The headwaters of the Belle River gather in the fields around Imlay City, quiet enough that you can drive across them without noticing. July still runs dry out here, and a lawn is the first thing to admit it. Northlawn Irrigation LLC works the growing season from the ground up — mowing, trimming, edging, and the cleanups that open and close the year — keeping turf even when the weather refuses to be. A yard held green through the hardest stretch of summer is worth every bit of the attention it takes. Lawn care for Imlay City and the farm towns around it.
