The backyards off Dobbs Ferry Road are built for August — a hose, a table, kids running the length of the grass until dark. Party On My Yard keeps them ready: mowing on a regular turn, trimming the fence lines, edging the walks, and clearing the clippings so bare feet meet nothing but lawn. Greenburgh grows a soft cool-season turf that stands up to a whole summer of use if it is cut at the right height and never scalped. Cleanups handle the unglamorous half, opening the yard in April and closing it once the leaves are down. A lawn is only really finished when somebody is standing on it, enjoying themselves.
