Use the cheapest kind of salt you can find in the supermarket—NOT sea salt, rock salt, Epsom salts (Epsom salt, chemically, is not even close to table salt, trust me on that) or anything fancy. Just cheap iodized or un-iodized generic salt also known as sodium chloride (NaCl).

Dishwashing liquid

You will be using only a few drops, so the brand doesn’t matter. The purpose of the soap is to break the surface tension of the vinegar so it sticks to the weeds, forcing them to absorb it more readily.

Weed Killer for Areas to be Replanted


If you have weeds in areas you want to replant, do this: Fill an ordinary garden sprayer with white vinegar and add about one teaspoon liquid dishwashing soap like blue Dawn or Meyer’s Clean Day. Apply sprayer top and follow the instructions on the sprayer to get it ready to spray. That’s it. Seriously, it is that simple.

Pick a hot, dry day to spray weeds until saturated, and they will wilt and shrivel up within hours so be careful to not spray anything you want to live. However, do not worry about the vinegar killing anything below the soil. Because vinegar will not harm the soil, you can safely replant the area once the weeds have died.

SURPRISING: Dinner-in-a-Box is Not What I Thought

Weed Killer for Areas Never to Grow Again

To kill all vegetation in walkways, driveways and other areas where you don’t want any living thing to grow again, mix two cups ordinary table salt with one gallon of white vinegar. Do this in a container that is larger than one-gallon capacity so you have room for the salt. Apply the lid and shake to dissolve the salt. Salt dissolves more quickly in vinegar than in water, but it takes a bit of doing. It may not completely dissolve, but that’s okay.

Add 1 teaspoon of liquid dishwashing soap (this is to break the surface tension of the mixture so it will stick to the plant material you’ll be killing). Pour into an ordinary garden sprayer. Apply to weeds or grass on a dry, sunny day to areas you don’t want to see vegetation of any kind in the future.

The presence of salt in this recipe is what will eventually bring permanence to your weed killing. The salt will penetrate and leach into the soil. It may take several applications, but in time the presence of salt will “sterilize” the soil in this area so that nothing will grow there. Plan well before you go this permanent route.

These homemade weed killer recipes are not only cheap, but both are also completely non-toxic to humans and animals. In fact, except for the soap (not toxic, but not very tasty), you could have fun with the family tonight when you tell them you made the salad vinaigrette using 3 parts olive oil to 1 part weed killer!

    Thanks for explaining that the soap is just to break the surface tension on the plants because I like to know how things work. I have tons of weeds in my yard. It’s insane how tall they’ve gotten. After weed whacking them, I want a way to make sure they don’t come back. https://armedforcepest.com/calistoga

  2. Steve A says:

    I know a 22 year old boy who took a job on a farm and he was the “Roundup” guy. After a couple of years being the roundup sprayer he is in the hospital dying of cancer. I’ll take the vinegar, salt and dish soap over cancer any day.

  3. Michael Briansky says:

    Before coming across the information given here, I used Roundup to keep my driveway and walkway clear of plants. Let me say that I will never use it again because of the high costs and potential harm to my health. I can now get rid of weeds in a non-toxic and cheap way by only using house ingredients.


    • Andre Wasserman says:

      I used vinegar & dish wash detergent too and it appeared to work just fine.
      I read somewhere it can be diluted, so mixed mine +-50% with water. Sure, the weeds browned & appeared dead, BUT not all died. The bigger, fatter broadleaves just looked the same. Then light rain came & approx. 60% of the weeds are forming new leaves and pushing up new flowers again (dandelions). A friend recommended pool acid: at even way less than 10% dilution, he says it’s quite effective.

      • LGJ says:

        You don’t think the reason your use of the homemade weed killer might have been because you did – not – follow – the – recipe??? By diluting it with 50% water, of course it doesn’t work! To blame the original ‘recipe’ when you didn’t use the original ‘recipe’ is ludicrous!

    So grateful that you shared 🙂

  5. Beth says:

    I would like to kill all the vegetation in my garden area, put a top cover o er it and cover that with bark. My question is, how many times should I have to spray before I can cover and how will my tree fare, which is in the center of the small plot?

  6. Skylar Williams says:

    Thank you for your tip to use white vinegar, table salt, and dishwashing soap to kill weeds. Now that it is fall, it is time to do some weed control. I’ve noticed that I have a lot of weeds growing in my garden and my lawn and I need to get them sprayed. In my case, I’ll need a professional to come and take care of that job for me. https://forevergreenlawnandpest.com/services/lawn-services/

  7. Lynn says:

    Thank you for sharing, this really works! I live in AZ and weeds seem to be extra tough here – actually Roundup does nothing to kill some types of weeds we have. Yesterday I sprayed a solution of Heinz Cleaning Vinegar with Dawn detergent. This morning when I checked, ALL the weeds I sprayed were dead, even the extra tough ones.

  8. TactlessMonkey says:

    A lot of commenters concerned about the salt. Did you guys even bother to ready the article?? Omit the salt and use the vinegar and soap only in areas where future planting is desired. Driveways, cracks and seams along the curb, etc salt is a great alternative to not worrying about it in the future.

  9. Deg says:

    If I use salt in the recipe would that seep over to my plants that are two feet away? That’s my concern. I don’t know where that salt will go.

  10. Jason says:

    I tried the same method of vinegar, table salt and Dove soap. I have a long, badly heaved interlocking driveway so I don’t find the pump sprayers very effective. Even if you hit every nook and cranny the amount of spray is not that much. So I tried a paint roller. I sopped up a good amount and just rolled it on. Way faster and highly effective

    • DC says:

      Thanks for your method and the telling of your results. I was planning to use a paintbrush in areas where I do not want vegetation to grow ever. Your idea of the roller on the driveway is even a greater solution!!! .

