Merrimac gathers itself around a small square, and just past it the road climbs into orchard country where the rows still run in straight green lines. MRK Enterprises brings that same order to lawns — mowing on a set week, edging along walks and drives, trimming close, mulching beds, pulling weeds before they get a chance to seed, feeding and overseeding wherever the ground has gone thin. Spring cleanups clear off whatever winter left behind; autumn ends with the leaves lifted from the grass and the beds put down for the cold. From the street, an even cut and a clean edge tell you the whole property is being looked after. Merrimac leads, and the towns along the river follow.
