How to Make a Homemade Weed Killer-Recipe
You can make a natural weed killer using things easily found around your home.
For our recipe, here’s what you need to gather:
- One gallon of white vinegar.

- 2 cups of salt {regular salt}.
- A bucket.
- Spoon.
- Water-resistant gloves.
- Spray bottle.
Vinegar is the main ingredient of this recipe; it breaks down the weed cells, preventing them from functioning. The salt will dry out the weed plants, inhibiting them from growing.
On the other hand, dawn dish soap is a surfactant, lowering the mixture’s surface tension and allowing it to be absorbed into the plant instead of remaining on the surface.
Use salt sparingly because too much of it can damage the soil.
Alternatively, you can use borax but beware that it creates a potent weed killer.
You will use the bucket to mix the ingredients and the spoon to stir the liquid, ensuring it combines well, while the gloves protect your hands.
Vinegar-based homemade weed killer is excellent for getting rid of weeds on walkways, driveway cracks, pavers, sidewalks, and rocked areas, and it also comes in handy if you want to get rid of ants. However, it can kill some grasses, so avoid using it to kill weeds on lawns with grass.

How To Use Homemade Weed Killer
This easy homemade weed-killer recipe can be used to kill any plant because it is nonselective. When it comes to application, you must pick the day wisely.
For instance, avoid rainy days because the rainwater will just wash it away, rendering it useless.
Pick a sunny, dry day to apply the weed killer mixture, and make sure you spray all the weed surfaces thoroughly.
However, do not apply too much of the solution because compound or chemical plant killers in large doses will be toxic to other living organisms.
For example, vinegar and salt solution is harmful to tiny mammals and can also damage the soil microbiome; therefore, you should be careful not to spill it on the ground.
If you apply the weed killer to a sizeable solid weed patch, consider adopting a watering and soil-building strategy once the weeds are eliminated to restore the health of the soil.
If you have any leftover homemade weed killer, put it in a plastic container, cap it tightly, seal it, and keep it in a dark, cool spot for future use.
Storing this DIY weed killer is pretty easy, but keep it away from your kids and pets.

You will see the outcome in a few hours if you apply it on a sunny, warm day; you will see the weeds starting to wither and turn brown.
The downside is, unlike chemicals, homemade weed killers are not too effective on the root system, so you will need to do multiple treatments to keep weeds out of your garden.

Can You Use Epsom Salt in Homemade Weed Killer?
Yes, you can use Epsom salt to make homemade weed killer. For instance, you could mix it with vinegar to create effective weed control, but the solution is also destructive to other plants it comes into contact with.
Therefore, Epsom salt can be harmful if misused. Make sure you attentively apply a homemade weed killer made of Epsom salt to ensure it does not touch your plants.
