West of nearly every yard in Centennial the Front Range stands up along the horizon, and on a September evening the high peaks keep the last of the light for a while after the street below has gone blue. Seasonal Vista Landscape Maintenance LLC favors that hour — the mower cooling, the cut lines running clean toward the sunset, a yard put to bed for the night. Autumn is the honest month for turf at this elevation: aerate before the ground tightens up, overseed into the holes, take the final cut a little lower and let the lawn rest with its roots deep. The crew mows and trims through the growing weeks and keeps the beds and borders in order, so the change of season is a handoff rather than a scramble. Good maintenance is mostly rhythm, and a yard shows it the following May.
