Last Updated on May 21, 2024 by Shavy Jain

Weeds in your garden are bad news. So is their treatment plan. Industrial pesticides wreak havoc on our environment and our natural food chain. 

In response to the growing demand for sustainable gardening practices, organic weed killers have emerged as a powerful alternative to traditional and highly toxic pesticides. These natural weed suppression solutions, known as organic herbicides, offer a non-toxic weed management approach that is both pet-friendly and environmentally safe. 

If you’re someone who prioritizes both efficacy and ecological responsibility, we’ve made a list of the top 10 organic weed killer for lawns for you, along with an organic weed killer recipe that you can make at home immediately. 

What are Lawn Weeds?

Weeds are the unwanted scourge that grows around your produce, as a natural consequence of maintaining a fertilized and well-cared-for field. These opportunistic plants thrive in cultivated environments, where they compete with crops or ornamental plants for essential resources such as light, water, nutrients, and space. 

When not cared for, lawn weeds can pose significant challenges for agricultural productivity and ecological balance of a field. When not controlled, they can become a huge problem.

For decades, farmers have used twice as much herbicides and other toxic products to deal with intensified weed growth. But the over dependence on herbicides isn’t great for the environment. It can mess up the soil, get into rivers and lakes, and even make some weeds tougher to kill over time.

The solution? Organic weed killers that are both safe for the environment, and effective in eliminating the unforturnate qeed sprawl on your lawn.

What Is An Organic Weed Killer?

An organic weed killer is made of natural substances instead of synthetic chemicals. These organic options often come from plants, minerals, or other natural sources, and they aim to be less harmful to the environment, people, pets, and beneficial insects. Common ingredients in organic weed killers might include vinegar (acetic acid), corn gluten meal, citrus oil, or essential oils known for their herbicidal properties.

The two kinds of organic weed killers, selective and non-selective, are designed for broader and specific use respectively.

Non-selective, or total weed killers are robust solutions typically employed in areas where complete vegetation removal is necessary. On the other hand, selective organic herbicides are engineered to target specific weed species.

Organic Weed Killer Home Recipe

We promised a simple recipe for an organic weed killer that you can easily make at home, and here it is. With simple ingredients and three simple steps, you can make an effective and safe weed killer at home.

Ingredients

• White Vinegar: 1 gallon (4 liters) – Vinegar contains acetic acid which helps to burn the foliage of weeds.
• Salt: 1 cup – Salt dehydrates plants and disrupts the internal water balance of plant cells.
• Dish Soap: 1 tablespoon – Soap acts as a surfactant, which reduces the surface tension of the vinegar, helping it stick to the weeds more effectively.

Instructions

1. Combine Ingredients:
   
   • In a large container, mix the vinegar and salt.
   • Stir until the salt is completely dissolved.
   • Add the dish soap to the mixture and stir gently to combine without creating too much foam.
     
2. Application:
   
   • Pour the solution into a spray bottle for easy application.
   • Spray the weeds directly with the solution, coating them thoroughly. The best time to do this is on a sunny day, as the heat helps to accelerate the process.
   • Be careful to target only the weeds, as this mixture can harm your other plants as well.
     

How Do You Spray Organic Weed Killer Effectively?

Spraying organic weed killers is no rocket science. But there are ways in which you can be careful and strategic about the process to make the most out of the product. 

Before we begin, make sure that you’re following the safety procedure. Wear protective clothing, gloves, and eyewear, and avoid spraying on windy days to prevent drift.

Now, here’s the entire step by step process of spraying weed killers:

Step 1: Read the label carefully to ensure proper application. Every organic weed killer comes with specific instructions about the spraying process. 

Step 2: Choose the right time. Spray when weeds are actively growing, typically in the morning when temperatures are moderate and wind is calm.

Step 3: Prepare the area before you unleash the product. Clear the area of debris and, if possible, mow or trim tall weeds to increase herbicide contact.

Step 4: Mix the product properly by shaking aggressively. If the weed killer is a concentrate, dilute it according to the manufacturer’s directions.

Step 5: Use the right equipment. A sprayer with an adjustable nozzle will help you apply the herbicide evenly.
