Ballfields and front yards need the same thing all summer long: a steady cut, a clean edge and someone who shows up. East Side Mowing Department LLC keeps lawns around Houston trimmed — lawns mowed on a steady week, string-trimmed around posts and hydrants and mailbox stones, cut sharp along the concrete. Midsummer heat can stall the growth for a stretch, and then one Tuesday thunderstorm brings it all back at once. There is real pleasure in walking away from a yard where every line runs the same direction and the walk is swept clean. That is what keeps a street looking even from one end to the other.
