In late spring the drainages off the Castle Pines ridge run full for a few short weeks, snowmelt heading north through Cherry Creek and gone again by June. Rivers & Waterfalls Landscaping opens its mowing season in that stretch, when the turf comes out of dormancy all at once and grows faster than it will all year. The early cuts set the tone: mow, edge, trim the awkward pitches where yards fall away toward the gullies, and clear out whatever winter left behind. There is a plain pleasure in the first clean pass across a lawn that has been brown for five months. The work carries on through Castle Pines and out to Sedalia, Larkspur and Castle Rock.
