Weeds are super annoying and they show up every Spring without fail (and doesn’t it seem like there’s more of the buggers every year?). Whether it’s between cracks in your driveway, in the middle of your yard, or in your vegetable garden or flower beds, weeds can pop up just about anywhere.
There are easy ways to get rid of them (think Roundup), but are chemicals such as these in the best long-term interest of your health, and the health of your kids and pets that love to play in your yard?
Fortunately with a little time and effort it’s not impossible to stay on top of weeds with an organic line of defense. But if pulling them out manually takes too much time or using mulch or a ground covering is too resource or cost-prohibitive, you can consider a natural weed killing solution that is easy to make in the comfort of your own home.
I will say I recommend using this only for pesky, hard to get at weeds since the spray will kill your other plants too, so not ideal for your flower beds or vegetable patch.

The reason I don’t encourage using this spray as your only line of defense, is that over time it can adversely affect the overall levels of salinity (salt) in your soil. That can make it difficult to grow plants down the road, and it may take several seasons and lots of rainfall to reduce saline levels back to normal. Therefore I really recommend using this solution sparingly and in areas where you’re not counting on other plants to grow.
A thick layer of mulch can not only look aesthetically pleasing, but it can also keep weeds at bay. How is this possible? A thick layer of mulch, or a ground covering (such as this one by Dewitt) will keep out sunlight. Weeds are just like any other plant – they need sunshine and water (think photosynthesis) to grow.
Here’s a list of supplies you’ll need to make your homegrown weed killing solution. If you don’t already have these lying around, you can obtain most of these at your local grocery or general store, as well as online.
- Spray Bottles 4 to 16 oz bottles (Mist, Stream and Off settings, funnel, caps and labels included) –
- Epsom Salt – for 5 lbs (Made in USA and GMO free)
- Salt for 2 – 26 oz containers
- Dish Soap
- Apple Cider Vinegar for 2 – 16 oz bottles
- White Vinegar for 1 gallon
- Corn Gluten Meal for 40 lbs
Unfortunately there’s plenty of hype around using horticultural vinegar on your weeds, because it is very successful at killing them. But it can also cause harm to animals and the environment when used in large quantities or concentrations (in concentrations above 11% acetic acid, vinegar can burn skin and cause damage to your eyes. Concentrations above 20% are corrosive to tin, aluminum, iron, and concrete and can even cause blindness).
Get your supplies ready, here’s some easy recipes you can use as a base for your home-made weed killing solution.
For optimal results, you’ll want to apply these solutions during the sunniest time of day, and spray directly onto the weed, trying best to avoid the areas around the weed.
Vinegar, Dawn And Salt
This is weed killing in its simplest form, with salt, vinegar, and dish soap. Combine the following ingredients in a spray bottle:
- 1 gallon white vinegar (household/distilled)
- 1 cup salt
- 1 Tablespoon liquid dish soap

This solution works particularly well on dandelions. When applying, set your spray bottle to the “stream” (direct shot, not mist) setting if possible and spray directly onto the dandelion heads. This should help take out the dandelions without affecting the grass too much.
Before you spray them all down, especially if it’s early Spring, note that dandelions are an important food source for pollinators.
“Flowers are an important food source for pollinators — especially bees,” John Mulseed wrote in his Greenspace column. Dandelions are one of the first flowing plants and provide both pollen and nectar. By late May, more flowering plants are available as food sources for bees and other insects, so they don’t have to rely as much on dandelions.
Apple Cider Vinegar And Epsom Salt (With Video)
Don’t have white vinegar but have some apple cider vinegar (ACV) laying around? Good news, this recipe uses ACV instead of white vinegar, and doesn’t need dish soap.
- 2 cups of apple cider vinegar
- 1/2 cup of Epsom salt
First fill your spray bottle with the ACV, then sprinkle the salt in (we recommend using a funnel to avoid spillage) and shake it up well before using.

For Younger Weeds And Sidewalk Cracks
For weed treatment on larger surface areas like your patio, a bed of mulch, driveway, etc. we recommend using a diluted solution. It works just as well but won’t be as corrosive to the environment you’re spraying in.
- 1 pot of water
- 1 Tablespoon of salt
Get the water up to a boil in a pot, then add the tablespoon of salt. You’ll want to pour this on your offending weeds while the solution is still hot, and should see results almost immediately.
Is There Homemade Weed Killer That’s Safe For Grass?
As we noted the vinegar and salt in the recipes above can affect soil salinity and can be tough on grass. So if you’re already struggling to get your lawn to turn nice and green, here are some modified recipes optimized for weeds in lawns.
Corn Gluten Meal
For this to work, you’ll first need to remove existing weeds by manually pulling them. Next, sprinkle corn gluten meal on your lawn. Why does this work? It suppresses the development of feeder roots in weeds such as dandelions, crabgrass, plantain, curly dock, pigweed, knotweed, lamb’s quarters, and more.
Soap And Water
This method dries out the weeds. Create a water/soap mixture with a 10:1 water/soap ratio (10 parts water, one part soap). In the middle of the day when the temperature is the highest, spray this mixture on the weeds. How does it work? The soap helps the solution stick to the weeds, and when the water evaporate in the heat, it will dry the weeds out.
