There is one week each September when the willows along the Swan River go yellow and every sprinkler line in the valley has to be blown clear before the ground locks up for good. Thetford Landscaping & Irrigation lives on that hinge of the year — system startups in June, head adjustments and repairs through the short green months, mowing the properties out toward Farmers Korner and along the Highway 9 corridor, then winterization, then plow blades back on the trucks. Come January those same driveways get cleared and the walks shoveled and sanded, and there is no guessing where the drifts stack up, because somebody mowed that yard in July. Knowing a property from both directions is the whole advantage. Water on in spring, snow off in winter, one set of hands for a Breckenridge address.
