Midsummer mornings on the North Shore start humid and silver, mist sitting over the Skokie Lagoons before the sun burns it off the water. Superior Lawn Care. SLC is out early on those days, because grass cuts cleanest before the heat sets in and the afternoon storms build inland. Mowing, trimming, edging and regular seasonal maintenance keep New Trier Township lawns dense and level through July, when everything green is growing at full speed. Cut early, cut sharp, and by nine in the morning a yard is already done and drying in the first real sun. It is a small, precise thing to give someone — a lawn that looks finished before the day has properly begun.
