I have used the same method for many years now. Who would know that a huge mistake could turn out to be something useful years later? Maybe many ideas come to use that way, this one for sure did.
We were boiling shrimp with some friends when I lived in Louisiana. Being young and trying not to show it, actually taught me two things in the same weekend. One: do not put shrimp down the garbage disposal. Two: the hot mixture of spices kills your grass almost instantly! I do pretty much everything I can organically. If I still lived in the South where you boil shrimp or crawfish often, I would just use the left over water to pour on all my weeds. Since I have moved from there, now I make a special "brew" to kill all of those weeds, without hurting the environment. The ones that come up through cracks in driveway or close to the steps can't hide from this hot and spicy weed killer.
You take Cajun pepper (red pepper will do) and hot sauce, vinegar can also be added if you have extra. Bring it to a boil and pour directly on any area where you want everything to die. Be very careful not to get it on grass you want to stay alive. Anything this hot mixture is put on will die (ants don't like it either). If you make more then you use at any given time, put in bottle for next time. This works cool, but I have found it works faster when boiled, steaming hot. If you aren't wanting to see results immediately, know it works after mixture has cooled off.
I add a half jar of Cajun or red pepper and half a bottle of hot sauce to a large pot of water. You just know it is ready when your eyes are watering and the room fills with the smell of the mixture. I have added left over pickle juice, vinegar, even jalapeno juice to this, depending what is left over in my fridge or cabinets. This works and works well without hurting anything in the air; animals tend not to eat in that area but it doesn't hurt them.
If you do boil shrimp, crab or crawfish, please drain the water where any unwanted weeds are so you get double use out of something you would just throw away. At most markets that sell seafood, they have bags with seasoning already in it. I always ask this time of the year to let me know if any are past the selling date. A couple of times I got lucky and was able to get the boil in bag seasoning for a dollar. Any of these ingredients can be found at the Dollar Store. With no more worries about pulling weeds, maybe you will have more time to enjoy this beautiful time of the year.

Here is an easy all natural weed and grass killer that works fast, doesn't harm the environment and is a lot cheaper than the toxic weed killers available at the home improvement store.
I was tired of using harmful chemicals to keep weeds and grass under control in my yard. So I decided to try something new. I know that salt will kill off just about any vegetation in large quantities, so I figured it would be good for killing weeds and grasses in smaller amounts. Vinegar affects the PH of the soil also and makes it difficult for plants to grow.
So I mixed the 2 together and put them in my trusty weed sprayer to see what happened. I used a whole gallon of white vinegar and about a half cup of salt, here are the results.
I chose a test area that had some grass growing up in seams of the driveway. Here you can see the test area I used to apply the mixture.
This is what it looked like after 24 hours.
This is what it looked like after 48 hours.
As you can see it is a very effective weed and grass killer. I also tried it on dandelions and some other weeds around the yard. It worked equally well with them, but it will also kill the grass surrounding the weed if you are not very careful with the application. This year, I am going to give my kids little paint brushes with cups of vinegar and salt and let them apply the mixture to the dandelions in the grass. I think this will be an effective method of applying the weed killer without killing the surrounding vegetation. Plus, it will be kind of fun for them.
It rained the next day and I thought the grass might perk up, but the weeds and grass continued to die off. It was very effective on the broad leaf weeds. Some of the grass in the driveway and sidewalk needed a second dose after about a week, but the areas I doused really well the first time died off completely. I believe the reason for needing to reapply was because I did not put enough on those areas the first time around.

To get rid of dandelions, spray straight vinegar into the center of each plant and in about two weeks they will all be dead and gone. Any that haven't disappeared will be dead and can be dug/pulled out. (There shouldn't be any). This really worked for me and they have never grown back in the area I treated. ONLY in the center of the plant, not on the grass.

