By late October the maples along De Witt's older streets let go all at once, and a lawn can travel from green to buried in a single windy afternoon. Stonecrest Property Services works that turn of the calendar closely, clearing leaves before they mat and sour the turf, making the final cuts of the year, and trimming and edging so the yard heads into the cold looking deliberate. Earlier on, the same routes run to a mowing schedule, with the spring cleanup that pulls winter's grit and twigs up out of the grass. Turf in Onondaga County does much of its real growing in the shoulder seasons, and that is exactly when attention pays. A yard put away right in November comes back better in April.
