Aurora has called itself the City of Lights since it lit its streets by electricity, and the blue hour just before those lights come on is the best time to look at a lawn. Blue&Green Landscaping works into that window in spring: mowing, edging, trimming, fresh mulch laid dark against new growth, the whole yard drawn tight. The two colors in the name are only the truth of a May evening here, sky going indigo while the grass still holds its green. Cleanups in spring open the season and cleanups in fall close it. In between, the aim is a yard that looks composed every single week, not only the week it was done.
