Saturday morning in Cummaquid sounds like mowers, one street after another, from the Yarmouth line back toward the marsh road. Mr. Mow It All is somewhere in that chorus, cutting, string trimming and edging yards where July grass grows fast enough to get away in a single week. Sandy Cape ground rewards a sharp blade and a regular schedule more than anything clever. Mulch, weed control and seasonal cleanups round out the routine as the year turns over. A finished lawn on a hot Saturday, still smelling of cut grass, is the plain and complete version of the job.
