Saint David has water where the desert says it should not — artesian wells, a green ribbon of cottonwood along the San Pedro, and birds passing through by the thousand each spring. C & E Septic Services keeps yards in that valley trim: mowing on a schedule that can keep up with river-bottom growth, edging clean along drives, shaping hedges before they close in over a path. Cottonwoods drop something in every month of the year, so cleanup and haul-off are half the job. Grass comes in thick down here, and a level cut with a hard edge makes a whole lot look intentional. The Dragoons turn rose at sundown, and a finished yard sits well under that.
