It's that time in the Southwest that weeds are bursting out of the ground and I need to stay on top of them or I will be overwhelmed. My wife and I have been focusing on saving money and hesitate to spend $18 a gallon on Round-up that needs to be applied once a month and we need about 3 gallons each time to cover all of our property. I went online and found a common recipe using apple cider vinegar, salt, and Dawn. Mixed up a bunch a week ago and applied it liberally... Some weeds died while most were not affected at all... Anyone have a good recipe for homemade weed killer that works?
