Hartford sits in blueberry country, where the fields run flat toward the horizon and the Paw Paw River winds through the low ground east of town. Green Thumb Lawns works the yards in between — mowing on the weekly turn, running out the fence lines, tidying beds and walks when the season opens and again when it closes. Fruit-belt summers are warm and wet, and everything grows at once. Staying ahead of that is the job, and a lawn that never once looks like it got away from you is the result.
