I’m not too thrilled about spraying any type of chemical where my son plays, and certainly not one that has accusations of cancer flying around. Of course, I also REALLY don’t like weeding.

How to Make Homemade Weed Killer



  1. Mix the vinegar, Sal Suds, and Epsom salt in the pump sprayer until the salt has completely dissolved.
  2. Spray the mixture on the weeds in the morning after any dew has dried.
  3. Allow the combination of the afternoon sun and homemade weed killer to kill the weeds.

The Results

So let’s take a look at this homemade weed killer in action. Here is a small area beside my house where weeds just love to pop up.

A Few Important Notes

Vinegar and Epsom salt are desiccants, meaning they’re able to draw moisture from other items. Sal Suds breaks up the waxy surface on weed leaves and makes it easier for the vinegar and Epsom salt to soak in.

When these three ingredients combine, they make a powerful and natural weed killer that draws moisture from the weed and causes it to die.

However, it’s important to keep in mind that this weed killer can’t tell the difference between a weed and a good plant. Therefore, when you’re spraying the weed killer, make sure you don’t accidentally spray anything you want to keep, such as these fast-growing vegetable plants for a quick harvest.
