New Trier Township is stitched with ravines — old wooded creases that fold downhill toward Lake Michigan, holding shade and cool air even in May. Green Earth Lawncare LLC works the lawns above and around them, where oak canopy, slope and lake air all have opinions about how grass behaves. Mowing, trimming, edging, bed maintenance and spring and fall cleanups keep those yards even and open under heavy old trees. In early spring, when the oaks are still bare and the light comes all the way down to the ground, the first true cut of the year makes a lawn look brand new. Nothing fancy about it; it just looks right, and it looks right from the sidewalk.
