Best All Natural Homemade Weed Killer 3 Ingredient Recipe

Vinegar Homemade Weed Killer vs. Roundup Herbicide

Vinegar is often hailed as a homemade weed killer alternative to Roundup, the popular herbicide containing glyphosate. As concerns about the environmental and health impacts of chemical-based weed killers have grown, many people are seeking safer alternatives for weed control. Vinegar has gained popularity as a natural option due to its potential effectiveness and low environmental impact.

One of the main reasons vinegar is considered a natural alternative to Roundup is its active ingredient: acetic acid. Vinegar typically contains acetic acid in varying concentrations, with higher concentrations, such as 20% or 30%, being more effective for weed control. When applied to the leaves of unwanted plants, the acetic acid in vinegar acts as a desiccant, causing the plant cells to dry out and leading to their eventual demise. This makes vinegar particularly effective for killing young, tender weeds and annual plants.

Unlike chemical herbicides, vinegar is biodegradable and breaks down relatively quickly in the environment. This starkly contrasts glyphosate-based products like Roundup, which can persist in the soil and water for extended periods. Vinegar does not leave harmful residues in the soil, making it a more environmentally friendly option.

However, it is important to note that homemade weed killer has some limitations. While vinegar can be effective against many common weeds, it may not be as potent or long-lasting as chemical herbicides like Roundup. Persistent or deep-rooted weeds may require multiple applications or additional weed control methods to eradicate them fully.

Furthermore, vinegar-based homemade weed killers are non-selective, meaning they can harm or kill any plant they encounter. Care must be taken to avoid spraying desirable plants or vegetation. Targeted spraying directly onto the leaves of the weeds is crucial to minimize unintended damage.

To enhance the effectiveness of homemade weed killers, some recipes recommend adding salt and dish soap. The salt helps draw out moisture from the plants, intensifying the desiccation effect, while the dish soap acts as a surfactant, helping the vinegar adhere to the plant’s leaves. These additions can improve the performance of the vinegar solution, but it’s important to be mindful of the potential negative effects of salt on the soil and beneficial organisms.

Like many people, I share concerns about the abundance of chemicals in our food and the environment. It’s logical that the more harmful chemicals we use, the more damage we inflict on ourselves and our surroundings. However, it’s hard to deny that spraying stubborn weeds is much easier and more efficient than manually removing them.

As a horticultural specialist and licensed pest control operator, I didn’t want to spend my valuable time pulling weeds. This dilemma motivated me to explore the homemade weed killer recipes I had come across in recent years. My initial attempt with the original homemade weed killer recipe was underwhelming. While the weeds turned slightly brown, there was no dramatic weed demise that I had hoped for, as I had seen with commercial weed killers.

Nonetheless, I was determined to sever ties with broad-spectrum glyphosate-based herbicides. I conducted further research and experimentation into natural weed killers using vinegar and dish soap, while also adjusting my expectations.

I’ve discovered a few things about homemade weed killer:

  1. Homemade weed killer recipes will never match the strength and effectiveness of commercial chemical products. It’s crucial to adjust your expectations accordingly.
  2. Commercial products tend to be more effective in killing the roots of weeds with just one application. Homemade vinegar weed killers may require multiple applications to eradicate the weed fully. For example, when I sprayed my homemade vinegar weed killer on mint, I noticed some new growth at the base after a week. I applied more vinegar to those sprouts, and a week later, there was no further green growth. However, it’s worth noting that mint is particularly resilient.
  3. Homemade weed killers can sometimes eliminate weeds effectively on the first try, while other times, additional sprays may be necessary.
  4. The homemade vinegar weed killer will affect anything it comes into contact with, intentionally or unintentionally. I learned this the hard way when I accidentally sprayed my lawn, and a couple of days later, I noticed a path of dead grass. It’s important to be mindful of where you spray to avoid unintended damage.
  5. A wind-free, dry, and sunny day is optimal for using this natural weed killer recipe.
  6. This spray targets the leaves and cell tissues of the plants and does not affect weed seeds.
  7. As with any homemade weed killer, it’s crucial to spray directly onto the leaves of the weed, vine, or plant. Excessive salt in the soil can be detrimental. I take care to avoid wide broadcasting of my vinegar weed spray and focus on targeting specific weeds. This approach has allowed me to use the spray without any issues in areas where I also want desirable plants to grow.

Despite the mentioned caveats, I can’t envision going back to commercial, chemical-laden weed killers. The extensive information regarding the cancer risks and environmental damage associated with these products is enough for me to accept spraying my persistent weeds two or three times for control. It’s a small price to pay for peace of mind.

Industrial 30% Vinegar Compared to 5% Household Vinegar

Regarding vinegar selection for the homemade weed killer, plain household vinegar is not potent enough. Household vinegar typically contains around 5% acetic acid, which may only kill very young or tender weeds, but not more robust and resilient ones. To tackle serious weeds, a minimum of 30% acetic acid, and even up to 45%, is necessary. Personally, I opt for the 45% vinegar because it is priced the same as the 30%.

It’s crucial to note that the 30% and 45% vinegars can cause skin burns. While I haven’t noticed any lasting marks, you can certainly feel the burn upon contact. It is important to exercise caution and avoid contact with your skin, eyes, and inhalation of the vinegar’s strong acidic fumes. The 30% and 45% vinegars are available for around $20 per gallon on platforms like Amazon, making them comparable in price to pre-mixed commercial weed killers.

Let’s delve into the ingredients of this homemade weed killer recipe and their purposes:

  1. 30-45% Vinegar: The key ingredient we need is acetic acid, which is found in vinegar. Acetic acid works by dissolving the plant cell membranes, leading to the drying out and eventual death of the plant tissues.
  2. Salt: Salt plays a role in drawing water from the plant cells, causing them to dry out and die.
  3. Liquid Dish Soap: The dish soap acts as a surfactant, reducing the surface tension between the vinegar-salt solution and the leaf surface. This allows the vinegar-salt solution to better access the plant tissues.

While the vinegar and salt combination can be effective in killing weeds, it is important to acknowledge the drawbacks associated with using salt as a weed control method. Excessive salt in the soil can harm beneficial bacteria and earthworms, as well as hinder the roots’ ability to absorb moisture. However, by being aware of these risks and ensuring targeted spraying on weed leaves rather than wide application, you can minimize the potentially damaging effects of salt.

The vinegar homemade weed killer recipe you provided is a popular natural weed control option.

Here’s a summary of the homemade weed killer recipe and some additional information:


  • 2 quarts (approximately 1.9 liters) of 30% vinegar product (such as Shine)
  • 3 tablespoons of salt (table salt or rock salt)
  • 1 tablespoon of dish soap (any brand)


  1. Mix the 30% vinegar, salt, and dish soap together in a half-gallon container.
  2. Shake the mixture well before using it in a sprayer with a pump.

Cautionary Statement about homemade weed killer

Remember to use caution when handling any homemade weed killer solutions and read and follow all safety instructions on the product labels. It’s also advisable to test the solution on a small area first to ensure it doesn’t harm desired plants.

Lastly, I must emphasize that I can provide information and suggestions, but I cannot guarantee the outcome or be held liable for any property damage or injury resulting from the use of this information. It’s always important to use any homemade weed control solutions at your own risk and discretion.
