Dandelions are a nuisance, but they are also recognized as one of the most pragmatic plants on earth. That's right. From the base of its long tap root to the top of its jagged leaves, this plant has long been a source of medicine and food. Wine, tea, and herbal medicine top the list of "things to do with dandelions" - all of which need to be done with plants free of herbicides and other chemicals. But the big question remains, how do we rid our lawns of these yellow intruders? The same way you harvest them for food and medicine. Pull them out by the roots.
