How to Combine Vinegar and Roundup

Quck answer

Vinegar can be mixed with Roundup as a natural alternative to the herbicide. This mixture can be effective in killing weeds, especially when applied directly to the leaves. To mix vinegar with Roundup, follow these steps:

1. Choose a vinegar with a high acidity level, such as white vinegar or apple cider vinegar.

2. Dilute the vinegar with water in a 1:1 ratio.

3. Add the diluted vinegar to the Roundup concentrate according to the product’s instructions.

4. Mix well and transfer the mixture to a sprayer.

5. Apply the vinegar and Roundup mixture directly to the weeds, avoiding any desirable plants.

6. Repeat the application if necessary.

Remember to wear protective clothing and follow all safety precautions when working with herbicides.


Roundup is a well-known herbicide that contains glyphosate, an active ingredient that kills various weeds and plants. While it is effective on its own, vinegar can enhance its potency and effectiveness. Vinegar is known for its ability to quickly dry out plants and speed up their removal. Even those without experience can create this mixture in less than 15 minutes.

Step 1

Unscrew the cap of a Roundup bottle and the top of an empty plastic spray bottle.

Step 2

Place a plastic funnel into the opening of the empty plastic spray bottle.

Step 3

Carefully pour four parts Roundup and one part white vinegar into the funnel of the plastic spray bottle. Be sure to maintain the correct ratio of Roundup to vinegar. Using an incorrect mixture can result in an ineffective or weakened weed killer.

Step 4

Remove the funnel from the spray bottle and screw the cap back on tightly. Shake the bottle to thoroughly mix the solution.
