Homemade Eco-Friendly Weed Killer

An environmentally friendly weed killer can be made from common household products. Vinegar contains acetic acid, which is a natural weed killer and lowers the pH of the soil to prevent weeds from growing. A combination of vinegar, salt and liquid soap makes an eco-friendly solution that will destroy weeds. Saturating the soil as well as the plant itself will stop and prevent the spread of weeds. This organic formula can be reapplied as necessary.

Combine 1 gallon of white or apple cider vinegar, 1 oz. of liquid soap and 1 tbsp. of salt in an empty bucket. The acetic acid in the vinegar will kill the weeds, and the salt helps to dry up any remaining moisture. Liquid soap adds to the effectiveness of the vinegar.

Mix the solution well, and transfer desired amount into an empty plastic spray bottle.

Spray the vinegar solution directly onto weeds. Use this weed killer on a dry, sunny day to guarantee that the weed will not be receiving any moisture.

Saturate the soil with the remaining homemade weed killer to prevent future weed growth. The vinegar will kill any remaining portion of the weed, and the salt will make the soil an inhospitable environment for any plant growth.

Make Eco-friendly Weed Killer

A DIY herbicide is attractive to those who are aware of the human imprint on the environment. The harsh chemicals in commercial herbicides can contaminate soil or groundwater. Weed-and-feed combinations of fertilizer and weed killers have been used to control crabgrass and other weeds that can ruin an emerald expanse of grass. Some people add salt or mineral oil, depending upon the weed. If the roots aren’t also affected by the homemade weed killer spray, then they will more than likely create a new plant within a few days, and you’ll have to repeat the process. The acetic acid in household vinegar is concentrated at about 5 percent. The acid draws moisture from the leaves, which kills off the top growth. Stronger concentrations of vinegar for mature weeds can be found at garden centers. You may want to check the pH balance of your soil before planting healthy plants that you have previously sprayed for weeds. Vinegar and salt – Mix a gallon of white vinegar with a cup of salt and a tablespoon of liquid dish soap. It’s affordable and easy to obtain. Mix a quart of water with a tablespoon of rubbing alcohol and place it in a spray bottle. The soap is a surfactant and helps spread the acidic vinegar or salt onto the leaves of the weeds. The piping hot water will destroy healthy root systems as well, so take care that it doesn’t scorch the root systems of nearby vegetables, flowers or lawns. Gather some tools and protective wear and start pulling. Use a spade or hand-weeding tool, which looks like a thin, two-tined fork. These are good for digging out the roots that are shallow. Certain oils work well with acids such as lemon juice and vinegar. * Clove oil * Castor oil * Wintergreen oil * Cinnamon oil * Orange oil * Lemon oil These oils work well alone or in any combination. They will also make the the soil around patio paving stones on which weeds can grow smell delicious. Eco-friendly weed killers often need to be reapplied and can take weeks to truly eradicate stubborn weed growth. * Not all organic weed killers are the same. It may also be an expensive way to go the eco-friendly route with the same results as a homemade organic weed killer. The cons of commercial eco-friendly weed killers include: * Any added ingredients that change the pH balance of the soil can have negative and long-term effects, no matter how organic. * Once you have removed the weeds, keep them gone by doing a few proactive things around the garden. * Cover the entire lawn with a clear plastic sheet about 6 to 8 inches beyond the edges of the grass.


Purchase a vinegar with the highest percentage of acetic acid. Most household vinegars available have between 4 and 7 percent because of their typical use in the kitchen and for cooking purposes; any of these will work.


Selectively spot-treat problem areas with the homemade weed killer; the vinegar solution can be harmful for grass and other plants.
