3-Ingredient Homemade Weed Killer
Are you struggled with weeds like I do? I try to avoid weeds as much as possible, but nature will always win. So when those pesky plants show up, I make a bunch of homemade herbicides to get rid of them fast.
Plus, this herbicide is safer for pets and children!
What 3 Ingredients to Use
When you’re going to make a 3-ingredient homemade weed killer, you want to use ingredients that are known to kill vegetation but not harm humans.
Over decades of research, three common ingredients have been proven to kill weeds in the home time and time again. You’ll likely find these same ingredients in most homemade herbicide recipes:
- White Vinegar
- Epsom Salt
- Dawn liquid dish soap
Let’s try to identify, how these ingredients work as the weed killer. You know these are very random and common ingredients. But I promise, they create a team of weed killing all together. Why and how?
1. White Vinegar
Vinegar generally is an acetic acid and that acid is what kills the plant.
Horticultural vinegar works fine but it is expensive and they’re hard to find. Additionally, I have found some physical reactions using them with strong and harsh fumes.
White vinegar is a better solution which usually consists of 4-7% acetic acid and 93-96% water. Though higher acetic acid content types are available for agricultural or cleaning purposes. It is most often produced by the fermentation of grain alcohol.
Common white vinegar kills plants, so when mixed with the other two ingredients, it works more effectively.
2. Epsom Salt
Epsom salt is also known as magnesium sulfate. It is a chemical compound made up of magnesium, sulfur and oxygen. This salt really helps boost the weed killing power of this homemade weed killer.