One can just pour hot water on plants to get rid of weeds. But, I wish people would really look at all the plants growing in their yards and ask why.
Plants like dandelions have deep tap roots. They break up the soil and bring minerals up to the top soil. Why not just mow them down after they've bloomed. They are pretty. Plants tell you a lot about the condition of your land.
We've been taught to prefer manicured, scrubbed yards. There are no fruit trees anymore which could have something to do with the bee problem. No berry bushes, and a few set apart plants. Why not go crazy and go for lush? Weeds would get crowded out.
Use 10% vinegar per gallon of water. Add 2-4 oz orange oil (citrus Orange oil) and 1 Tablespoon liquid soap (not germacide type but real soap).
and if you have a really bad weed problem:
Use 2 cups dried molasses, 2 cups sugar with 1 Tbsp chili pepper and 2 Tbsp garlic powder - mix it and lay around base of weeds.
You can mix the dried mix with orange oil and 1 cup vinegar but be sure you are outside as it is bad to breathe. Be sure not to get it on you when spraying and not in your eyes at all.
To kill dandelions, pour vodka into spray bottle and spray on dandelions on a sunny day. Add a little dish liquid for more stubborn weeds.

Put straight vinegar into a cheap garden sprayer ($12) and spray this onto your weeds. You can also pour the vinegar right on to the soil to kill the roots and stop everything from growing there in the future. If you heat Vinegar up, it works even better. You can also buy a special vinegar with a stronger acid content at most plant nurseries that works even better!
If you want a temporary week killer and don't want to stop everything from growing, just pour boiling water on to the area. It's easiest to use a propane camping stove and boil your water outside. Use a camping coffee pot with a handle and a pouring-spout if you have one. Be careful that the steam doesn't splash back and scald you!
Instead of using harsh chemicals that can be lethal to children and animals and quite expensive, grab a nice big pot and fill it with water. Bring water to a rapid boil and pour on weeds. This literally fries the roots and the active growing weeds nearly instantly.
By kelli H. 
Use pickling vinegar instead of regular white or malt vinegar since it contains 7% acetic acid and not the usual 5%. The ratio of 1 teaspoon (5 millilitres) of liquid washing soap to 1 gallon (4 Litres) pickling vinegar is fine.
We've used vinegar for killing weeds around the garden, for several years now. It's a great way to get rid of weeds in cracks in cement or in a paved driveway. You can pour it on directly from the jug or put it in a spray bottle (use full strength). Just a word of warning, if you don't want it to die, then don't go near it with the vinegar. If using in a flower garden, be careful around the plants you want to keep. The vinegar will leach to the other plants through the roots and kill them, so it may be better to pull these by hand.
Hope this helps! Good luck!
I feed all of our wildlife here in the yard. I have a feeder for peanuts for the squirrels, they make a mess with the peanut shells, so I got the bright idea of using them for weed control. I put them around the flowers, and have started using them around my vegetable plants. No more weeds, and helps keep soil warm, and takes less watering as they keep the soil from drying out!

We would like to try the solution of vinegar, Epsom salt, and dish soap, but are concerned if it will kill everything. We do not want "volunteers" oaks, coffeeberry, etc. to be killed. Thanks!

First of all, you'd use regular salt; epsom salt is actually a plant food. Vinegar will render the soil sterile, meaning that nothing at all will grow there, maybe for decades (it stays in the soil). It will also render the soil sterile if a rain washes it to another place. It is best NOT to use it if you ever want anything to grow, ever. And yes, it will kill "volunteers." Just lightly spray the leaves with soapy (blue dawn dishwash soap) water on a really sunny day or use boiling water.

I've misplaced a very effective recipe for an natural weed killer. It used Pine Sol as one of the ingredients. Would greatly appreciate if anyone is familiar with this recipe.
By Tina H.06/19/2013
I use white vinegar, the cheaper the brand the better. Save the pinesol mixes to spray your trash cans, theones you put out for pick up. The pine sol smell makes the trash less nasty to your nose and totally nasty to the critters like racoons and skunks who may be in search of a free meal.
Be Careful with the vinegar. Don't get it on any plants you want to keep. Otherwise it's totally safe for you, your pets, and the environment.

