Guelph, in Southern Ontario, is passing a law soon, of no herbicides or pesticides for lawn care. Can anyone give me any tips as to a weedless lawn (other than get the knife out!) Is there anything that can replace the hose spray container of Killex or Weed b Gone...to spray a large lawn area? I tried the lemon juice and vinegar mixture, but it didn't work. I'd like to know what kind of "NATURAL" solutions people are using..that work for large mass grass areas! We have a lot of dandilions in this neighbourhood along with chickweed, clovers and moss. Thanks in advance for your help!
