Out at Chicopee Memorial State Park the pines hold the cool of the morning long after the rest of the city has warmed through, and June smells like water and needles. Diamond Irrigation & Landscaping carries some of that green back into the neighborhoods — lawns mowed on a rhythm, edges run true along walks and drives, shrubs shaped, beds mulched and kept clear of weeds. A lawn that gets steady attention all through a valley summer stays a deeper color than one rescued in August. Cleanups bookend the year, so the grass starts clean in April and finishes clean in November. Chicopee lawns and the towns beside it, kept on schedule rather than in a hurry.
