In organic gardening, vinegar can function as a natural weed killer. The acetic acid in vinegar gives it the power to kill weeds; the higher the acetic acid percentage, the deadlier it will be. The type of vinegar used for culinary purposes is relatively low in acetic acid (around 5 percent). So if you are serious about weed control, you will need to buy horticultural products with a higher acetic acid content (20 percent to 30 percent) which are available at garden supply and home improvement stores. Read on to learn a simple and effective vinegar weed killer recipe and application method for this strong mixture.
Warning
The potency of high-percentage acetic acid products used for killing weeds renders them unsafe, so use care when handling. Do not let them come in contact with your skin, and avoid touching your face when using them.
When to Apply Vinegar
When practicing natural weed control, take to heart the dictum: "Know your enemy!" Study up on the weeds you are battling before you use vinegar on them.

Annual Weeds
Learn when annual weeds set seed, so you can target them before they spawn a new generation. Depending on the weed, this can be in the spring or summer. If you catch them in time, one application of vinegar will often be enough to solve your weed problem.
Perennial Weeds
Perennial weeds are not as easy to defeat. Take dandelions as an example. It's a good idea to snap off dandelion flowers whenever you see them,so they don't propagate themselves via seeding. However, while their leaves die back in the winter, these perennials typically live on through their roots. So preventing them from going to seed is not enough. That's where applications of vinegar throughout the growing season come into play. Each time you apply the herbicide, the plant will weaken. With repeated sprayings, a final death should occur.
The Limitations of Vinegar
A commercial weed killer is usually effective after one or two tries because it's absorbed by the weed, reaching the root to permanently kill it off. Vinegar typically does topical damage to the weed unless you can apply it directly to the roots.
Because it's nonselective, vinegar is not an especially effective method for killing weeds in lawn areas. If you do so, you may end up with patches of brown lawn. It makes more sense to use vinegar in areas where lawn grass and other landscaping plants are not in the way, such as on patios or walkways where isolated weeds are pushing up through the cracks.
Reapplying
You will probably have to reapply the vinegar to get the job done. This is especially true of established perennial weeds; vinegar will be more effective on younger weeds and weeds with an annual life cycle. An example of a perennial weed is adandelion while one type of annual weed is crabgrass.
However, many herbicidal products, including organic ones, usually need a reapplication. So reapplying a natural weed killer like vinegar can be safer if used away from grassy areas. Even then, the high acidic content of herbicidal vinegar could eventually affect stone and other hard materials.
Wait for a forecast of at least a few continuous days of sunshine before you apply the vinegar.
There are two reasons why a sunny period is important. First, you need to saturate the weeds with vinegar for it to be effective, and rain would wash off too much of the vinegar from the foliage. And second, the real damage to the weeds begins in the days after the applicationwhen the sun hits the leaves.
Wear Protection
Before handling strong vinegar, put on gloves, eye protection, and secure clothing. A face mask is also highly recommended in case of splashes and spills.
Mix the Herbicide
Combine four parts vinegar to one part water. Add about an ounce of dish soap to a gallon of the mixture. Mix well in a spray bottle or other container (if you are not spraying the mix).
When reapplying horticultural vinegar during the summer as the weed growth has slowed down, you can reduce the mixture to one part vinegar and one part water with a teaspoon or so of dish soap.
The dish soap is a surfactant that improves the effectiveness of the vinegar. For an herbicide like vinegar to have the intended impact, it must stay in contact with the vegetation long enough to penetrate. This is easier said than donebecause a weed's foliage is often protected by a waxy coating that can repel attempts at penetration.The surfactant helps the vinegar grab onto the weed and remain there so the sun can help it do its damage to the plant.
If you want to zap a few tiny weeds, use undiluted household vinegar (5 percent) with a drop of dish detergent as a quick fix.
Apply the Mixture
Carefully spray or paint the vinegar onto only the weeds you wish to kill. To avoid damaging nearby plants or other materials with the mixture, paint your homemade herbicide directly onto the weeds with a brush.
If you choose to apply the mixture with a sprayer, do not pull the trigger until you are right up close to the targeted weed.
