The Ultimate Guide to Using 20 Vinegar as a Weed Killer

20 vinegar weed killer

Are you tired of using harmful chemicals to get rid of pesky weeds? Look no further than 20 vinegar, a natural and eco-friendly alternative that’s been gaining popularity in recent years. In this guide, we’ll explore what 20 vinegar is, how it works, and how to use it effectively.

What is 20 Vinegar?

20 vinegar, also known as horticultural vinegar, is a highly concentrated form of acetic acid. Unlike the vinegar you might use in your kitchen, which typically has an acidity level of around 5%, horticultural vinegar has an acidity level of 20%. This makes it a powerful weed killer, as it can quickly break down plant cells and dry out the leaves.

How Does 20 Vinegar Kill Weeds?

When applied to weeds, 20 vinegar works by disrupting the pH balance of the plant cells. The high acidity level causes the plant to dry out and die, usually within a day or two. It’s important to note that 20 vinegar is a non-selective herbicide, meaning it will kill any plant it comes into contact with.

Using 20 Vinegar Safely and Effectively

Before using 20 vinegar, it’s important to take some safety precautions. Wear gloves, protective eyewear, and long sleeves to avoid getting the vinegar on your skin. Because it’s highly acidic, make sure to handle it carefully and avoid inhaling any fumes.

To use 20 vinegar effectively, follow these steps:

Step 1: Choose a Dry Day

Choose a day when there’s no rain in the forecast and the temperature is above 70°F. This will help the vinegar dry more quickly and be more effective.

Step 2: Prepare Your Tools

Fill a spray bottle with undiluted 20 vinegar. Make sure to label the bottle clearly so you don’t accidentally use it for something else later on.

Step 3: Target the Weeds

Identify the weeds you want to get rid of and spray them directly with the vinegar. Be careful not to spray any plants or flowers you want to keep.

Step 4: Repeat as Needed

Depending on the size and strength of the weeds, you may need to apply 20 vinegar more than once to completely kill them off. Wait a few days after the first application, then check to see if the weeds are still alive. If they are, spray them again.

Tips for Using 20 Vinegar

To get the most out of your 20 vinegar weed killer, keep these tips in mind:

Tip 1: Use it Early

The earlier you catch weeds, the easier they are to kill. Try to spot and remove weeds as soon as you notice them.

Tip 2: Use it Often

Because 20 vinegar is non-selective, it’s important to use it often to keep new weeds from growing. Regularly spraying areas where weeds are common can help prevent them from taking over your yard.

Tip 3: Use it Carefully

Be careful when applying 20 vinegar around desirable plants, as it can easily kill them as well. Use a shield or piece of cardboard to protect nearby plants during application.

Tip 4: Store it Safely

When not in use, store 20 vinegar in a cool, dry place out of reach of children and pets. Make sure the container is tightly sealed to prevent spills.


Q: Is 20 vinegar safe for pets?

A: While 20 vinegar is non-toxic, it can be harmful if ingested in large quantities. Keep pets away from areas where 20 vinegar has been applied until it dries completely.

Q: How long does 20 vinegar take to work?

A: Depending on the strength of the weeds, it can take anywhere from a few hours to a few days for 20 vinegar to kill them off completely.

Q: Can I use 20 vinegar on my lawn?

A: No, 20 vinegar is non-selective and will kill any plants it comes into contact with. Only use it on areas where you want to get rid of weeds.

Q: Can I dilute 20 vinegar?

A: Diluting 20 vinegar will make it less effective as a weed killer. Use it undiluted for best results.

Q: Where can I buy 20 vinegar?

A: You can find 20 vinegar at most garden supply stores or online retailers.

20 vinegar is a simple and eco-friendly solution for getting rid of weeds in your yard. By following these tips and safety guidelines, you can use 20 vinegar safely and effectively to keep your yard looking its best.
