Simple Easy to Make Weed Killer.



15 Bytesize articles instead of a trilogy in one post.

I had a real weed problem in the front yard and bed. The home owners assn threatened bloody murder if I did not take care of it. I searched the web and found a weed killer that puts the commercial stuff to shame and it is a lot safer on the environment. I have not had to weed in several months. It is probably time for a second application this year.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Ingredients.

1 gallon or thereabouts of the cheapest vinegar. s/b under 2 dollars.
1 container table salt. s/b under 50 cents.
 2 tablespoons liquid detergent for washing dishes or such.  whole bottle should be under a dollar.
Extra container the size of the vinegar container.

1 sprayer unless you want to splash it out manually.

Step 2:

Into the extra empty bottle put 2 tbls of the soap. Add 1/2 or about 1 cup of salt into the extra bottle. Add about 1/2 or so of the vinegar into the other bottle. Cover the other bottle and shake to mix the ingredients. Lastly add the rest of the vinegar into the other bottle. recover again a shake slightly. Pour into sprayer container and use the sprayer as the manual recommends. Go around and spray where weeds are or will be. You will see weeds start dying within hours. This concoction puts the commercial stuff to shame. I like to use it around the a/c with a heavy dose. One good thing as it really does not seem to affect the grass.

Step 3: Try It You Will Like It.

It's that simple. Let me know how it works for you!

    Killed a few small broad leaf plants, but they grew back after 2 weeks. The smaller leaf plants it did nothing and the tall weeds in the back, same thing nothing. Back to roundup for me.

    So, a lot of vinegar, a lot of salt, splash of dish soap.

    I am removing weeds from a concrete area that was formerly used as a skate park. A new fancy park was built and this one was abandoned, but perfect for ball hockey... so time to salt the earth (and vinegar, with a splash of detergent). The longer (ie never) it takes the weeds to come back the better.

    I love the idea of using non-toxic solutions but, the table salt will sterilize the ground for what will seem like "forever". Substitute the table salt with Epsom salt which does not contain sodium chloride. The vinegar and soap will still be effective without sterilizing the soil. Props to…

    How well does this work using on poison oaks, ivys, etc.?
    Also, will it hurt Holly shrubs to use around it?

    This is so great and I don't have to worry about the pets getting on it!!

    This will be great for my gravel-covered parking area which always has weeds popping through. No need to worry about the effect the salt has, either. Thanks for this. Now to convert to litres, grams, etc. :-)

    Thankx for the comments. if you go to a search engine and tpe in say 1 litre =, you can easily get your answer. Works with at least Google.

    Thank you for your comment. I am sure you are right. but after several months I need to do a re-application. It does not bother the grass we have here at all. As for a flour or vegetable garden, I would not use the salt there either. Where there are only bushes or trees, I have no problem with it.

    I wouldnt recommend using the salt in any area you want anything to grow as it builds up in the soil, takes forever to disapate and will kill almost anything planted. That being said.... Ive used vinager and a little dish detergent for yrs to control all but the most stubborn weeds. it works best if applied early in the day and be sure to soak the base of the weed
