Organic Herbicides (Weed Killer)
Many homeowners want “organic” choices when it comes to selecting weed killers. Fortunately, there are several choices for both selective and non-selective weed control.
Vinegar has been touted as a herbicide but the kitchen version is too weak to do much damage. Industrial acetic acid will kill weeds but I consider it too dangerous to recommend.
