Will Vinegar Kill Dandelions?

You may get rid of your weeds by using the natural acidity of white vinegar or apple cider vinegar. Simply fill a spray bottle with pure vinegar and mist the undesirable plant with it until it is completely covered. The leaves will wilt and become brown in a few hours. This will hasten the dandelion’s demise if done on a hot, sunny day. Pull the plant out once it has died back and wet the area down.

Does vinegar permanently eradicate dandelion weeds?

There is a 50/50 chance that vinegar will permanently eradicate dandelions. The age of the dandelion and the level of acetic acid are the determining factors. Strong enough vinegar cannot eradicate well-established, deeply-rooted dandelion plants. Vinegar only burns the leaves of dandelions, which have lengthy taproots measuring 8 to 16 inches. The substantial, deep roots are still there to support future growth.

Young dandelion plants can be killed permanently by high acetic acid concentrations of around 20%. Apply the vinegar in the fall when dandelions store sugars in their roots for the winter. Spraying vinegar on established dandelions and removing them within three days of death will permanently eliminate them.

Do dandelion roots get killed by vinegar?

Is there a remedy I can spray on dandelions rather than removing them by hand? Does vinegar, dawn soap, and Epson salts work in place of Roundup? Or is there one that’s better?


Dandelion plants have a long (6–18 inch) tap root that can regenerate in small sections, making them challenging to eradicate. Dandelions are weeds that live for many years and are perennial. In the fall, they shed their leaves, and in the spring, they re-grow.

The best time to eradicate them is in the fall when dandelions are storing sugars in their roots for the winter. Herbicides will also be absorbed into the roots at this time to aid in dandelion eradication. Dandelions respond well to the brush killer triclopyr, which does not harm grasses. To ensure correct dilution, safety, and application rates, make sure to thoroughly follow the instructions on the herbicide package.

The strength of regular vinegar is insufficient to eradicate dandelions. Only 5% of household vinegar contains acetic acid. 20% acetic acid is present in agricultural vinegar, which is used to destroy weeds. That acid is extremely potent and can seriously harm you.

The strength of regular vinegar is insufficient to eradicate dandelions. Only 5% of household vinegar contains acetic acid. 20% acetic acid is present in agricultural vinegar, which is used to destroy weeds. That acid is extremely potent and can seriously harm you. To avoid getting horticultural vinegar in your eyes, using it calls for gloves, long sleeves and pants, and a mask. The other issue with vinegar is that while it kills the leaves, the tap root is still there, allowing the dandelion to reappear.

Dandelions won’t be harmed by Dawn detergent, and epsom salts include magnesium sulfate. Epsom salts can supplement your soil’s lack of magnesium by functioning as a fertilizer.

The easiest technique to control dandelions without using herbicides is to pull them when the soil is damp and soft so that a large portion of the tap root can be removed. The dandelion can also be cut off 4-5 inches below the surface.

To prevent light from reaching the leaves, cover the area with a mulch made of wood chips or finely chopped bark that is buried at least three inches thick. Blocking the light will eventually starve the plant to death because leaves require light to operate.

Finally, remove dandelion blossoms to stop them from maturing into seeds and further dispersing the weeds.

How long does it take for vinegar to eradicate dandelion?

A: Using commercial weed killers close to fruit or vegetable plants can raise safety concerns about some of the chemicals in such products. Is vinegar effective at killing weeds? You are fortunate. When used properly, vinegar can destroy weeds effectively. It is a natural herbicide and is equally safe to use while dressing a salad as vinaigrette. Additionally, vinegar comes in huge bottles that are affordable and practical for cooking and cleaning, so it is not a one-use item that will collect dust on a garage shelf.

Vinegar kills weeds quickly—usually within 24 hours—but it has no preference for the plants you want to grow or the weeds you want to destroy, so use it sparingly and under the correct circumstances. The concentration of the solution and the weather both affect vinegar’s effectiveness. A expert can handle the problem if the weeds are severe or if you are concerned about the integrity of your garden.

What causes dandelions to die but not grass?

There are various approaches to dandelion management. Every year, all dandelion-removal techniques must be used. Dandelion weeds are difficult, if not impossible, to eradicate permanently from a garden or lawn because their seeds can travel many kilometers on the wind.

How to Kill Dandelions with Herbicide

On dandelions, two different forms of herbicide can be applied. A selective broadleaf herbicide is the first. Only broadleaf weeds, like dandelion, can be eliminated with broadleaf herbicides. A broadleaf herbicide works well for eliminating weeds in lawns since it only kills weeds and not grass.

