By late June the flat farm ground along the Fort River goes so green it looks lit from underneath, and Amherst yards take the hint. Teagans landscaping keeps them in that same key: mowed on a steady rhythm, edged clean where the grass meets the walk, trimmed close around posts and stone. The town asks for range, from tight in-town squares near the common to long open lawns running out toward the Hadley line and shaded strips along the rail trail. Spring starts with raking winter out of the beds and ends, months later, with the last leaves carted off before the ground hardens. A lawn cut well on a hot afternoon is one of the plainest good things there is.
