July in Groton can go dry fast — the Nashua runs low, the hayfields go pale, and a lawn shows the strain before anything else on a property does. Edwards Irrigation is in the business of keeping that from happening, watching how water moves across a yard and making sure the grass actually gets what it needs. Alongside the watering care comes the ordinary work that keeps a lawn honest: mowing, trimming, edging, mulch in the beds, cleanups at both ends of the season. There is real pleasure in walking a lawn in August and finding it still deep green from the drive all the way to the treeline. Serving Groton and the towns nearby.
