By late June the light holds past ten o'clock, and people are still walking the loop at the Civic Center long after the mowers have gone quiet. Parshall Lawn Care Experts spends the week making something worth that hour — mowing on a steady rotation, trimming close around fence posts and mailbox stones, edging until the line between concrete and green looks like a decision rather than an accident, then clearing the clippings back off the drive. The growing season is short this far north, so fertilizing and weed control get timed to the grass instead of to the calendar. Spring means raking winter out of the yard; fall means lifting the leaves before they mat down over the crown. In between there is the plain satisfaction of a lawn that looks tended on a Friday evening.
