With proper preparation, Don King Landscaping ensures that your sod not only takes, but thrives. This requires a clean underlayment with the right amount of healthy, clean top-soil. Proper grading is critical for drainage and levelness. Our sod is grown north of Longmont and freshly cut. An alternative to our sod service is hydro seeding. Hydro seeding is a grass planting process that has been used on everything from city parks to residential lawns. It is fast, simple, economical, and efficient.
