I don't disagree that the lawn care products are toxic and long range dangerous, but, since 99% of us who have property insist on grass. And inevitably dandelions...that can be quite aggressive and one can loose the battle with them quickly....what is the alternative.....we have a veggie garden and some flower gardens, but like everyone else...much grass...that must be " maintained" to keep property values stable..........so I have a lawn service.....
