I was given this recipe for an Organic weed killer. My husband has a nursery so we need to keep weeds down, but my chickens run the area every day so I don't want a lot of poisons around. I tried this on the weeds along the walkway and honestly, they were all brown and crispy the next morning. 1/2 gallon of apple cider vinegar 1/4 cup salt 1/2 tsp Dawn dish soap. Just put it in a spray bottle and spritz away at the individiual weeds. Amazing!
