Turfgrass In Oklahoma


Benefits of Lawns


A well tended lawn has more value than esthetics. It may add up to 15% of value to the home, in addition to its other benefits. Turfgrass is also an environmental plus by absorbing CO2 and releasing oxygen. Enough oxygen is released by a 2500 sq. ft. lawn to supply a family of four. Turfgrass helps conserve water in the soil; it has a remarkable cooling effect on the ground and surrounding structures. Houses have been shown to need less AC when a healthy lawn is present.