  11. gecota says:

    I have flowers and ground cover next to the weedy driveway, if I use the salt solution on the drive will it leach to the ground beside it and kill my iris, etc as well?

  12. Rod says:

    Use the vinegar solution if you want, but if you’re really a “cheapskate” (and not hung up on all the scare stories about Roundup) then use glyphosate purchased at a farm supply outlet. A 2 1/2 gallon jug of glyphosate (the active ingredient in Roundup) mixed at a rate of 2 oz per gallon of water will make 160 gallons of weed killer for about $40. That’s 25 cents a gallon and it kills all the way down including the roots.

    Seeds will sprout eventually and most areas will need regular respraying, however, like with the vinegar without salt added. It won’t sterilize the soil like the salt does.

    • Alan says:

      Certainly white vinegar isn’t cheap at around $2/gallon. How well does it work? Glyphosate applied at the proper rate is cheap and works with no build up..

  16. Penny Cashen says:

    if I use the salt method, how far must I stay away from an area that I do want plants to grow in. I want to spray around the concreat in my yard but not kill the plants that grow further in the back of the yard.

  17. Ed says:

    Another great alternative is a propane torch. They’ll run you $20-$30 at places like Harbor Freight or Northern Tool. Make sure you get the kind with a hose that hooks up to a propane tank like you use on a grill. The ones that use the small camp stove canisters are junk. It kills everything without ruining the ground and yard work has never been so much fun. I’ve burned a fence line clear or ivy and other weeds in the rain with it.

  18. toohip says:

    This is popular “internets BS.” Science, not folklore or social media, is the way to address issues of chemicals and treatments regarding our living plants. Virtually all state and county ag. extenstions point out that the “vinegar and epsom salts (dish soap) magic recipe does not work, and can be also dangerous and the unproven allegations against glysophate (Roundup). The “internets” and it’s social media are FILLED with home remedies on virtually everything from cleaning your home to quick fixes in the home or auto to garden herbicides. This one is one of the most popular, and while there is a marginal measure of success, it’s no where near the effectiveness of herbicides and glysophate. 5% vinegar won’t do the job, and moving to dangerous 20% “horticulture level” vinegar is so dangerous, protective gear is required, not recommended. Added to this is this will kill the above ground plant, but it won’t kill the roots as glysophate does, and the weed will eventually return. To your research, and don’t go to social media or sites like this. Use government or actual education (university) sites that use science, not folklore.

    • jeb says:

      UNPROVEN ALLEGATIONS? Last I checked, the chemical companies were shelling out BILLIONS of dollars in claims. With a “B”. I’m guessing that was due to proof, not a good gesture.

    • Tech says:

      Roundup causes cancer. It is airborne in high quantities all year long due to incessant over-spraying by cheap businesses and municiplaities. You can fee your mouth and tongue burn/tingle when its inhaled and you know someone is spraying somewhere. You can wake up and spit blood if it’s really nearby. It’s a cash cow for chem companies who don’t care about people’s kidneys or life expectancy. Salt works great for areas you want to kill weeds and a spade and a bucket works well for gardens. Phosphonates (Roundup) don’t break down the C-P bond easy which is why they are so toxic. The body has to flush it out via the kidneys. and Roundup acts as an antibiotic killing good mouth & gut bacteria because gram positive bacteria absorb so much of it.

      All the astroturfers trying to dissuade people from natural and safe methods of weed control have a spot reserved for them in one of the rings of hell.

    I have been using table salt, white vinegar and dawn dish soap. They work wonders on killing my weeds. The problem is that the sprayers I am using seem to get all gunked up with the salt. They stop spraying after like one bottle full of the mixture. Any advice on what type of sprayers to use? I’m tired of buying cheap sprayers.

    • Mary Hunt says:

      Sorry Mack … yes 5% acidity vinegar will kill vegetation; 30% will just do it faster. And you’re right on salt as well. That’s why salt is only in the recipe for areas you want nothing to ever grow again. Note: It takes multiple applications of salt for that to happen. Thanks for stopping by!

  26. KEN says:

    I spray my tomato plants with a mixture of water and dawn dishwashing soap it didnt kill anything around it or my plants so I dont think this will kill weeds or grass

    • Mary Hunt says:

      Hi Ken! It’s the vinegar + salt that does the job on weeds. The dishwashing liquid is a surfactant, which means it breaks the surface tension of the liquid, allowing it to stick to the plant/leaves. You’re right. Soap won’t kill tomatoes! I wouldn’t suggest you perform this same test with vinegar and salt, however!

  27. Timothy Hossfeld says:

        I remember DDT. I inspected the basement of a 100 year old house in 1998 and there were no insects! At all! We found that DDT had been applied (don’t know when) and it was still at work! However, Roundup goes inert in the soil 30 minutes after application. That’s why the EPA allows it to be be sold anywhere. Fortunately, it is “idiot proof”.

    I read this article by Robert Pavlis who says NaCl doesn’t break down in the soil, whereas glyphosate does. He sounds like a Monsanto hack but I’d appreciate if anyone could verify or refute any of this. I’m just a simple caveman trying to kill the weeds on my patio without ruining the planet. http://www.gardenmyths.com/homemade-weed-killer-roundup-vs-vinegar-vs-salt/

      Pavlis is one of the most impressive gardeners I have ever read. He is intelligent, experienced, does his research *and* his own experiments, and explains everything in practical detail. In contrast to 90% of such bloggers. “Mosanto hack??” You have a serious perception problem.