Warning
Do not spray horticultural vinegar on plants if it is breezy or windy outside. The vinegar can accidentally spray onto other plants and harm them.
Combine four parts vinegar to one part water. Add about an ounce of dish soap to a gallon of the mixture. Mix well in a spray bottle or other container (if you are not spraying the mix).
Vinegar kills weeds quickly—usually within 24 hours—but does not discriminate between the weeds you want to kill and the plants you want to grow, so apply the vinegar carefully and in the right conditions. Vinegar's efficacy depends on the weather and the solution's concentration.
Dish soap, vinegar and a spray bottle are all you need for making your own weed killer. The acetic acid in vinegar “sucks out the water” from the weed, which dries it up. The dish soap helps to break down the outer coat of the plant (cuticle), which helps that vinegar to work best.
A vinegar solution is one of the most common homemade weed killers. All you need are: Distilled white vinegar, apple cider vinegar, or cleaning vinegar. To be the most effective, the acetic acid concentration in the vinegar should be above 11% to burn and kill the plant.2.
The main ingredient in natural organic homemade weed killer is apple cider vinegar. Apple cider vinegar includes acetic acid, which kills weeds. As the apple cider vinegar mixed in water, this solution will effectively kill weeds.
The acetic acid in even household vinegar was MORE toxic than Roundup! Going one step further, in this case a comparison of rate of application is a moot point. A 1% solution of glyphosate will kill most any annual weed listed on the label, and also the majority of perennial weeds.
Mixing vinegar with Epsom salts and Dawn liquid dish soap can make a safe, effective weed killer. The more concentrated the vinegar is, the more effective it will be at killing weeds.
White vinegar is considered one of the strongest weed and grass killers, thanks to its relatively high acetic acid content. This chemical removes the moisture from weeds, killing them via dehydration, and is even more effective when mixed with a bit of dish soap to break down the plant's outer layers.
White vinegar, especially when mixed with dish soap, effectively kills weeds. The acetic acid in vinegar sucks out the water from the weed, which dries it up, while the dish soap breaks down the outside of the plant, helping the vinegar to penetrate it quicker.
Apply one cup of bleach, undiluted, to the afflicted area. Wait until the weeds turn brown before pulling them out of the ground. Run water around the area to flush the bleach, especially if you are trying to grow plants or grass in that area.
Vinegar will burn the grass's blades immediately but will not completely kill the grass. It will temporarily eliminate grass and weeds, but they will soon grow back up. Sowed seedlings less than two weeks old will be killed by vinegar.
Vinegar with a higher concentration of acetic acid tends to control weeds more effectively. Household vinegar is generally 5% acetic acid. Some herbicidal vinegar products are 20% or 30% acetic acid. In general, 20% or 30% acetic acid is more effective because it more completely kills young leaves and growing points.
What natural weed-killers kill weeds down to the roots? Boiling water and flaming will kill the roots of weeds. Vinegar kills roots, but it may take a few days for the roots to die off after the vinegar solution is applied.
The primary danger of using vinegar as a weed killer is that it will also kill your lawn or garden plants if you're not careful. If you spray too much vinegar on your yard, or if there is a light wind blowing when you do so, some of it might drift onto neighboring plants (including grass) and damage them as well.
Rock salt is actually a super-effective and totally natural weed killer that is ace at clearing a gravel driveway. Simply sprinkle some rock salt on the ground surrounding any weeds you can see and then sit back and watch as the salt kills the weeds in just a matter of days. It's almost unbelievable.
The vinegar + salt solution will probably burn the weeds down faster than glyphosate, but glyphosate would likely work slightly better over the long term, especially on large weeds.
Vinegar is an effective means of controlling weeds, but it depends on how concentrated it is. For more powerful weed killers, mix 1 part white vinegar to 2 parts Epsom salt with liquid dish soap like Dawn.
Combine distilled white vinegar, salt, and liquid dish soap in your garden sprayer or a spray bottle. Use horticultural vinegar for additional strength. Spray the leaves and stems of the weeds with your solution on a calm sunny day. Reapply the vinegar solution every 2–3 days until the weeds die out.
