By the third dry week of a Grovetown August the sandy ground has let go of every drop it had, and the difference between a green lawn and a straw-colored one comes down to whether the sprinklers are doing their job. Grovetown Lawn & Sprinkler works both sides of that line — installing and repairing irrigation, adjusting heads and zones so water lands on grass instead of pavement, and mowing, edging and trimming the lawn it keeps alive. A misaligned head can waste a whole summer; a corrected one saves it. Beds get watered and weeded on the same rounds, and in fall the system gets shut down ahead of the first cold snap. There is quiet pride in a yard still holding its color when the block has gone dormant early.