  29. SuperGreen says:

    Tried the vinegar/soap and it was a complete fail. Maybe some minor wilting but nothing was even close to being killed, nothing. A whole gallon of 5% acetic acid in my pressurized sprayer – my patio smelled like a vinegar factory! I’ll try the salt now I guess. Anyone else failing?

    • James says:

      Yeah, this failed once before for me as well. I made a super concentrated mix in a 5 gallon bucket for my home in Colorado and added to much salt. It killed my entire lawn at that time and the yard filled up with weeds the next spring. I have to try it in NM hence why I asked about the tall Fescue issue. Be careful about the salt! I’m beginning to think resodding may be the cheaper overall solution.

  30. James says:

    Will this method work on Tall Fescue in my yard? I just moved into a new house and noticed my Bermuda Grass garden beginning to have patches of Fescue. I verified that it is indeed Tall Fescue and not Crabgrass by research and a calling a local gardener.

    • Ri C says:

      If you mow your lawn shorter than two inches, the fescue will be at a big disadvantage and the bermuda should overwhelm it in time. If you just want to burn it down, I would suggest using a roofing torch to cook the fescue and then reseed with a good bermuda blend.

  31. timbo says:

    I can’t imagine that two cups of salt sprayed on any area would be enough to keep the rain from leaching it away in a single season in a rainy region like Western Oregon/Washington. This must be a recipe for the Central Valley of California.

    Actually, by far the best is something you shouldn’t use anymore . . . But I used to live out in the country where they used old motor oil from the county trucks on dirt roads.

  34. robert shaw says:

    I agree with the people who advise against using common table salt (sodium chloride) as a weed killer. From personal experience, it killed the weeds in my sidewalk cracks, but it also adversely affected any of the plants which had roots in the area, including several large specimen trees. It seemed to have been a very poor decision, and it did, in my case, leave the otherwise fertile soil unusable. Just stating my experience; people who like talking snarky-tough about tree-huggers can save their comments for someone who cares.
    I also agree with the people who suggest that a lot can be gained (and a lot of work avoided) by reassessing what you regard as a weed or not. It’s especially puzzling when people “pull a weed”, even if they don’t know what it is. It might be more interesting or valuable than the plant you’re trying to grow. Or it might attract pollinators or parasitic wasps to benefit the other plants. Best (and more thoughtful) to identify the plant first, before killing it.

    So far, Roundup has been my only effective solution for bindweed and whitetops. I do not wish to saturate the soil with salt, making all growth impossible forever.

    • Sickofthis says:

    • Emily27 says:

      The whole point of using natural substances is to avoid products like Roundup to begin with. The toxicity level alone should scare you.

  38. Douglass Stevenson says:

    Seven points on this discussion.

    (1) Salt is not exclusively sodium chloride. There are many salts. A salt is the reaction product of an acid with a base. Sodium chloride (table salt) is the product of hydrochloric acid and sodium hydroxide. Epsom salt (magnesium sulfate, MgSO4) is a true salt, the product of sulfuric acid and magnesium hydroxide.

    (2) Sodium chloride (NaCl) does not poison the soil. All soils have varying quantities of sodium in them. Sodium does cause soils to become impervious to water by locking onto clay micelles and displacing calcium (Ca), causing the soil to become like concrete. However, the condition is not permanent unless you keep adding sodium every year. Even then you can cause a sodic soil to recover by adding gypsum (calcium sulfate, CaSO4), another salt, or sulfuric acid (H2SO4), which reacts with soil calcium to create gypsum, which displaces sodium. The sodium is released, becomes soluble and leaches away with either irrigation water or rain.

    (3) When a salt is mixed with vinegar (acetic acid, CH3COOH), it dissociates into cations and anions. In the acid solution in vinegar (approx 5% to 6 % acetic acid) its reaction with plant tissues is a combination of an acid burn and a salt burn. The acid disrupts cell membranes. The salt causes cells to lose water. The combination is a rapid burn and dry down of treated foliage. You can use a lot of different salts to get this effect. The alkali metal salts (lithium [Li], sodium [Na], potassium [K], rubidium [Rb], cesium [Cs]) are the most toxic, followed by the alkaline earth metals (beryllium [Be], magnesium [Mg], calcium [Ca], strontium [Sr], barium [Ba]). Their salts increase in toxicity with molecular weight, i.e. sodium chloride (NaCl) is more toxic to plants than lithium chloride (LiCl), and potassium chloride (KCl) is more toxic than sodium chloride. Furthermore, their halide salts, particularly with fluorine (F) or chlorine (Cl) are the most toxic. Sulfate salts (SO4) are less toxic.

    (4) Finally, if you want a really hot “salt & vinegar” weed killer, try vinegar and potassium chloride. Potassium chloride is found in “Light Table Salt” (not salt substitute) and is more expensive than ordinary table salt. However, fertilizer grade potassium chloride (murate of potash, 0-0-60 fertilizer) is cheaper than table salt. It is not as pure as table salt because there are insoluble components. But if you mix the murate of potash (KCl) with vinegar at the rate of 1 or 2 cups to a gallon of vinegar, you will get a very hot weed killer.

    (5) With 0-0-60 murate of potash, there is a mineral component that is not readily soluble in water or even dilute acetic acid (vinegar). Therefore, when you mix the murate of potash with the vinegar stir vigorously until most of it is dissolved. Let is stand until the insoluble mineral component settles out. Then transfer the clear solution to your sprayer. Then add liquid detergent, and do not stir to avoid foaming.

