Snowmelt runs down Dad Clark Gulch in April, and for a few weeks the greenbelt smells like wet clay and new grass. DC2 Landscaping & Irrigation Services starts its season in that stretch of the calendar, opening yards with a cleanup and then settling into mowing, edging and string trimming week after week. Lots that back the trail take a little more care, because the grass wants to blur into the open space and a firm edge is what keeps a yard reading as a yard. Through summer the cut stays even, the walks stay swept, and the trimmer reaches the corners a mower rounds off. By late October the leaves come out and the lawn goes into winter clean.
