Natural Weed Killers

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.

Yes, vinegar will work as an herbicide. Be very careful not to get it on any plants that you want to keep, it will kill them as well. It is not a pre-emergent herbicide, so you will have to re-spray to get new weed plants, but it is somewhat easier on the environment.

My neighbor has weeds that are so high that they are starting to cover my fence. I have two big dogs and don't want them sick. Can you give me a recipe for a good, safe weed killer?



Natural Weed Killer Recipe

  • 2 squirts liquid dish detergent
  • 1 gallon vinegar
  • 1 lb. salt

Stir salt in just enough water to dissolve. Add rest of ingredients after the salt dissolves or the salt will clog your sprayer. Also, do not spray this mixture anywhere that you might want to grow anything in the future.

You need to boil that down to concentrate it. Regular store bought vinegar is diluted way too much and you might as well fertilize your driveway. That recipe seems to activate dormant weed seeds. It sure did on my driveway.

Simmer that mixture on an outside barbecue, otherwise the vinegar smell can get strong enough to bother you.

To make that mixture effective, you need to simmer it down to half the volume. Have FUN!

Natural Weed Killer Recipe

To kill moss, take dolomite lime or baking soda and spread over the moss. Lime you can get at the gardening store. You can get large bags or boxes of baking soda (sodium bicarbonate) at Costco or Sam's Club. Take small shovelfuls or a garden spreader and sprinkle it over the moss. It will kill it. Then wait a day and sweep it off. Baking soda will also kill grass and weeds because it is highly alkaline as will lime if you use too much.

The following recipe is at base 2 forms of acid so if you really soak the ground well nothing will grow for months. Be carefull you only spray what you want to kill.

Put 4 oz lemon juice in 1 quart spray bottle. Fill to top with white vinegar (10%-20% acididity is best). Shake well. (04/02/2005)

How much do I need to cover 17,000 square feet. Are you really looking at using 1 gallon of vinegar? How long should I wait until I try to put down grass seed to grow grass?

I have experimented on some of the ways suggested in other gardening sites and vinegar can cause fungi growth in colder regions, though being the most damaging out of the solutions I tested. Salt is the best, though a 20% baking soda solution was very effective and burned through my Arenaria norvegica plant. I also tried boiling water-not effective at all, and salt water-dehydration was in the first 48 hours but the plant still had a reasonably firm footing. (05/07/2006)

Pull Them Out

Whatever happened to good old-fashioned pulling them out. I know I'd rather spray half my backyard with Agent Orange, but like everyone says, 'that stuff is bad for the kids,' 'this stuff is so good, but rots a hole in the ground so big you can fall in!' I borrow my neighbour's shovel and have at all the weeds around the place. Works fine and gives you something to do outdoors. (12/13/2006)

To the man who mentioned wanting to get rid of clover... why not keep it. Many eco-friendly yards encourage clover growth, some people plant it instead of grass. It's great for putting nitrogen into the soil and doesn't need to be watered. All around better for our planet than grass. (05/16/2007)

I just mixed a spray bottle of 1 cup salt, 1 tablespoon dish soap and the rest vinegar. I then sprayed the weeds with this mixture. After that, I poured straight salt on the weeds. That night the weeds were dying. This is a great safe way to kill weeds. I used Roundup 2 years ago and my cat got sick. My dogs chew on weeds so I don't think Roundup is safe even after 24 hours.
Plus Roundup is more expensive than vinegar, salt, and dish soap. Just make sure you only do not spray or salt anywhere you don't want to kill plants or grass. They say the salt lasts longer than Roundup and results are as quick or quicker than Roundup. (08/26/2007)

Control clover in lawn by fertilising with nitrogen. Lawn grows stronger clover tends to weaken in nitrogen rich soils.
