Late August along the upper Susquehanna is heavy and green, the river low, the bottomland grass still growing like it is June. Lemos Landscaping LLC mows through it and keeps the details tight: string trimming out to the fence line, a cut edge along the drive, fresh mulch when the beds have faded, clippings cleared off the walk. On the rises toward Guilford and Afton the yards run to slope and ledge, and each one gets mowed the way it lies. Spring cleanup opens a property up after the valley's mud weeks; the fall round takes the leaves down to bare turf before winter closes in. Steady attention, week to week, is what makes a lawn look effortless in the end.
