A Saturday morning in Fort Lupton starts with dew sitting on the bluegrass and the smell of it lifting as soon as the sun clears the eastern fields. Bernardos lawn service works those mornings — mowing, trimming, edging and clearing the clippings so a yard reads crisp from the street by lunchtime. On this stretch of plain a lawn is something you earn: the air pulls moisture out fast, and the difference between a tired yard and a good one is mostly somebody showing up on schedule. Spring and fall bring the bigger jobs, the raking and the cutting back, the season woken up or put to bed. The rest is rhythm, week after week, all summer long.
