Everything green in Avon is borrowed from the Eagle River and paid back through careful watering. Mountain Organic Landscaping & Irrigation works that account — sprinklers started up in May, adjusted through the dry blue heart of summer, blown out before the lines can freeze in October — alongside mowing, trimming and cleanups, and snow plowing, shoveling and ice control once the ground goes hard. The sun at this elevation is fierce, and a lawn will show a missed zone within days, so the heads get walked and watched. Getting the water right is the whole difference between a yard that survives a mountain summer and one that enjoys it. Then winter arrives and the same driveways get opened, which is a satisfying way to know a property from both directions.
