Fog sits on the East Branch Croton until the Southeast hills lift it off, and by then the first mower is already down off the trailer. Alejandro & Son Landscaping LLC keeps lawns across this reservoir country — mowing, edging, string trimming, and the cleanups that bracket the growing season at both ends. There's a particular pleasure in the first pass of the year, when the grass answers back and a yard remembers its own shape. By evening the line along the walk runs straight, the clippings are swept, and the place looks like somebody meant it. Southeast and Brewster sit at the center of the route, with Patterson, Carmel and the roads out toward Putnam Lake close behind.
