There is a week in Bristol when the black prairie soil finally lets go of winter, the ground gives underfoot, and everything that looked dead starts pushing green. Evolution Professional Services begins its year in that week — raking out what the snow flattened, sweeping the grit off the walks, taking the first cut of the season. From there it settles into a steady rhythm of mowing, trimming and edging that runs until the corn comes down in the fall. The reward is simple and visible: turf that holds its stripes and a border line you could follow with your eye from the road. The route covers Bristol, Yorkville, Montgomery and the farm lanes between.
