Growing a gorgeous lawn and garden free from weeds is possible with this easy homemade weed killer.

Weeds love my yard and garden, and pulling them seemed like a full-time job. Therefore I decided to try my neighbor’s DIY weed killer recipe.

Easy weed control is the key to enjoying my yard, flower garden, and raised bed garden.

Weed Killer Supplies

  • White Vinegar (distilled)
  • Dawn dishwashing liquid
  • Epson salt
  • Garden sprayer

 

🌸 I recommend you watch this video of me making homemade weed killer.

This recipe uses the acid in the vinegar to wilt and ultimately kill weeds. It is not harmful to the environment like store-bought weed killers.

1. Measure Weed Killer Ingredients 

You can use a clean bucket or garden sprayer to mix your solution. 

I purchased a new garden sprayer and labeled it so that I would not mistakenly use it for fertilizing my plants.

First, I added two cups of plain Epsom salt to the garden sprayer.

Adding the dishwashing liquid to the garden sprayer

Add dish soap

Then I added 1/4 cup of Dawn dishwashing liquid (the blue one) into the sprayer.

Next, I added the white vinegar to the fill line on the sprayer. 

Note: If you use a one-gallon sprayer, you cannot add the entire gallon of vinegar. However, you can add the remaining vinegar after using some weed solutions. 

 

2. Mix Weed Killer Solution

Since I used a new sprayer, I had to insert the sprayer nozzle tube and screw it in place.

Next, I inserted the pumper handle and tightened it in place.

3. Apply Weed Killer

Before applying the solution, I had to use the handle to pump air into the sprayer to create pressure. 

Note: You will need to repeat this process when the sprayer loses pressure. 

Next, apply the week killer directly to the weed you want to eliminate, then check back in 24 hours to see the results.

This solution will wilt the green growth, but it does not kill the root system. Therefore, you may need to reapply if more growth reappears. 

Note: For the best results use this solution on a sunny day.

Another way to kill weeds is to pour boiling water over them. However, this method is very time-consuming.

I have been using this for years, BUT you better not get it on metal fence, mail box post or metal outdoor furniture. It will eat a hole in it the first time.
