Hello to all. I have a garden that I do every summer but it always gets overtaking by weeds and grass. I have tried keeping tarps and leaves on it all winter to smother it and that didn't work. I till it at the end of the season and at the begging of the season. Several weeks ago I sprayed some weed and grass killer on it (cant remember what kind) and still grass is now coming up before I even get to plant my garden. The weed killer that I sprayed was some kind of eco/pet friendly that my wife persisted on because we have livestock that might get in there, which I can understand where she is coming from. Is there something that I can make homemade that will kill my grass I weeds off in my garden? I still have a few weeks before I need to start planting so if someone has some tips that would be great. Again thanks for your time.
