If you have a dog, you probably have lawn spots too. A common indicator of dog ownership, these dead patches surrounded by lush, green growth are caused by the nitrogen and salts naturally present in your dog's urine. More commonly associated with female dogs, though not exclusive to them, urine spots can tarnish an otherwise pristine lawn. You can, however, minimize the damage and get dog burn spots out of your grass by eliminating or diluting the amount of nitrogen that contacts the turf.
Reseed Damaged Spots
Insert the blade of a sharp, narrow spade at a 45-degree angle around the perimeter of the spot to a depth of approximately 6 inches. Cut the roots of the grass with the spade, and lift damaged grass out.
Refill the hole with topsoil until it is level with the soil in the surrounding lawn.
Scatter grass seed on the bare spot. Choose a grass seed mix that matches the surrounding grass.
Tamp the soil down with the blade of your spade, and water the area thoroughly. Water gently for 10 minutes but do not allow water to pool or puddle.
Water every morning for five to 10 minutes until the grass seedlings are well established--about six to 12 weeks. Begin to reduce watering after the sixth week, tapering off gradually into the twelfth week.
