East of town the ground simply opens — the Black Canyon of the Gunnison drops away in the dark, and the light that clears that rim at dawn reaches Montrose before it reaches almost anything else. Zenterra Lawn and Landscape starts in it, mowing while the air is still cool, trimming along walls and bed lines, edging the walks so they stay sharp against the gravel. Summer is steady work: fertilizing, weed control, aeration and overseeding for turf that can take valley sun without going thin in August. Autumn brings the cleanup, leaves and stems and spent annuals gone in a single afternoon. Quiet, repeatable, and the kind of yard people notice without quite knowing why.
