Early along the Farmington Canal trail the cottonwoods are still dripping and a mower is already running somewhere past the treeline, which is how Southington starts a summer day. Scarfas Lawn Care LLC belongs to that first shift, handling mowing, trimming, and the tight edge work, plus the cleanups that open and close the year. Near the old canal line the ground stays damp and the grass grows heavy, so the cut has to be timed and the clippings dealt with or a lawn goes ragged in a hurry. Choosing the right height for the week ahead is quiet, unglamorous skill. The result is a yard that looks the same good way on Saturday as it did on Tuesday.
