Does Vinegar Kill Weeds to the Root?
Killing weeds with vinegar
Filling a pickle jar or simply flavoring your food are not the only purposes vinegar has; it adds more to the table. Certainly, vinegar will kill weeds. To determine whether vinegar successfully kills weeds at the root, we must first understand how vinegar works.
Vinegar contains acetic acid, which acts as a non-selective herbicide. The acidity of the vinegar burns any plants it lands on by destroying the plant’s cell membrane. The acetic acid sucks out the water from the weed’s leaves and kills them before reaching the root.
After 24 hours, the leaves turn brown, tricking most gardeners into thinking the plant is dead. Only to be startled when the plants return with a fury.
Acetic acid, which burns off any organic material it comes into contact with, is the fatal weed-killing element in vinegar. As a result, you will see browning of the leaves within 24 hours of applying it.
However, unlike commercial weed killers, acetic acid is not absorbed in the plant’s system. It is also swiftly broken down into harmless acetate salts in the soil.
This is not to say that vinegar does not kill the roots of some weeds. It is particularly successful in killing the root system of weeds that are less than two weeks old, but it can be challenging to kill the weeds to the roots once they have matured.
Mature plants have robust root systems, but vinegar will only be effective after a few reapplications to keep the weeds at bay.
The advantage of vinegar as a weedkiller
It is simple to get vinegar from your cupboard. As a result, vinegar is a cost-effective weed killer that is relatively easy to buy.
Vinegar is a natural weed killer; therefore, it is free of poisonous chemicals harmful to the environment. Acetic acid, the active element in vinegar, is created spontaneously by bacterial fermentation.
Because vinegar is a contact herbicide, it is effective against broadleaf and tiny delicate weeds. However, it can also be used to manage ancient weeds, perennials, and grass stickers when combined with other chemicals such as salt and dish soap and reapplied several times.
The disadvantage of vinegar as a weedkiller
Although vinegar is an effective natural weedkiller, it does have a few downsides. Most significantly, vinegar is a non-selective contact weed killer.
It means it will destroy any plant it comes into contact with, including your prized plants. Furthermore, highly concentrated horticultural vinegar can cause skin burns and severe eye injuries when sprayed without protective clothing.
Vinegar has only been shown to successfully destroy the part of the plant above ground, which implies that it will need to be used in conjunction with other weed control programs to kill weeds with deep roots, such as dandelion, efficiently. Otherwise, the weeds will return the following year.

Multiple vinegar applications will kill the weed, but you risk compromising the pH balance of your soil owing to the accumulation of acetic acid in the soil.
However, depending on how long you have been applying the vinegar, this will resolve within a few days. As a result, use vinegar with caution.
Will 20 percent acetic acid kills weeds
To effectively eliminate the weeds, you must destroy their entire system, most notably their roots. Vinegar kills weeds exclusively through contact instead of commercial weed killers, which systematically destroy weeds.
Because of this, even highly concentrated kinds of vinegar, such as horticultural vinegar, will not successfully kill weeds unless administered several times.
In addition, even when concentrated on the soil, vinegar does not penetrate the roots. Since acetic acid is broken down into acetate salt, which is not toxic, if you are serious about weed control using vinegar, go for one with a higher percentage.
FAQs About Vinegar as a Weed Killer
Does vinegar kill weeds permanently?
Yes, vinegar is an efficient weed killer, but it only works after several reapplications. The higher the acetic acid content, the more effectively it acts.
How do you mix vinegar to kill weeds?
A homemade weed killer recipe of vinegar combined with salt and dish soap is the best for killing weeds. Use 1 gallon of vinegar mixed with a cup of salt and two tablespoons of dish soap.
Is vinegar as good as Roundup?
Because acetic acid is a contact weed killer and Roundup is a systemic weed killer, Roundup is more effective than vinegar. Still, it is more lethal and toxic than vinegar because it contains glyphosate.
Don’t be left behind as organic gardening takes over, with vinegar and other elements leading the way. Vinegar has long been used for various purposes.
