In the shaded older blocks near Bow Mar the big trees do half the work, and the lawns beneath them ask for a different kind of attention than the wide-open sunny yards a mile east. Griego's Outdoor Services reads both, keeping lawns cut and borders clipped through a midsummer that can hit ninety by noon and cool off the moment the shade swings around. Grass under trees wants a higher blade; grass in full Colorado sun wants a break. The work is unglamorous and the result is not — a yard that looks even, tidy and attended to from the sidewalk. That is the whole ambition, repeated weekly.
