First light comes slowly to Bethel, sliding down the western hills and pooling along Greenwood Avenue before it ever reaches the yards behind it — and that is the hour GNL Landscaping & Tree Services is already working, a drive cleared to bare pavement, a crew reading the lean of an old oak before a saw is ever started. Their days run from tree removal, stump grinding and chipper work to masonry, retaining walls, gravel pathways and driveways, yard leveling, drainage, irrigation, excavation, planting and transplanting, mowing through the green months and plowing through the white ones, with emergency calls taken around the clock. What they leave behind is the sort of thing you notice with your feet: a wall that holds its slope through a wet March, a path that sheds water instead of pooling it, a lawn edged crisp against stone. In a town stitched together by brooks, ledge and stubborn glacial soil, that is honest satisfaction — a yard that keeps its shape from mud season to the first hard freeze. They work across Bethel and the towns around it, and out farther into Connecticut, New York, Rhode Island and Massachusetts.
