From the top of Powow Hill you can see the marshes and, on a clear late-summer day, the flat blue line of the ocean beyond them. Kirby Landscaping LLC works the yards spread below it — mowing, trimming, edging, bed maintenance, and the spring and fall cleanups that set a property up for whatever comes next. August lawns ask for a different hand than May lawns; knowing when to cut high and leave the roots their shade is most of the job. A tidy border where grass meets driveway is the smallest detail on a property and the first one anyone notices. Done well, an Amesbury yard holds its shape right through the long amber weeks of September.
