On Main Street the tavern porch has been watching the year turn for a very long time, and the yards behind it turn right along with it. Four Seasons Lawn Maintenance keeps up with each stage, mowing through the long green stretch of summer, edging and trimming so the lines stay honest, and clearing the leaves when the hardwoods finally let go. Every part of the calendar asks something different of a Watkinsville lawn. Knowing what it wants, and when, is most of the job. The rest is arriving and doing it properly.
