The backyards on the Oakside slopes step down toward the water in short terraces, and by July every one of them smells like cut grass and tomato leaves. Diego's Landscaping NY keeps those yards on schedule — mowing at a height that holds green through a dry stretch, string trimming the awkward corners a deck can't reach, edging the walks and driveway aprons, clearing beds in spring and again in fall. On a slope the stripes take a steadier hand; done well, they follow the shape of the land instead of fighting it. It is a small kind of order, repeated weekly, and it is what makes a whole street look tended.
