Get rid of sidewalk weeds with the help of baking soda or vinegar.

Weeds are irritating plants that can appear outside your home in your yard, garden or even in the cracks of sidewalks. Although killing these unsightly growths with pesticides can work, pesticides can leave behind chemicals that are harmful to other plant life or animals that come into contact with it. Using natural remedies like baking soda or vinegar can be a much more eco-friendly and equally effective way to free your property of weeds.

Baking Soda

Use baking soda on weeds to destroy them within a few days. Pour baking soda over the weeds and let sit and repeat once a day until weeds are gone. Use baking soda to prevent weeds from regrowing by dusting areas where weeds frequent with the powder once a week, or twice for aggressive weed growths.


Vinegar has a lot of acidity, which is a weed's worst enemy. Make a spray out of vinegar and spray weeds with it once a day until they recede and die. Another idea which works for weeds growing out of small cracks is to pour the vinegar into the cracks and let it soak down in them. Use white distilled vinegar or raw apple cider vinegar, both of which you can find at health food stores.

Vinegar and Baking Soda Spray

A spray made of vinegar and baking soda is another effective method for killing weeds. Use one part baking soda and two parts vinegar. Pour baking soda into the spray bottle first, then add vinegar. The mixture will bubble up for a minute, but once it's done you can screw on the nozzle, shake it, and spray the weeded area. Spray weeds daily until gone and keep on hand should you see any small weeds start to grow. Alternatively, sprinkle baking soda over weeds then spray them with vinegar.

Vinegar and Baking Soda Paste

A paste of baking soda and vinegar can be applied to weeds and works well for weeds that are deep inside sidewalk cracks. Mix two parts baking soda with one part vinegar in a bowl. Use a large bowl so the mixture doesn't bubble over the edge. Once the bubbling has stopped, stir, then fill cracks with the paste or apply it to the base of weeds. Apply every two days until weeds are gone, then rinse away any remaining paste with your garden hose.
