This service is not optional. The extra charge is levied when the grass is of sufficient length at the time of the first mowing as to require more time than usual. On a regularly scheduled, weekly basis, we tend to your lawn with properly trained personnel, and appropriate and well-maintained equipment. This service includes weekly mowing and trimming of all grass areas as well as edging along concrete walks, driveways, and patios every two weeks. Of course, we thoroughly clean up the debris we cause and take the grass clippings with us
