High-plains summer builds its weather out of nothing: blue sky at noon, thunderheads stacked over the Front Range by three, and rain crossing Rueter-Hess Reservoir in a gray sheet before it has fully arrived. The Grass is Greener Lawn Care Inc reads those afternoons the way Parker homeowners learn to — cut ahead of the storm, let the water do its work, come back to turf that answers. The routine is unglamorous and it is everything: weekly mowing, trimming along fence lines, edging the drive, aeration into the clay, fertilization and weed control. There is real satisfaction in a bluegrass lawn that stays green through a dry stretch of August, and in the sharp line where grass stops and concrete begins. Parker is the home ground, with Castle Rock, Lone Tree, Franktown and Elizabeth close at hand.