    (6) The effect on soil is negligible because unlike sodium, potassium is more reactive and does not cause the soil to become alkaline. Potassium is a plant nutrient, and once in the soil, it provides additional nutrients. If you check your garden fertilizer label, you will find that it contains potash (potassium) usually in the form of murate of potash (potassium chloride, KCl). Potassium, like nitrogen in fertilizer is quite water soluble and will readily leach out of the root zone of plants. So it must be replaced periodically.

    (7) My experience with potassium chloride fertilizer showed me how toxic it can be. About 35 years ago, I was an agricultural consultant with a large, multi-state farmers cooperative association. An orchard owner in Washington, Utah, asked for a fertilizer recommendation after a soil test showed a potassium deficiency. I recommended about a quarter pound per tree applied in the drip zone of the trees. The “drip zone” of a tree is the area under the tree just where the branches of a tree end. It is the area where the maximum number of feeder roots exist closest to the soil surface.

    The orchard owner, however, was a city guy who had never farmed anything before. He had moved to the rural area of Washington County to become a gentleman farmer, while he continued to commute by air to his office in Los Angeles. He had no idea where a tree’s drip zone was, so he placed the murate of potash against the trunks of his trees. A few months later, he called to say that his trees were all dead and had been killed by the fertilizer. When I investigated, I found that the murate of potash, still in crystalline form, in direct contact with the tree trunks. It had destroyed the bark, cambium and water conductive outer xylem of the trees. I explained where the drip zone was and that his lack of understanding had caused him to kill his own trees. We saved most of them by bridge grafting, and about half survived. But this demonstrated how phytotoxic concentrated potassium chloride is.

    That was the idea. Kill everything so that nothing will come back. I want to clear a patch of land to put a greenhouse on it. Weeds are now gone, but will come back. I want everything dead. Extinct. Gone. Never to return…

  42. Crystal Allen says:

    According to my calculations, comparing cost of a gallon of white vinegar vs what it would cost for 4 tablespoons of RoundUp per gallon, RoundUp is CHEAPER. That being said, I refuse to use RoundUp because of what I perceive as dangers, to myself and family, future food crops, etc. And I just don’t like Monsanto.

      • Crystal Allen says:

        We used to use RoundUp from time to time (before we knew better), and mixed it 3 oz per gallon. Walmart sells 64 oz of concentrate for 38.92. That makes it $1.82 / gal. For stubborn weeds we mixed it closer to 6 oz per gallon, which costs $3.65 per gallon. So the vinegar is in the ballpark, between those two extremes.

        The only issue I have had with the vinegar mix is that I have to repeat the spraying often. It burns the foliage, and that does not guarantee that the root dies as well. For large areas, heavy black plastic in the hot sun works wonders!

      • Roger M says:

        It’s hard to compare the cost of Roundup with Roundup because it comes in many different concentrations. It is sold diluted ready to use (very expensive) and in different concentrations. If you buy at Wally World it will be more expensive than if you go to a farm supply store that sells to farmers.

  43. Deb Radman says:

    There is another reason to not use RoundUp. My father got Roundup on his hands in April 2015. He broke out in an all body rash which persisted until July. Then his platelets dropped to single digits. The docs did blood transfusions and finally a bone marrow test. He had what they call a “blast crisis” leukemia condition and the prognosis was that he would not survive. He was dead a month later. There are class action suits against Monsanto about several different diseases users have contracted. But there is no effort around “wrongful death.” I urge anyone using RoundUp to stop; get rid of it. It’s poison and it will kill you.

    • Paul says:

    • Ri C says:

      Roundup on your fathers hands did not cause his illness. Glyphosate does not penetrate skin well at all. It also works on a protein pathway that does not affect humans. Glyphosate is extremely safe and has never been shown to cause any ill effects even for those of us who use it every day. It is sad that your father got sick, but spreading misinformation can also cost lives. Without the use of safe herbicides like Roundup, people in other countries will starve and die of undernourishment.

      • Ann Snow says:

        Gee. You know this for sure, do you? Read my post at the top about my cat. All her doctors agreed there was no way (young, spayed) she could have gotten the cancer other than by toxic agents. How about the man’s father having small cuts or open areas in his hands as entry points? How about just the pores in his skin? And how about people in other countries? How many of them sickened and died because of Roundup? You know this too? Don’t think so.

    Thank you for telling me about Epsom salt. I have read of it being used as a soil supplement. I have seen a recipe for weed killer calling for epsom salt, but it didn’t work for us. I know that in the Bible it mentions where salt was sowed in the fields of the enemy.

    Judges 9:45 And Abimelech fought against the city all that day; and he took the city, and slew the people that was therein, and beat down the city, and sowed it with salt.

    • laststand says:

      Salt is an extremely bad idea for general use as a weed killer. It ruins soil tilth and accumulates to toxic levels because plants do not use the salt. Over time salt will render your planter beds or garden areas completely fruitless.

      I’m an all phase landscape contractor with over 30 years on the ground and over 20 years running my own business. Roundup is the best that science has to offer, the active ingredients are all used by plants. The only thing you really should concern yourself with is runoff or working near any watershed or river. I refuse to spray near these places. This irresponsible rhetoric about Roundup causing cancer, or that “you should use salt” are lies spread by organic food growers who are trying to push their vastly overpriced products. In doing so they are damaging the earth, it’s really that simple. If you’re smart, and I think that you are… then you wont use salt to kill weeds.

