Homemade Weed Killer Recipe (Just 3 Ingredients)

Gardening enthusiasts often face the challenge of unwanted weeds. While commercial weed killers are readily available, they can be harsh on the environment and your garden.

Enter the DIY 3 Ingredient Weed Killer – a simple, effective, and eco-friendly solution.

This homemade weed killer is easy to make with ingredients you probably already have in your pantry.


  1. Vinegar: Acts as a natural herbicide. Its acetic acid content effectively kills weeds, especially young ones.
  2. Dish Soap: Helps the mixture adhere to the weed leaves.
  3. Salt: Dehydrates and kills weeds. However, use it sparingly, as it can affect soil health.


  1. Mix Together:
    • 1 Gallon of white vinegar.
    • 1 Cup of salt (table salt or rock salt works).
    • 1 Tablespoon of liquid dish soap.
  2. How to Apply:
    • Pour the mixture into a spray bottle.
    • Spray directly onto the weeds, ensuring you coat the leaves and stems.
    • Best used on a sunny day, as sunlight accelerates the process.

Important Considerations:

  • Avoid Overspray: This mixture can kill other plants it comes into contact with, so be precise with your application.
  • Soil Health: Frequent use of salt can degrade soil quality. Use this weed killer as a spot treatment rather than a blanket solution.
  • Safety: Even though these ingredients are common household items, always wear gloves and eye protection when handling.
