Natures Wisdom 20% Vinegar Gallon
Vinegar is a natural weed killer that has worked for centuries, and it is just as good now as it was then. The vinegar must be of a higher acidic content than regular household vinegar, and for the most eco-conscious people out there, organic vinegar is available. The acid in vinegar will kill the plant effectively, but for deep rooted species, like dandelions, two or more applications may be required. Because this is a mild acid, don't breathe in the fumes, but in every other way it is non-toxic and can be used around kids and pets.