  47. Kathy Meadows-Goodman says:

    I’ve noticed several new ‘recipes’ online that suggest using Epsom salt instead of table salt. Please note Epsom ‘salt’ is NOT in any sense of the word actually salt. It will do nothing except possibly help the weeds revive. Epsom ‘salt’ is not true Salt; true salt is Sodium. Sodium/Salt acts as a drying agent, which is why Sodium Chloride, aka table salt kills plants. Epsom ‘salt’ is actually a pure mineral compound of magnesium and sulfate in crystal form. It looks like salt crystals so it’s labeled ‘salt’, but it has no sodium chloride. In fact Epsom salt is used as a FERTILIZER or plant booster for many plants including roses and tomatoes. The vinegar alone will do a much better job, probably, although the vinegar will only kill the parts above ground and not a root. Sodium chloride or true salt will kill the entire plant, leaves stem, & root, BUT it will also sterilize the soil and nothing else will ever grow in that spot where true salt has been put. Epsom ‘salt’ will not harm the plant nor the soil.

    • Edward Keating says:

      Actually, salt is a general term and magnesium sulfate, or Epsom salt, is a salt. A salt is any compound formed from the reaction of an acid with a base. But you are correct that it will typically aid plant growth because both magnesium and sulfur are necessary for plants to grow. Sodium chloride works well for this use because not only does the salt absorb large amounts of the water, keeping it from the plants, but the chlorine will separate from the sodium molecule and be absorbed by the roots. The resulting toxicity builds up quickly, killing the affected plants.

    • killermouse1974 says:

      to reinforce comments by edward keating…..

      epsom salt aka magnesium sulfate is, without any doubt whatsoever, a salt.

      sodium chloride aka table salt is but only one of many many many many many salts, and all are “true salt” using your term. “salt is an ionic compound that results from the neutralization reaction of an acid and a base”.

      salt can be categorised in different ways eg component ions can be inorganic or organic, and can be monatomic or polyatomic, and there are varieties of salts dissolved in water eg salts that hydrolyze to produce hydroxide ions are basic salts, whilst those that hydrolyze to produce hydronium ions are acidic salts, and neutral salts are those that are neither acid nor basic salts.

      many fertilisers used in agricultural are salts and/or derived from salts eg potassium sulphate, potassium nitrate, potassium chloride, monocalcium phosphate aka single superphosphate, monoammonium phosphate. micronutrients like molybdenum, zinc, and copper are provided as water-soluble salts. these are all salts, or as you put it “true salts”.

      salt can absorb water that would otherwise be available to the roots and effectively dehydrate them causing plant stress, which can kill the plant.

      but sodium chloride aka table salt is toxic because it is made up of sodium and chloride and both are toxic to plants when present in high concentration. sodium ions in the salt
      replace other nutrients in the soil that plants need eg potassium calcium and magnesium, so these nutrients become unavailable to the plant. roots absorb the chloride ions and transport them to the leaves, where they accumulate and interfere with chlorophyll
      production and photosynthesis.

      although i did an agricultural degree, it was a long time ago and i have forgotten a lot of what i learnt, so i had to do some reading to be able to write this response, and i might not have explained it perfectly compared to a soil and/or plant specialist, or someone willing to do more reading than i did, it is more or less accurate and based on science, rather than uninformed and inaccurate opinion.

      • Mark Mauerman says:

        Holy shiest! What an amazing science lesson! Probably learned more right here than I did in my last science class.

    • Beuna Tomalino says:

      Although Epsom salts are used as a fertilizer I have used it with vinegar and the results were very good. I wondered how Epsom salts could help but it did. So maybe there is something about the combination of the two.

  48. Robin Lillian says:

    Salt poisons the soil. It makes it barren for generations. In the past, when a conquering nation wanted to destroy a land/people, they would sow the water and soil with salt. (The Bible has examples.) Not all pollutants are new inventions.

    PLEASE stick to vinegar and dish soap, etc. Even if you never want ANYTHING to grow in that spot EVER again, what if you sell the house? What about future generations?

    Remember, we do not own the world. We merely borrow it from our children.

    This is not a criticism of anyone. Just please understand that the consequences of salting the earth last a very long time.

    • Jack Snakes says:

      Christ – what a load of drama queens. rain water will eventually leach salt out of the soil just as it leaches out everything else. Here in the UK, that would take about a week in March…

      • Sweetie says:

        It’s not “queen” anything. Salinization of soil is a huge global farming problem. Intentionally adding sodium salt to soil is stupid. In fact, it’s my opinion that sodium salt should be illegal for use as an ice melt. Calcium chloride works better (twice the number of ions per gram and effective at lower temps) and is safe for plants.

        “Soil salinization is a serious and difficult to reverse form of soil degradation. Topsoil salts can greatly reduce agricultural productivity, erode infrastructure, and impose long-term limitations on land productivity.”

      • Ann Shaffer says:

        I found the same thing. I used salt and vinegar in driveway cracks but the rainwater washed it away. Still growing weeds in the cracks..

    • fmrRhinoGib says:

      Gatorade might be the answer. In the movie, “Idiocracy”, the government ordered all farmers to irrigate their fields with it instead of water on the count that Gatorade was more nutritious, lol. Ms Lillian, while I respect your intent, I don’t think everyone is bent on sowing their entire yards with salt. What little is suggested here is far from the Biblical proportions you’re referring to.

  49. Dee says:

    I have killed weeds in my backyard that grow around my pool area, by using the salt/vinegar method. However, the soil composition has changed, and now there are ant colonies throughout the whole area. To get rid of the ants, I pour boiling water on them, but it is a large area, and not a permanent solution. Any advice?

    • Seth says:

      Hi Dee, have you tired the ‘Borax solution’ we had a problem with ants once and I tried all the ant sand, ant powder, commercial insecticides etc and the ants just kept coming back! I found the borax recipe in one my Dad’s old gardening books, so I mixed it up and used it around the ants, after a few days it works wonders. I couldn’t find the book but I did find the recipe for you on the internet: ”Mix one cup warm water with ½ cup sugar and 3 tablespoons borax. Soak it up with cotton balls and place them in shallow dishes near ant trails” I found it best to place the balls near where the ants nest. It doesn’t kill straight away as they carry it back (the solution, not the cotton ball!) to the nest. Try not to disturb or kill any ants you see as you want them to keep coming for the solution.
      I bought the Borax from the supermarket in the laundry section. Hope this works for you.

