When the ditches come up in spring, water runs the laterals out of the South Platte and the whole valley changes color inside a week. Landscape Design & Lawn Irrigation LLC works Fort Lupton lawns on that same calendar — a spring cleanup first, then weekly mowing, close trimming and clean edges through the growing months, and a clearing in fall to finish. Grass at this elevation lives on a narrow margin, and keeping it green here has always been a matter of timing more than luck. There is a real pleasure in a yard that turns thick and even while the fields past the fence go dry and pale. That is the result the work aims at, week after week.
