Homemade Organic Weed Killer: A Natural Solution for Your Garden

Are you tired of using chemical-based weed killers that can harm the environment and pose a risk to your health? If so, then it's time to switch to homemade organic weed killer solutions. Not only are they safe and eco-friendly, but they're also easy to make and just as effective as their commercial counterparts.

In this article, we'll share some of the best homemade organic weed killer recipes you can try at home. But first, let's take a closer look at why organic weed killers are a better choice for your garden.

The Benefits of Using Organic Weed Killers

Organic weed killers offer several benefits over their chemical-based counterparts. Here are some of the most significant advantages:

Safe for the Environment

Chemical-based weed killers can contaminate the soil, water, and air, which can have harmful effects on the environment. Organic weed killers, on the other hand, are made from natural ingredients that won't harm the environment.


Commercial weed killers contain toxic chemicals that can be harmful to humans and pets. Organic weed killers, however, are non-toxic, making them a safer option for your family and pets.

Cheap and Easy to Make

You don't need to spend a lot of money on commercial weed killers when you can make your own for a fraction of the cost. Plus, most of the ingredients you need are likely already in your pantry or garden.

Just as Effective

Contrary to popular belief, organic weed killers are just as effective as their commercial counterparts. With the right ingredients and application, you can get rid of weeds without harming your garden or the environment.

Now that we've covered the benefits of using organic weed killers, let's take a look at some homemade recipes you can try.

Homemade Organic Weed Killer Recipes

Vinegar and Salt Solution

One of the most popular and effective homemade weed killers is a vinegar and salt solution. Here's how to make it:

  • Mix one gallon of white vinegar with one cup of table salt and a tablespoon of dish soap.
  • Stir the mixture until the salt dissolves.
  • Transfer the solution to a spray bottle and apply it directly onto the weeds.

Note: Be careful when using this solution near plants you want to keep. The high concentration of salt can damage plant roots and kill them.


Cornmeal is a natural pre-emergent herbicide that can prevent weeds from growing. Here's how to use it:

  • Sprinkle cornmeal over the soil where you want to prevent weed growth.
  • Water the area thoroughly to activate the cornmeal.
  • Reapply the cornmeal every four to six weeks.

Boiling Water

Boiling water is a simple yet effective weed killer that works by destroying the cells in the plant's leaves and stem. Here's how to use it:

  • Bring a pot of water to a boil.
  • Carefully pour the boiling water directly onto the weeds, making sure not to splash any on nearby plants.
  • Repeat as necessary.

Essential Oil Spray

Essential oils such as clove, cinnamon, and peppermint can be used to create an effective weed-killing spray. Here's how to make it:

  • Mix 10-15 drops of your preferred essential oil with one quart of water and a teaspoon of dish soap.
  • Transfer the solution to a spray bottle and apply it directly onto the weeds.

Other Tips for Weed Control

In addition to using homemade organic weed killers, there are other things you can do to prevent weed growth in your garden. Here are some tips:


Mulching is an effective way to prevent weeds from growing by blocking out sunlight and reducing soil moisture levels. Apply a thick layer of mulch around your plants to keep weeds at bay.

Weed Early and Often

The earlier you catch weeds, the easier they are to remove. Make sure to weed your garden regularly, even if you don't see any visible weeds. This will help prevent them from taking root and spreading.

Hand Pulling

Sometimes, the best way to get rid of weeds is to pull them out manually. Use a garden fork or trowel to loosen the soil around the weed's roots, then gently pull it out.