      • judeanbob says:

        Another way is to use Borax powder mixed with icing sugar in equal parts, the ants love sugar and will transport both the icing sugar and borax deep into the nest for all to enjoy. If you can’t find any Borax, use baking soda mixed with the icing sugar instead. Ants have no way to expel gas from their body generated by the baking soda once they eat it with the icing sugar. They will swell up and rupture causing death.

    I have a pile of dirt that keeps growing weeds and so far this process is taking along time, I have hit it like 3 times now and a lot of it is still green.

  51. Scott says:

    Sure fell in love with the ‘natural’ home remedy herbicide…Until I read about the toxicity of each and not to mention the permanent soil sterilization that salt does. As to price – Still not a winner. White Vinegar is between $2.50 to $3.50 a gallon, disregard the price of an oz of dishwashing liquid and skip the salt and you are going to use that straight no dilution. Eliminator (A glyphosate only weed killer is currently $34.99/gallon) in a gallon container using at the strongest recommended concentration is going to cost you just under $.70/gallon that’s bout 25% the price of just white vinegar and with white vinegar you get a top only kill of everything and with glyphosate you get a systemic kill. BOTH break down in the soil – that is unless you add salt to the ‘home remedy’ mix and then the price goes some more and you render that soil sterile for a lengthy period of time. And lest we forget, that salt will leach into the surrounding soil with affects determined by how high that concentration rises over time.
    I’m not pro-roundup or any other chemical. BUT given that the EPA still has not found a reason to ban or provide any cancer-causing connection to glyphosate. Further at least one other report gives salt and acetic acid (the active ingredient in white vinegar) a higher toxicity rating to humans than glyphosate. I have to say – I’ll save my money and stay with Roundup or other glyphosate containing products.
    One last point – in ancient times the conquering armies that wanted to infllict the most long lasting damage on their enemies – would salt their fields to prevent any crops from growing for years. Once dissolved into the soil the soil was rendered useless for crops.

  52. Tami Yeomans says:

    I have concrete blocks with pansies growing in them along the edge of our patio. If I spray the permanent killer on the lawn side of them, will it effect the pansies?

    • Scott says:

      If it leaches through the porous concrete blocks – bingo death to the pansies. I assume you are talking about the salt because it’s the permanent killer, Roundup / glyphosate break down in the soil and it’s unlikely to leach through the concrete before it breaks down.

      • john says:

        glyphosate (roundup) is banned in many countries because it is highly cancerous and causes birth defects.

    • timbo says:

      Whenever we have pasta, I use the leftover water while still hot to hit selected weeds. It works pretty well unless the plant has a really large root. Some plants need a second dose. Too bad it doesn’t go further and hit more weeds. The advantages are that you can hit a specific weed without killing wanted plants and the dissolved nutrients in the water help neighboring plants.

  54. Gehugh says:

    As an alternative to ridding your property of every possible unsightly weed: consider consuming the dandelion greens and picking the yellow flower heads before they blow out. You might want to find out what kind of ‘weeds’ you have and act accordingly. After many years of DDE (Daily Dandelion Elimination) every spring we had it with that method and made peace with the greens and just pulled the tops. Our Fiskars weed popper was great then. We have thistle, spotted knapweed, oxeye daisy and several other noxious and invasive weeds that we work on eliminating every year. Hand pulling is the most successful we’ve found.
    There is a website, urbanfoodgarden.org, that may be of interest to those who don’t have to live with manicured lawns.

    • timbo says:

      I don’t think most gardeners who would use this method are worried about every possible unsightly weed. I would like to see it used on the weeds that have invaded you yard that are on the state’s noxious weed list, e.g. old man beard clematis, english ivy, etc. We are after lots of other weeds as well (cat’s ear, potato weed, and lots of others that overtake the vegetable garden.
      Our lawn has several non-grass plants. I love the yarrow; it looks a lot like grass and the occasional white flower is attractive.

  55. Terrie Lewis says:

    We tried this concoction this Spring on our front yard. We used Epsom salt instead of table salt from a recipe I found on Facebook. We sprayed it on dandelions in the front yard and it killed the leaves and the grass around the plant. However the dandelions quickly went to seed and the seeds blew away. I don’t recommend this method.

    • Sue in MN says:

      This is not an appropriate, research-based solution! You won’t see this recommended by trained personnel – it is not an ecologically sound sustainable gardening practice. (The University Extension Service trained Master Gardeners around the country are not paid or supported in any way by the chemical companies.) Keep in mind that just because something is “natural” or edible by humans that it is harmless. (For example, chocolate is great for humans, but a couple of ounces can kill your dog.) You are altering the chemical makeup of the soil with vinegar & salt. Vinegar must be used repeatedly to be effective (doesn’t kill the roots outright.) So you re adding acid to your soil, upsetting the natural balance, and perhaps killing or stunting beneficial bugs and bacteria that live there. Salt, as noted above, is a KILLER. In South Texas, the ground water already contains too much dissolved salt from fertilizers and salt water infiltration. This limits its use to a few salt-tolerant crops. If you live up North, look at what winter road salt does to the ditches & boulevards – only salt-tolerant plants will grow there, and many of those are weeds. Don’t assume because you don’t want anything to grow there, that the next tenant or homeowner will feel the same way.
      So, before you embrace this as a weed control, look at the full ramifications. And maybe, just maybe, spend some time pulling those weeds – it’s great exercise.

