Save on your water utility bill.
Cover your lawn with 8-10 inches (they will compress to about 3 inches) of wood chips, turn off your lawn sprinklers and reduce your water utility bill considerably. A pro arborist will bring you chips for free, available when they trim tree branches. Usually, they need to haul them and pay to dump them at the landfill. Bringing them to your home saves them money and saves you money.