Distilled white vinegar is convenient to use as a herbicide if you have some in your kitchen cupboard, but it isn't very effective at killing all weeds.
Flame weeding is considered an organic method of weed removal. However, if the weather is hot and the fire danger is moderate to extreme, Roundup may be the better option to avoid accidentally starting a fire or risking fines from the local fire district or other government agency.
Shake up until combined. Let settle for 2 minutes then spray the weeds! Make sure you soak the entire weed with the formula. Let sit for a day then come back and see them dead!
This all-natural method to kill crabgrass is a great option that won't cause lasting soil damage. Simply spray the vinegar (5 percent acidity or higher) on the weed until it's drenched. Repeat a few times over the course of several days to a couple weeks, or until the crabgrass dies.
Spray undiluted bleach on the weeds and let stand.The solution will kill existing weeds and help prevent new ones from sprouting. Bleach will kill grass, flowers, and other vegetation as well, so take care where you aim!
It's extremely important to never mix vinegar and bleach or bleach and ammonia together. If combined, they create a toxic gas that can make you severely ill or can even kill you.
Mulch helps retain soil moisture, keeps soil temperatures consistent and makes the garden look tidy. But did you know it has weed-preventing properties, too? A 2- to 3-inch layer of mulch deprives weed seeds of sunlight and reduces their ability to grow.
Glyphosate is systemic, will kill grass and pretty much every other plant it touches. Used to kill annuals, perennials, woody perennials and tree stumps - it is effective against ALL weeds. Glyphosate is used with 85% of GM crops grown globally.
If you were to pour high-concentration vinegar directly onto the soil, the effects could last longer than a month, but that would be an inappropriate use of vinegar as a herbicide. Vinegar herbicides are sprayed onto plant leaves, and any drops that fall onto the soil should break down within a few days.
Even though vinegar is an acid, it breaks down quickly in the soil and, therefore, is not likely to accumulate enough to affect soil pH for more than a few days.
Typically the most effective way to kill your grass lawn is to apply an herbicide, such as glyphosate — doing so will eliminate grass and weeds all together. However, there are many different ways, natural and otherwise, that can kill your grass quickly and effectively.
Which vinegar is best for weed killing? You may know how to clean with vinegar inside the home, but this solution has its uses beyond your four walls, too. Many garden experts choose white vinegar to remove weeds, but apple cider vinegar is also approved by those who use it to fight weeds effectively.
The best way to kill the existing lawn and weeds is to apply a nonselective herbicide, such as glyphosate, over the entire area. Glyphosate is a postemergence translocated herbicide that effectively kills turf and grassy and broadleaf weeds. Glyphosate is translocated rapidly in all actively growing plants.
How to make homemade weed killer. To make homemade weed killer, stir together 1 gallon of vinegar, 1 cup of salt, and 1 tablespoon of dish soap. Pour it into a spray bottle and thoroughly spray the weeds. This solution is most effective when it's applied while weeds are actively growing, says Elworthy.
Just dissolve 1 ½ cup of baking soda and a tablespoon or two of vinegar in a gallon of water. Transfer the concoction in a spray bottle and spritz away! This solution works better as a preventive treatment so spray away on areas that are prone to weeds at weekly intervals for best results.
White vinegar with an acetic acid content of at least 5% will be required to kill most weeds effectively. Apple cider vinegar with the same acid content will also work, though, for tough perennial weeds, you may need a specialised horticultural vinegar with 20% acetic acid.
For a healthy supply of this man-made concoction, mix a gallon of white vinegar, one cup of salt, and one tablespoon of dish soap. Make sure it is properly stirred, then put the mixture in a spray bottle for easy use. You can stash the bottle in your house for repeated use.
To make the solution is simple and easy on the wallet! Pour equal parts of vinegar and Dawn into a spray bottle. Gently shake, then spray liberally onto the surface to be cleaned. I have found the best results is when I use it to clean chrome shower and sink fixtures.
Although mixing vinegar and baking soda is not considered dangerous, you should still avoid mixing these in a container. Vinegar is acidic and basic soda is basic, so the by-products are sodium acetate, carbon dioxide, and water that are not toxic.
