DIY: Natural Weed Killer


No gardeners like weeds in their garden. But even the best of the plots can grow weeds. Why wouldn’t they? They get good soil and sunlight to prosper. Weeds choke out the plants by soaking water and nutrients from the soil. So, what’s the practice to prevent weeds from spreading in your garden? 

The best thing you can do to keep your garden weed-free is to prevent the weed from reaching the seeds. You can do this by killing them at an early stage. While many people use chemical weed killers, it’s best to use natural and homemade weed killers. After all, not only you, your pets and children will also get exposed to the harmful chemicals. Pulling out weeds using hands is always the easiest solution, but there are times when herbicides work even better. 

Here are effective formulas to create your DIY weed killer at home if you’re seeking an alternative to commercial weed killers. 


Natural Weed Killer Formula Using Vinegar And Dishwashing Soap

Things you’ll need :

  • 1 gallon of white vinegar
  • One tablespoon liquid dish soap
  • 1 cup salt

Mix these three ingredients in a spray bottle and spray it onto the weeds during the sunniest time of the day for maximum results. 

When looking for an alternative for killing weeds, these ingredients have all the properties to do the job. The acetic acid in the salt and vinegar helps to draw out moisture from the weed. On the other hand, dish soap acts as a surfactant. It helps vinegar and salt to bind together to the plant’s leaves. The salt and acetic acid dry out the leaves, leaving no room for weeds to make food, and eventually, it will die. When you do this on a sunny day, the results will be visible in just a matter of few hours, and you’ll see weeds turning brown. 

Depending on the type of weed and season, the results can vary in time. But there is a downside as well. Chemical solutions are meant to go to the roots and kill the weed completely, but this homemade formula is not decisive. The formula can’t go to the root system, so you’ll have to give multiple treatments to keep weeds at bay. 

Besides the downside, keeping the solution ready in a spray bottle is an effective and affordable solution to keep weeds growing along the pathways or fences. Ensure you spray only on the targeted areas and never near the plant as it can harm the nearby plants. The vinegar doesn’t know the difference between friend and foe, right!

Driveway And Concrete Weed Killer With Salt

Things you’ll need :

  • Salt
  • 2 quarts boiling water

Gardeners have been using salt to kills weeds in sidewalks since forever. But do you know using salt with boiling water makes it a one-time good deal? You must have heard about the caution with salt to kill any plant if used with boiling water. That’s why the mixture works so well for killing weeds on the driveway and sidewalks. If you want to be more accurate, you can use a tea kettle instead of a pot to pour water exactly where it’s needed. 

Weedkiller Recipe With Borax

Borax weed killers can be used in lawns but use them carefully. Overusing borax can cause damage to the plants. For this, you’ll need :

  • 2 gallons of water
  • 1 cup powder borax

Just mix the two ingredients in a spray bottle and spray to the areas required. 

Other Ways To Treat Weeds In A Garden

There are many other ways to treat weeds in a garden, and the practice is to combine a few to keep weeds at bay. In combination with weed killer, you can try the following measures :

  • Pull them out – The traditional way to remove weed! Whenever you see a weed growing in your garden, just pull them out. 
  • Smother weeds – This tip usually helps while starting a new garden bed. You can clutter weeds and grass with plastic tarps or cardboard. Some people use plastic tarps to cover and remove them after the weeds are killed. The preferable way is carboarding, though. Just cover the weed with cardboard, put some soil over it and remove it after the weed is killed. 
  • Corn Gluten Meal – Corn gluten meal is a natural by-product of corn processing that prevents the weed from setting roots after germination. However, you have to be extra careful while using corn to prevent every plant from setting roots after germination. So, make sure you don’t spread it to the places where you’re germinating seeds. 
  • Synthetic herbicides – Of course, if you’re comfortable using synthetic herbicides in the garden, you can. But it’s recommended to avoid using them in a fruits and vegetable garden because you will eventually eat the produce.

With all the tips mentioned above, you can effectively manage weeds in the garden. The best way is to take action as soon as you see them growing. Remember, if you’re using any weed killer, safeguard your plants first, as they can also get damaged in the process. While working with any weed killer, always wear a mask and gloves and keep your children away while working.
