Answer: Aside from pouring boiling water on them or mowing them low before they set seeds, there are no other least toxic ways to deal with them. Dandelion plants can't be eliminated by yanking off the tops, but they are easily dug out by hand. A dandelion digger is a specialized tool that removes a wide variety of individual weeds and their roots, with little soil disturbance. The tool looks like a large screwdriver with the "business end" resembling a fish tale. It works by maneuvering it in the soil, parallel to the tap root. With a small pivot, it's easy to lift the entire plant, root and all (that's the theory at least), from its stronghold.
