Homemade Weed Killer Recipes & Tips
30 Comments 
Pulling weeds by hand is not always easy or practical, they’re pesky and determined to pop back up and spread in no time. If you’re looking for more natural ways to control them that don’t include harsh chemicals and are safer for children and pets (bonus: most are pretty frugal too), here is a list of diy recipes and solutions from my collection. I’ve also included a few tips at the bottom.
- Vinegar: Kill weeds dead with a good shot of vinegar. For best results, don’t dilute with water and choose a time to spray when there’s no sign of rain. Household vinegar is around 5% acetic acid concentration which will do the trick for new growth. If you can find a stronger vinegar (like pickling which is about 9%), that will give better results for more mature (and stubborn) varieties.
- Salt: This is effective but keep in mind that significant amounts will cause damage to surrounding soil as well. Salt should only be used in places where you want no plant growth (like driveways, sidewalk cracks, underneath decks and patio blocks, around the foundation of the house, etc.). To use, a ratio of 1 part salt to 2 parts water should do it. You can also drizzle straight salt over top.
- Salt & Vinegar Recipe: (read note above first). Combine 1 1/4 cups of table salt with 1 gallon of household vinegar. Spray where needed.
- Vinegar & Dish Detergent: Fill a spray bottle with pickling vinegar and add a squirt or two of liquid dish detergent. Spray during the hottest part of the day.
- Liquid Dish Detergent: Make a soap solution of 1 part liquid dish detergent to 10 parts water. Soak the pesky growth with this mix.
- Boiling Water: Plug in the kettle, bring it to a boil then pour the hot water over weeds (you’re basically cooking them to death).
- Lemon Juice: Either use straight lemon juice or try 1/2 cup lemon juice mixed with 1 quart household vinegar. This works much the same way as straight vinegar, but lemon juice is more expensive. I would only use this if I had more lemon juice on hand than I knew what to do with.
- Common Recipe: 1 quart household vinegar, 1/4 cup salt, 2 teaspoons liquid dish detergent (only use a detergent that contains no bleach). Mix together and spray.
- Corn Gluten Meal (this is different than corn meal): This is an all natural product that deters weeds spreading by seed, a great source of info regarding this method can be found here: City Of Ottawa (how and when to apply it, etc.). Effective on crabgrass, dandelions, curly dock, knotweed, lambs quarters, pigweed, plantain and others. Can be used on lawns, flowerbeds, bulb beds and vegetable gardens. Make sure to use CGM that is labeled as “pre-emergent herbicide“, stuff from the feedstore doesn’t have enough protein to work. Keep in mind that using CGM affects seed growth for all types of plants, not just those you’re trying to get rid of.
Tips
- Many natural remedies and products will not only work, but they may also kill surrounding grass, plants and flowers. When using a recipe, make sure to apply to the weed only (keep in mind that liquids will saturate and seep into the ground where roots from favored plants may be able to reach).
- Use when there’s no sign of rain for at least a day or two, hot sunny weather will give you best results.
- For gardens and flower beds, consider laying newspapers and mulch in and around your plants–the weeds will have a difficult time rooting and spreading (see tip #9: 12 Ways To Reuse Newspaper Around The House).
- Weed growth is greatly reduced when using the “No Dig” method of gardening (see Diggin It: No Dig Gardening). The idea is to make a foundation of compost/mulch then only use soil where you plant (make a hole in the mulch, stick a handful or two of dirt inside then plant the seedling).
Did you know: Many weeds are used in home remedies for all sorts of things and some are even edible and tasty! For example, dandelions can be used to make a delicious syrup, wine or jelly, while plantains can be crushed and used to reduce itching from mosquito bites or relieve pain from bee stings. Take some time to research the ones in your area and you may find some pretty clever ways to make them useful–you may just decide to let a few live and flourish in certain parts of your yard

great tip for weeds! live in the Pacific Northwest and weeds abound here! I personally have more than I know what to do with. the way I tackled them before was to pick them as I saw them (I lived in Southern California) and I ended up with a weed free yard! here not everyone takes care of their yards and, of course, weeds have seeds and they blow around … I’m going to try the vinegar and salt for all the ones on the drive and see what happens!
thanks again for all the tips you send out! love this site!
Inquiry…..
With the tips published in this article, (well hopfully some of them) will they wok here in Alberta, Canada?
Thanks
I don’t see why not Ricardo…they should effective regardless of the location.
