Trout Brook slips under half of West Hartford without most people noticing it, and the yards along its line stay green when the rest of August has gone tired. Lawn Ranger keeps those lawns on a weekly cut, running the fence lines with a trimmer, edging the driveway aprons, holding the mulch beds dark and the shrubs off the walk. Dusk in late summer is the good hour for the work, when the mowers quiet down, the sprinklers come on, and the grass still holds its lines. Overseeding in the cool of September brings back the shade thinned spots near the maples. Then the leaves arrive, and they come off before they can mat down into the turf.