        Most everything Kathy said here is true except for the statement that Epsom salt is not a true salt. Here is the definition of a ‘salt’.
        “any chemical compound formed from the reaction of an acid with a base, with all or part of the hydrogen of the acid replaced by a metal or other cation.” Magnesium sulfate is a salt; just not the kind that is effective at killing weeds.

    Happy Thursday!!!
    I have been singing the praises of the formula since March 3rd of this year & telling all of my friends!!! I finally got in my backyard to tackle the weeds growing in the alley alongside my fence. My husband doesn’t like for me to go into the alley, so I used the formula from my side of the fence. All of those weeds died & are still gone!!! The city if LA is extremely lousy on taking care of the alleys. I plan on giving the city councilman in my area the formula so that whatever city dept handles alleys in the city can use this formula to control the weed growth. My mind tells me this attempt will be futile, but I am going to do this anyway. I will continue to use this formula & tell people about it. I have a lot more to do my the backyard, but nothing pleases me more than to do this process myself. I also take time to dig up the roots of weeds then apply the solution. That has been effective for me. My husband still is NOT a believer in this process although he has seen spectacular results! I believe what I believe! N- joy HIS day!!

  57. Patricia says:

    In Europe they have used salt to kill grass in the sidewalks. I remember my mother pouring salt in all the cracks where grass was growing. When the ground was wet we used to pull up the weeds and then put salt down. Worked every time.

    • Honey says:

      Not a good idea- It will destroy the concrete.
      Salt is a mild acid and lowers the pH in the concrete. The acidic reaction attacks
      the concrete paste and aggregate, weakening the structure and strength of the
      concrete. It also increases the pore size, allowing additional water and chemicals
      into the concrete, which can exacerbate freeze/thaw cycle damage.

      • BG Davis says:

        Back to Chemistry 101A. Salt is not acidic.
        Table salt, which is sodium chloride (NaCl), is not an acid nor a base, but is a salt, as it is formed by the replacement of the H+ ion in Hydrochloric acid by a sodium ion.
        The reason that salt damages concrete is that it is hygroscopic (it attracts and retains moisture). The excess moisture, accumulating wherever the salt solution penetrated, swells and cracks the concrete over time.

  58. Lotus530 says:

    I’m in SE Texas. I’ve never found household vinegar to be effective in killing weeds! But I’ve sworn off Roundup. The higher percentage agricultural type vinegar seems to work….it’s an ongoing battle….had a Chinese Tallow tree removed but not the stump. It’s grown back over 6 feet now. /sigh/

      A cottonwood tree that was cut down continued to grow back in spite of spraying with various poisons, cutting again and again, and burning.

She put some inexpensive wire fencing around the trunk and filled it with leaves plus some vegetable and fruit peelings. The trunk began to decompose and never grew back again.

      • Welshdog says:

        Using gasoline/diesel is one of the worst possible things you could use as a herbicide. I know it is standard practice in many places and is even recommended by agricultural “experts”, but come on! You are pouring refined hydrocarbon oils, napthalene, toluene and alkylbenzenes onto your soil. Not to mention that gasoline has benzene in it which is utterly carcinogenic. Diesel is very persistent in the soil and can also move into the water table. I am not a huge fan of glyphosphate, but please use it and not gasolene/diesel.

        Oh and one more thing, don’t ever use salt as a herbicide. That is just as wrong headed as using hydrocarbons.

  60. JP says:

    Research online brings up what most internet advice about using vinegar on weeds fails to say: “acetic acid in the vinegar works to kill the leaves on the plant but not the root”. So repeated applications are necessary if using vinegar. It’s not a once-and-done thing.

      • Dwight Johnson says:

        The article mentions that it takes several applications for the salt to penetrate into the soil. That should kill the roots.

        If you buy the vinegar at higher percentages in a non-grocery store you can have the equivalent savings by deleting it to 5%. It most likely is also less expensive to start with.

      • Roger M says:

        I buy the concentrate at a local farm store in 2 1/2 gal containers. I mix it 1 oz to the gal of water. It kills most weeds and makes all of them sick. Some weeds have a resistance and need to be sprayed a second time. Weeds will come back from seed so once and done doesn’t work for any herbicide. Using a preemergent, like Preem, will help but it also needs to be repeated

      • Charles Jones says:

        I believe Roundup works good but what is used to kill the weeds is like high dose of fertilizer so if you don’t keep using it weeds grow back more than when you first sprayed…Just like spraying for mosquito poison kills the weak and leaving the strong to breed… There natural ways to take care of all just need to do your homework

      • b53 says:

        Roger, check the cancer stats in your area. Yes, “everyone” uses it, but should they? If everyone was using heroin, would you too?

      • Sunny says:

        yes and that chemical goes right into your ground water and into the drinking water. Round-up is a toxic soup of poison for people and the environment.Stuff is just bad. stop using it.

      • Steve Puett says:

        Just sharing information, Roundup goes inert in the ground 30 minutes after contact. The amounts that are applied to plants are harmless to animal and humans. It has to be a much greater dose (like drinking concentrate out of the bottle) to be toxic. Right with you on deterring ground water pollution, I’ve experienced the effect of bad well water. Roundup is not a source to worry about. Think about it: it’s available to ANYONE. Therefore, must not be much of a worry, as far as the EPA is concerned.

      • Jer says:

        That’s exactly opposite of what I read. The article I read said it never degraded. Please link your source.

      • Chet wingo says:

        Every little bit is extremely toxic dont let them or anyone tell you any diffrent why do you think 1 million dogs a yr get cancer
        And so many people have cancer..???
        HELLO CHEMICALS!!! everyone needs to stay away from pesticides and herbicides.

