The old oaks in the Grove have been dropping leaves on this corner of Cook County since long before there were lawns beneath them, and every Glenview October the whole village inherits the result. Hurst Landscape Company handles it — leaf cleanups in fall, the cutback and clear-out in spring, and through the warm months the steady work of mowing, edging and trimming the lines that make a yard look finished. Along the North Branch the ground stays soft and the grass keeps growing late, which means the last cut here often comes well after the neighbors have decided the year is over. A lawn ought to look like someone paid attention to the corners, not only the middle. Glenview, Northfield, Northbrook, Skokie and Wilmette.