I believe corn bran is now used to kill weeds, used like mulch. Covering grass with a mat, boards, or black plastic will kill it. How much grass influences the choice.
How do I make and use vinegar weed killer?
By Glenda from Winfield, MO
By Janet 04/16/2010
I used it when I lived in Louisiana & had fairly good luck. On a bright sunny day, I would spray full strength white vinegar on weeds & grass growing in places I didn't want it growing (like a small crack I had in the driveway). It took a few days to work. It won't work on huge patches, just strays and small clumps.
If you spray vinegar ''at what rate?" will you be able to grow other plants in the same area? Does the vinegar sterilize the ground or how long will it keep weeds from reappearing?
Vinegar is a great weed killer, even better with dishsoap in it (the soap acts like a bonding agent) It will kill anything.
But unfortunately it changes the soil so that nothing will grow there after it has been used. Bleach is better 50/50- it doesnt hurt the soil and doesn't harm the environment. It dissipates after about 12 hours.

What is the best homemade weed killer?

By Elaine 05/13/2010
Vinegar works or boiling water but then you will kill the good things growing around it too. If you have individual weeds you want to kill, the best thing to do is take one of those sponge paint brushes (preferably a small one) and dip it in Roundup and "paint" the leaves of the weed. It takes it down to the root and does not affect the grass around it. It is time consuming but it works.

By Cyinda 04/24/2010
Vinegar or Boiling Water: Regular household Vinegar can be used or you can buy a stronger vinegar at a plant nursery. Heating the vinegar up works even better! Put the vinegar in a garden-sprayer & spray on the weeds, or pour it directly on to the soil to kill the roots.
Vinegar is more permanent & will keep most things from growing long-term, while boiling water, of course is only temporary, but it works for areas where you may want to later grow things, like weeding flower or vegetable gardens or where you may want to plant foliage or bushes at a later date.
* To boil water outside, you can use a propane camping stove, but don't leave it unattended! Not even for a second, because a child or someone's pet could get burned!
Do the environment a favor & please don't use bleach, it IS toxic!
Does anyone know where corn gluten can be purchased? I have been told it is used in Oklahoma, spread like grass seed. It apparently feeds the grass and kills the weeds.

I have a lot of grass right up next to my house and azaleas not too far from the house. Will the homemade Roundup seep over into the azaleas? I have already killed some of the grass. So far, the azalea is still alive, but I was wondering if anyone knew about this because I have more grass to kill with several more plants.

Q: How can I make my own weed killer?
Salmonfly from Rochester
There are a number of recipes for homemade weed killers. All are variations of the following recipe:
Mix thoroughly until the salt dissolves, pour into a hand-held spray bottle and spray the solution directly on the target weeds. For weeds growing out of cracks in driveways and sidewalks, some people pour salt directly on the weeds. Other people pour straight vinegar directly on weeds. Still others add a few drops of liquid dish soap to the recipe to help the solution stick to the weeds. The important thing to know about this homemade recipe is that is non-selective. Just like any weed killer, use it sparingly and with caution. Non-selective means it will kill or damage any plants or grass that come into contact with it. Also, try to avoid spraying it directly on the soil. Vinegar breaks down the soil structure and kills beneficial microorganisms. In areas where this is applied, the vinegar can render the soil sterile for several years. Other organic methods of weed control include hand-pulling, boiling water or torching.

Are there any home recipes for weed and grass killer for vegetable gardens?
Anita from Prattville, AL
By Paul A.
Fill a spray bottle with the solution and spray weeds thoroughly. The solution will kill any plant it comes in contact with. Use care to avoid over-spray to neighboring plants. Small weeds will shrivel and die within 24 hours. Repeat application if regrowth occurs from the roots.
Pour the solution directly on the roots of large weeds that have extensive root systems. Plants like burdock may take a day or two to die off. Once the root withers and becomes soft, pull the root from the soil. Be careful, good luck. (03/26/2009)
Will the vinegar and dish soap work for not just surface weeds, but roots as well? If this is not remedied soon, I will have weeds the size of trees like last year when we bought the house. That was last July, so we decided to wait. Please help, I'm desperate to sod and start a small vegetable garden. Thanks.