      • Peajay says:

        Roundup does not “Go inert” in 30 minutes. It is detectable in the milk of most mother’s in the US. It is BANNED in the EU and many other countries. Industry owns the EPA and Congress.

      • American Me says:

        It’s now being banned in parts of the US – Los Angeles County has done it and forced all stores to remove it from their shelves. The stuff is poison, causes cancer and digestive damages. The 2nd one is how it kills bees.

      • Sterling Hill Erdei says:

        At 0.01 PPB it causes disruption to the endocrine system and has been proven. I went with a group of scientists and advocates to DC in June of 2016. We have proven time and time again it is not healthy at all. Even at 0.01 PPB it is not healthy. It is contaminated in everything now. Air, water, soil, clothing,medication, vaccines, supplements and food. We must stop using it. BTW, children with autism and people with autoimmune disease always have unacceptable levels of n phosphonomethyl glyicne/Roundup (a synthetic glycine that replaces your amino acid glycine) in their systems when tested. I encourage you before using it again read all of this research and then go into what we showed to the EPA and what we presented in our Congressional Briefing at this link. https://people.csail.mit.edu/seneff/

        Usually, when someone promotes Roundup it’s a sponsored post, I’ve seen very convincing posts/videos/lectures claiming Roundup as safe, convincing enough that you would almost believe them and purchase the product.To have an attitude that is available to everyone and therefore safe is completely wrong.
        I once took a job in a factory where the welders were having a problem with the steel arching due to its manufacturing process which left oils and other lubricants on the steel, so they got a general labor girl to dip the steel (once it was cut to length) in vats(totes) to clean the oils off. She was reaching in past her elbows to retrieve the pieces. I was out in the back lot one day and asked her what she was doing and told me she was dipping the steel in acetone to remove the oils. I said to her you can’t put your arms in there without protection, and her answer and attitude was ooh its fine it’s been on the market for years, its nail polish remover, to which I told her they are trying to remove it from the market it’s bad for you and get absorbed thru your skin, well it didn’t matter to her one bit she already knew all the facts, and to her nail polish is safe.
        to top that off, after that project was done the tote sat out in the back lot just sitting there, and guess what during break time that’s where employees took their break, drinking sodas and smoking cigarettes, I noticed and said do you know what in that tote, and explained it to them, and not one person was concerned about the flammability of the Acetone. the entire workforce was dumb as rocks!
        I had enough, (oh if only OSHA knew what was going on at this place) I only stayed 6 weeks and quit.

        I have been using the vinegar trick 3 summers in a row… nothing, doesn’t work! weeds grow up to 3 feet tall still. Had a pool on the land for 7 years, took it down, weeds grew back in less than a year. short of using a back hoe and digging deeper what other tricks are there?

      • Nikki deFoster says:

        Use cardboard or black plastic over the area- blocking the sun will kill the weeds- it’s a bit unsightly but it works. You can even use stones or pavers over the top to camouflage the barrier- it needs to sit long enough to kill the root systems completely. Vinegar method will not penetrate the roots- only new growth. If you want grass to grow in that area be very careful about using salt- salt will make the land essentially barren- kills both undesired and desired plants. Honestly, if you hand pull the large weeds or use a weed removing tool- it will be the most effective method if your root systems are that strong. Any major hardware store should have the “shotgun” style which is very easy to use and kind of fun.

      • Zotsalot says:

        Hi Ron: you actually have to add salt to the vinegar to make it work. I tried plain vinegar too and it didn’t work for me. Next time I did it with the salt in the vinegar. That is supposedly supposed to kill everything with a residual effect. The first year I did it, yes it was residual. Next year it was not. But it still killed everything. 1 gal white vinegar, 2 cups of salt and 1 tsp of dishwashing liquid.

      • Sam B says:

        I bet you could make this mix for less than $1 per gallon too if you bought the ingredients in bulk instead of 1 gallon at a time. I mean.. Come on. Use some common sense. You’re comparing the price of buying Roundup in bulk to buying the ingredients for this mix 1 gallon at a time.

      • Roger M says:

        Go on amazon and price 20% vinegar. You can’t compare by price. For a small yard/sidewalk vinegar is fine but I need about 60 gal of herbicide for one round of spraying and usually to it at least twice. My house is surrounded by corn grown for silage to feed dairy cows and they use roundup ready seed and spray with roundup. I’m not sure where the milk goes if it’s milk, butter, ice cream or cheese. I guess we are all going to die.

      • Desiree Moody says:

        Can I use the vinegar solution to control both crabgrass and weeds growing in fescue? If not what does work without harming the good grass?

      • Zach Gittings says:

        Typically what people think of as crabgrass is actually a thick bladed fescue. The answer is that you have to dig it up. Leave the other grass longer. People generally cut fescue too short. Leave it at the highest setting on your mower, which will encourage the health of the thinner bladed grass and allow it to spread more rapidly while crowding out that nasty thick bladed stuff that grows in short grass. I am not an expert, just a guy who grew a fescue lawn from seed and learned a lot of stuff this summer. Hope it helps.

      • ShieldsCW says:

        Roger’s entire argument revolves around the notion that everyone’s life is exactly like his, if he does things a certain way, then everyone else should do it just like him, and if he needs 300+ gallons of RoundUp, then so does everyone else. It might help to leave your county (or god forbid, visit a foreign country) every once in a while and meet people different than you. Might give you some perspective.

    • Margaux says:

      Dandelions would be a cinch. It is the “trees from Heaven” which are invasive, bindweed which spread from my neighbors yard and it is killing everything, henbit etc.
