Homemade DIY Weed Killer

Gardeners have been making weed killers from household items for hundreds of years and they work just as well. Homemade weed killers have the added advantage of being able to control precisely what’s in them as you are the one who makes them and you know what’s in them. In this article, we’ve put together 8 easy and effective weed killer recipes that you can try out at home.

1 – White Vinegar Weed Killer

In other words, you can use vinegar as a weed killer, and the main reason is that vinegar contains acetic acid, which is the main ingredient in vinegar. You should use 5% acetic acid white vinegar; even though you can get 10%, 20% and even 30% acetic acid white vinegar, these are a lot more expensive. In order to make this homemade weed killer, what are you going to need? 5% White Vinegar

How to use
Basically, you can just pour vinegar directly onto the weed or you can pour vinegar directly into a spray bottle and spray the weed directly with the vinegar. Some weeds may die off right away, while others may take 14 days before you notice a difference. If you need to reapply this weed killer, you should wait 21 days. Using apple cider vinegar won’t work.

Other Uses
There are a couple of advantages to making a mixture of vinegar and water, which can be used as a general purpose household cleaner, along with being able to get rid of common household ants (Odorous ants). Odorous ants communicate with pheromones, leaving trails of different scents, which you can disrupt with this vinegar mixture to stop them from entering your house.

CAUTION: White vinegar containing 20% and more acetic acid is considered an industrial herbicide and can cause chemical burns and blindness. So make sure you wear protective clothing.

2 – Homemade salt and vinegar weed killer recipe

There is a vinegar weed killer that I use all the time, and it also uses 5% white vinegar in its formulation. In order to make this simple three-ingredient homemade weed killer, you will need the following ingredients:

  • 1 L white vinegar
  • three large spoons of table salt
  • three large tablespoon of dish soap or washing up liquid
  • spray bottle

How to use
In a spray bottle, combine the vinegar and salt then shake it vigorously. Once the salt has dissolved add the dish soap and shake the bottle again. For best results, use it on a dry, sunny day before midday before the sun sets. 

Plants and weeds are killed indiscriminately, and your soil may become slightly acidic for a while.

CAUTION: Vinegars that contain 20% or more acetic acid are considered industrial herbicides that can cause chemical burns and even blindness.

 3 – Salt Homemade Weed Killer

Before the 1800’s Spanish and Portuguese convicted traitors would have their lands salted to prevent anything from growing, starving their families. You need two parts salt (table salt – sodium chloride) to one part water to make this salt weed killer recipe and a spray bottle.

How to use
In order for the salt solution to work, just mix the salt and water in a spray bottle, wait until it is well combined, and spray the salt solution on the weeds or area you desire. You can now sit back and watch the weeds die. It is also possible to directly spray salt on the weeds (we do not recommend this).

CAUTION: Salt can absorb through the soil easily, preventing future growth in that area, sometimes for quite awhile, so when not using it on patios, drives, or gardens, you need to dilute it with water before using it.
