Daytona Beach measures most things in laps and fractions of a second, but a lawn here runs on a slower clock: the steady cadence of a mowing day and the clean return of an edge along the drive. Certified Outdoor Solutions, LLC does lawn care in a city where July noon turns the air to glass and the thunderheads stack up inland by mid-afternoon. In that heat, St. Augustine grass grows as if it were chasing the checkered flag, and holding it level, trimmed and swept is a race of its own. When the storm passes and steam lifts off International Speedway Boulevard, a freshly cut yard is among the first things on the block that looks finished again. For Daytona Beach, that's a finish line worth crossing again and again.
