How to Use Vinegar as a Weed Killer [Explained] {Updated}

Vinegar might be used as a sustainable weed remover to control weed growth in sustainable farming.

Vinegar’s ability to eradicate weeds is attributed to the presence of acetic acid; the greater the concentration of acetic acid, the more lethal the vinegar.

First, keep in mind that the vinegar utilized for culinary reasons has a low concentration of acetic acid, usually around five to six percent.

If users are genuine about weed management, they need to purchase horticultural items with a greater concentration of acetic acid, around 20-30%, accessible in garden departments and home improvement outlets.


  1. Use caution while managing high-percentage acetic acid compounds since their concentration is potentially hazardous to human health and the environment.
  2. While employing them, avoid permitting them to come into an interface with the skin and prevent contacting the face.

When Should Vinegar Be Used?

“What is the problem?” is a phrase that should be considered while practicing natural weed management. Prepare yourself by learning everything users can learn about the weeds they are fighting before using vinegar.

Annual Weeds

Recognize whenever annual weeds generate seedlings so that users can eradicate them before producing a new cycle of weeds. It can occur in either the springtime or early summertime based on the weed.

If users identify the weeds early enough, a single vinegar treatment will frequently be sufficient to eliminate the weed problem.

Perennial Weeds

Perennial weeds are more challenging to eradicate. Consider the case of dandelions. It’s a great practice to pick dandelion blooms off the ground anytime users see them, preventing them from spreading by seed.

Although their leaves die down in the wintertime, these perennials often survive through the roots in the springtime. As a result, simply restricting them from growing to seed is insufficient.

This is where vinegar treatments during the growing season come into the equation. The growth will become weaker with each application of the herbicide. Frequent sprayings should bring about the ultimate demise. 

Vinegar’s Restrictions on Usage

A professional weed remover is generally successful after one or two applications. It is consumed by the weed and travels to the roots, where it is killed irreversibly.

Assuming users can administer vinegar directly to the weed’s origins, it will often just cause surface degradation to the plant. 

Vinegar is not particularly good at eradicating weeds in grassland regions since it is nonselective in nature. If users do this, they may wind up with areas of brown turf on their hands and feet. It is more practical to apply vinegar in locations where lawn grass and other landscape vegetation aren’t in the way, especially on patios or walks where isolated weeds are making their way up through the cracks.


Users will likely have to administer the vinegar several times to achieve the task. Vinegar will be more successful on youthful weeds and wildflowers with an annual life span than on entrenched vegetation, particularly for entrenched vegetation.

Dandelion is an illustration of a perennial weed, whereas crabgrass is an illustration of an annual weed.

Several herbicidal products, even organic ones, must, nevertheless, be reapplied after a certain period. When employed away from grasslands, it is possible to be safer when reapplying for organic weed control such as vinegar.

Especially in that case, the strong acidic concentration of herbicidal vinegar may gradually cause damage to stone as well as other base materials such as marble.

Steps to Use Vinegar as a Weed Killer

1. Sit tight for a period of warm conditions.

Before applying the vinegar, pause until there is a prediction for a few days of sunshine.

There really are two main explanations why having a sunny phase is beneficial. First, the weeds must be completely saturated with vinegar, and rainfall would wipe away far too much of the vinegar from the leaves for it to be successful. Secondly, whenever the sun reaches the leaves of the weeds in the hours after the treatment, the true destruction is done to the plant’s leaves.

2. Protective Clothing.

Putting on protective gloves, goggles, and long-sleeved garments whenever working with potent vinegar. In case of spills or splashing, a face shield is often strongly suggested for protection.

3. Combine the herbicides.

Three parts of vinegar to one part of the liquid is a good ratio. Pour a gallon of the solution into a dish soap container and shake well. In spraying bottles or other containers, combine the ingredients thoroughly.

Reapply horticultural vinegar over the spring and summer months once weed growth has halted. The process can be accomplished by diluting the solution to an equal part of vinegar and water. A spoonful or so of cleaning solution is added to the liquid.

Vinegar is more successful when combined with dish soap, which acts as a surfactant. A herbicide such as vinegar must be in touch with the plant for an extended period to have the desired effect. This is simpler said than achieved, however, since the foliage of weeds is frequently coated by a waxy layer that makes it difficult to penetrate the plant. The surfactants aid vinegar’s adhesion to the weed and its retention on the weed so that the sunlight can aid in destroying the crop.


Using undiluted home vinegar (five to six percent concentration) and a sprinkle of dish soap as a rapid remedy for a few little weeds is good enough in most cases.

4. Put the Mixture to Use

Spritz or apply the vinegar on just the weeds users want to destroy, cautious not to get any on themselves. Paint the homemade pesticide firmly into the weeds with a paintbrush to minimize contaminating neighboring flowers or other items with the concoction.

If users decide to use spraying to administer the solution, wait until they are really close to the weed they want to aim before pulling the trigger.


If it’s breezy or stormy outdoors, avoid spraying horticultural vinegar on crops to protect them. Reckless spraying of the vinegar can cause damage to nearby vegetation.
