That's what we do. The neighbors in question are really not into letting nature do its thing. We are in the woods, so there isn't much sun. They seem desperate to have green yards despite this, and are constantly blasting them with fertilizers and pesticides. And after all that, their yards really don't look that great anyway.

At my last house, we turned a shaded yard that was mostly dirt into a really beautiful mixed lawn through a combination of mulching leaves and sowing clover. I respect my neighbors' differing opinions on what makes an "ideal" lawn, but it would save them so much time and money if they would take a more conservative approach!
