DIY weed killer is easy to make, and this natural mixture is safe around kids and pets. This homemade weed killer spray even works on tough weeds like bermuda grass and nutgrass.

If I told you that the 3-year-old and I spent an hour yesterday spraying all the weeds in our yard, you'd probably have a conniption fit.

"You WHAT? Those weed killers are full of terrible chemicals! I can't believe you even have those in your house. And you let the KIDS use them? The horror!"

(My mom is probably dialing my number right now to Discuss My Parenting Choices.)

Yes, mom, it's true. I even let her use the sprayer. And I wasn't worried about it in the slightest.

How is this possible?

Simple! Since we make lots of our own natural products, like  kitchen cleaner, insect repellent, and air freshener sprays, I have lots of experience in making natural substitutes for toxic products. Using homemade, natural products means it's safe for the kids to help in the house and in the garden.

That said: it's easy to make a natural weed killer spray for the weeds in your sidewalk and driveway. It even works on obnoxious weeds like bermuda grass and nutgrass!

And I'll bet you have all the ingredients in your pantry right now. Let's do this!

DIY Weed Killer

Ingredients

2 cups white vinegar

1 Tablespoon table salt

1.5 teaspoons dish soap

Instructions

Combine all ingredients in a 16 oz. spray bottle and label the bottle.

Spray on weeds, thoroughly saturating the leaves. Within 24 hours, the plants will wilt--and they'll be completely dead in 48 hours.

Important! I only use this mixture on weeds in the sidewalk and between my raised beds. This combo is a non-selective weedkiller.

It will kill any plant that it touches, and if the salt gets into your garden soil you'll never get anything to grow there again. Remember the story of the Romans sowing the Carthaginian fields with salt after sacking the city? Yup, just like that.

    This worked beautifully for me for the weeds that grow up between the cracks in the sidewalk. I had to really soak them to make sure it gets not just the plant but the roots…but it’s been a year and they never came back

    Straight vinegar has worked for me on poison oak. Of course some hardy weeds are going to come back.

    You might try adding a little cooking oil, it helps the vinegar to cling to the plant leaves. But it takes a few sprayings over a week or two

    It is also my experience that even straight 20 percent vinegar doesn’t phase Bermuda grass. I can hardly imagine choosing to essentially add salt to soil.

    Sorry, but doesn’t work, it works on small things like just growing weeds but the big ones and other weeds it just makes them look brown

  6. Daniela on October 16, 2015 at 2:13 pm

    this is totally bad for the soil. and here, if its forbidden to do so, so dont get caught

    I’m sorry, but this vinegar mixture simply does not work. Yes, I used the Apple Cider Vin, I was so disappointed as I really wanted to kill my weeds naturally. :):)

    Thanks for the interesting tip. I am going to try it on my sidewalk.