Non-selective herbicides are another type of powerful dandelion herbicide. Non-selective indicates that any plant it comes into touch with will be killed by the herbicide. Using a non-selective herbicide to eradicate dandelion weeds in certain areas, such as flowerbeds and walkways, is beneficial.

The optimal time to use a herbicide to limit dandelion growth is prior to the dandelion developing blossoms. When dandelion blooms appear, the plant becomes far more resistant to herbicides, making broadleaf or non-selective herbicides ineffective.

Hand Digging for Dandelion Removal

Digging dandelion patches by hand is the most efficient yet time-consuming way of dandelion control. When the first dandelion seedlings emerge in the spring, hand digging should be done. To assist with hand digging, specialized “dandelion pullers or comparable instruments can be purchased.

It’s crucial to keep in mind that the entire dandelion taproot must be removed when using hand digging to eradicate dandelions. Dandelion taproots can extend far.

It is doubtful that you will eliminate every dandelion in your yard during the initial round of hand digging because dandelion taproots grow deep. Hand-dig any re-emerging dandelions from their taproots every several weeks.

Using a Pre-Emergent for Dandelion Control

A chemical called a pre-emergent can be used on your lawn or flowerbed to stop seeds from sprouting. To be effective, a pre-emergent for dandelion management must be used in the late winter. Only when applied before the dandelion seeds have had an opportunity to germinate will the pre-emergent successfully prevent the dandelion seeds from growing.

The most crucial thing to remember when using any of the several methods for weed control is that you must stop the dandelions from setting seed. The amount of dandelion plants in your yard (and your neighbor’s) will increase after the fluffy seed heads arrive.

However, now that you know how to get rid of them, you can be sure that with a little time and effort, your yard will be free of dandelion infestations.

Recall that organic methods of control are more environmentally friendly and should only be employed as a last option.

After vinegar, will grass grow back?

Can Grass Regrow After Vinegar Treatment? Yes, barring grass seedlings that are younger than two weeks old. In that situation, the roots are not sufficiently established to produce new blades. The roots of broadleaf grasses will still produce new leaf blades even though they are more prone to die back to the soil.

Is vinegar just as effective as Roundup?

Rain produces grain. is a proverb that has been around for years that you might hear whenever two or more farmers are together and a midsummer shower appears. Although that proverb may be accurate, it’s also a fact that rain causes weeds.

Due to this year’s record-breaking rains, the landscape is full of highly robust, quickly spreading weeds. Homeowners are calling in to ask for “safe” ways to control those weeds as well. Vinegar is one product that is usually recommended for weed control in landscaping. A simple inquiry about vinegar frequently leads to a discussion on pesticides, toxins, the legality of its use, and what exactly “safer” implies.

Let’s start by stating that vinegar does, in fact, have some weed-controlling capabilities. In Ohio, there are currently three vinegar products with labels. The fact that they are labeled indicates that using them to manage pests is allowed, but only one of the three in Ohio is classified as a herbicide. Common household vinegar is neither “labeled” nor “authorized for use as a herbicide in Ohio,” which may be difficult for some people to comprehend.

In any case, when we see what happens to weeds when vinegar is applied, we see that the acetic acid in the vinegar “burns” through the wax coating on the surface of the leaves and kills those leaves. Annual weeds like foxtail, crabgrass, and ragweed may only require one application of the specified 20% acetic acid vinegar to eradicate them if they are little at the time of application. In contrast, household vinegar contains only 5% acetic acid. It can require more than one application if the annuals get larger before the treatment. It should be noted that when vinegar is sprayed on perpetual weeds like ground ivy, the leaves may burn and the plant will probably develop new leaves. Although vinegar can ‘manage’ perennial weeds, it seldom kills them.

We have already discussed vinegar’s acetic “acid” and the plants it “kills” in previous discussions. It’s vital to note that a product certainly has harmful effects if it kills a plant—in this example, what some would term a “natural” herbicide like vinegar! So, is it safe, or can it be “safer” than a commercial herbicide made from synthetic materials? I’ll let you make that decision as we go.

We must comprehend toxicity while we reflect on that query. The Environmental Protection Agency (EPA) undertakes research to ascertain the toxicity, or Lethal Dosage (LD50) Values, of all pesticides and many other goods we frequently use, including what many people prefer to refer to as “natural” things like vinegar. The benchmark test for acute toxicity used to compare all the evaluated goods is called an LD50. The LD50 is expressed as the individual dose necessary to kill 50% of a population of test animals and is expressed in milligrams (mg) of pesticide per kilogram (kg) of body weight (e.g., rats, fish, mice, cockroaches).

