None of these methods will work by themselves, but some vigilance, regular control of undesirable plants and proper care for desirable plants should minimize weed growth without the need for any chemical controls.
Also consider controlling your reaction to weeds. Some homeowners and experts suggest a live-and-let-live philosophy, so to speak.
“If you look at my lawn, you would think this is my approach. It all depends on the person's wants,” Hartzler said. “My lawn has deep shade from trees, and two labs using it as their playground, so I realize it will be impossible to get a vigorous lawn, so I accept weeds. In my garden I weed enough to eliminate competition between the vegetables and weeds, but I accept a few weeds that emerge later in the season.”