HI There, if I use the vinegar/salt/dishsoap combo, when could I grow something in that area? I will not be planting my overgrown garden at all till next spring, it’s packed with scottish thistle (let it take over 2 years ago). So, if I spray it this year, can I plant veggies next year, or would it destroy the soil for planting again?
Thanks
Salt will destroy the soil for several years. When I was a teen I sprayed a little salt water on a huge slug next to the grass and for a few years we had a bald spot right next to the drive where the salt must have run off into the grass. I would only use the salt in areas that you don’t want ANYTHING to grow.
Will this work for med size to full grown weed’s as well… And as for grass that keep’s grown and coming up through the plastic tarp of the ground…. Please help me…
A neighbour has bamboo growing in her lawn , from next door, it has grown into her tile bed. It has stopped water from draining, iced up tank, What can be done to get rid of it. It has to be strong mixure. Even if they have to get a permit to use it. PLEASE HELP
I don’t know how to kill the bamboo but I did see on TV that the roots are very invasive and need to be contained.
I had a neighbor who had bamboo in her yard. She ended up pouring straight vinegar on the main bush. It worked! Wow, it really worked. Try it. It is cheap.
About the only way to kill bamboo is to cut them down, wait for new growth to appear and treat the new growth with Baking Powder. Wet the new growth, put some Baking Powder in some cheese cloth or womens hosiery and dust the new growth with the Baking Powder. Repeat process if necessary.
I have ground ivy that is out of control. Whats a good killer for that, and if I use it am I able to plant in that area? It’s in my garden, coming through the fence from neighbors yard!
Will the vinegar affect other plants like flowers or shrubs?
Vinegar is non-selective..It will kill all plants to the ground. Draw back is it doesn’t kill the root system effectively unless used repeatedly until no new growth appears anymore. After effective treatment, the ph level of the soil needs to be adjusted.
Dandelion milk from the stems of the flower can be used to get rid of pesky warts. Apply a few times a day, for as long as it takes, if its a small one maybe as soon as a week or so. It will turn the wart and surrounding skin black, I’m not sure why, but it will get rid of the wart, pain free.
And its MUCH cheaper than the store bought stuff.
Anyone know of an organic way to get rid of 4 o’clocks that are taking over my world?
Mature Four O’clocks can easily be pulled up. Make sure the tuber is intact on the plant. To get rid of the seedlings, 1tsp Dawn liquid dish soap to 1 gallon vinegar. Spray on existing plants early evening while there is still some daylight left. This way the “broth” will have more time for the plant to absorb it. A second application may be necessary in 3-5 days.
I also find boiling the kettle and poring on the weeds kills them as well they can’t handle the extreme heat.
I read that borax kills quack grass, Will floweers vegetables and regular grass grow in the area you put the borax Also how do use the boxax? Do you put it on dry? thank you
I’ve used borax on creeping charlie, by sprinkling the lawn, lightly, so the borax will attach to the leaves. Then I just walked thru the yard, and threw out a light sprinkling, with my hands. It effectively killed the creeping charlie, without harming the lawn.
I plan to give it a shot on the quack grass, and will let you know if it works. Please let me know if you find something that works.
Thanks,
Sharon
I have used the vinegar-soap-salt solution for 3 months on my gravel driveway. It isn’t 100% effective, so there are always..still..spots of weeds that keep coming up all over. I’ve done multiple sprayings and the results are still spotty and disappointing. I really don’t want to go back to harsh chemicals. the ration I use is 2 gallons of vinegar, 1 C soap, 1C salt..should I increase the salt?

Hi Beverly, you pretty much have to dig it up and dispose of it (then pour salt and water or vinegar over the soil it was growing). I have basic details at the bottom of this page: Poison Ivy Remedies
How do I get rid of crab grass (creeping Charlie) in my grass, without killing my grass?? I have tried fertilizing, round up, and pulling them. Now I am becoming more environmentally friendly and conscious, and really don’t want to use the harsh chemicals. Please help!!!!!
Thanks.
Becky
I made a test with boiling water on one patch and another patch a sprinkling of baking soda. The boiling water worked but killed the grass. Still too early to see if the grass will come back. The baking soda killed Creeping Charlie (it turned black even to the root) but some of the grass is still ok. As with the boiling water still too early to see if the test worked. I have pets and am trying to go as eco friendly as I can.
Would you just use regular household table salt? And what would you recomend for weeds without killing the grass?
Thanks Wendy
Will the vinegar and salt mixture kill the Cameleon plant. And when could I replant in the same area?