Most people who inquire about using vinegar as a herbicide want to know how it compares to glyphosate, which is frequently marketed under the trade name Roundup. EPA tested glyphosate, just like it does with all pesticides, and assigned it an LD50 value. Similarly, the EPA tested and assigned an LD50 to acetic acid, which is exactly the same as the acid found in vinegar. The LD50 values for glyphosate and acetic acid, respectively, were 5600 and 3310 when rats were the test subjects.

An LD50 figure tells us how much of an individual dose is needed to kill 50% of the test population, and the lower the number, the more deadly the substance is. In a lab test, acetic acid killed rats more quickly than glyphosate did when administered orally in identical amounts. Even common vinegar was more hazardous than Roundup due of its acetic acid content.

Going one step further, it is irrelevant to compare application rates in this situation. Most annual weeds indicated on the label can be killed with a 1% solution of glyphosate, as can most perennial weeds. The annual weeds we find in the landscape may require more than one application of a 20% acetic acid product in order to completely eradicate them.

This discussion does not imply that vinegar is a bad herbicide. The goal is to raise awareness that a substance is toxic whether it is considered “natural” or synthetically produced, as long as it has the power to kill plants or insects. Each poison should be handled carefully, used for the intended purpose specified on the label, and applied at the rate deemed to be acceptable. Both organic and synthetic herbicides can be secure and efficient when handled appropriately.

What eradicates dandelions for good?

This dandelion was scratched soon before a weedkiller was sprayed on it. It suddenly and completely vanished, never to be seen again. As plants naturally transfer elements from leaves to roots for winter storage, the optimum time to spray dandelions is in the fall. Applying weedkiller in the fall allows it to reach the roots directly, helping to eliminate dandelions forever. However, avoid using lawn weed and feed solutions in the fall to get rid of dandelions since if your lawn remains dormant for the winter, the fertilizer won’t be absorbed. Any weeds that are there instead absorb the fertilizer and become more robust.

What method gets rid of dandelions the quickest?

Spraying dandelions using a broadleaf herbicide that kills the entire plant, not just the leaves, and doesn’t hurt the nearby grass is the quickest and least time-consuming way to get rid of them. But many people would want to avoid the dangerous chemicals and choose a more natural option. If you want to do that, you should think about using this long-term, multifaceted strategy to get rid of dandelions from your yard.

Are dandelion seeds killed by vinegar and dish soap?

I abhor weeds. You do not? There are many different weed killers to pick from if you visit the gardening section of your neighborhood nursery or large box retailer. But what if there was a natural way to get rid of weeds without needing to buy one of those pricey weed killers? Did you realize that your cabinets likely contain a perfectly fine weed killer? Vinegar, that is! Yes, it is true that vinegar kills weeds, particularly when used in conjunction with dish soap.

You only need a spray bottle, dish soap, and vinegar to make your own weed killer. The vinegar’s acetic acid “sucks out the water from the weed, drying it out.” The vinegar works best when the cuticle, the plant’s outer covering, is broken down by the dish soap. See how to spot weeds in your garden below.

I have to say that I am quite pleased with the outcomes. The recipe for manufacturing your own vinegar/soap weed killer is as follows:

DIY Weed Killer Recipe

  • 1 gallon of 5% acetic acid vinegar
  • Dish soap, 1 ounce
  • bottle of plastic spray.

Spray the mixture onto weeds after combining the vinegar and soap in a spray bottle.

Application Tips

Here are some recommendations before using this weed killer in your garden:

  • Because vinegar/soap weed killer is non-selective, it will also harm or destroy your prized plants. So use caution when spraying weeds.
  • Apply on a wind-free, sunny day. The sun aids in the vinegar’s ability to dry the weed. Additionally, you should wait for a windless day to avoid accidentally spraying other plants with your spray.
  • The root of the weed may or may not be killed by your vinegar weed killer. If green growth begins to appear thereafter, you might need to reapply it. You can also spray some weed killer over the root zone to completely eliminate huge weeds.
  • Not all weed varieties will be eliminated with the vinegar/soap weed killer. Try it out in your garden to see what kinds of weeds it kills.

So the next time you need to get rid of weeds, just go to your pantry and get some vinegar and soap to manufacture your own weed killer. It’s organic, efficient, and affordable! Seek out more strategies for weed control.
