Morning in Dacula arrives low and white, fog pooling in the bottoms toward the Apalachee before the sun burns it up off the pasture grass. Alexander Group LLC works those hours, when dew still weights the blades and a mower leaves a darker track behind it. Mowing, trimming, edging and blow-down across the ridgetop neighborhoods of this corner of Gwinnett County — the ordinary work that makes a yard look cared for from the road. By midday the fog is gone and the lines are still there, running straight to the mailbox. That is the part worth doing well.
