Bare spots can be caused by a number of factors such as pets, insects, too much shade, and lawn disease. Fixing them is a simple process. All you have to do is follow some basic steps.
Rake the soil to give your new grass a place to grow. For 50% thicker results, apply Turf Builder® Seeding Soil, over the area about one inch thick.
Apply high quality Scotts® Turf Builder® Grass Seed with Water Smart and gently rake about ¼" of soil over the seeds.
Water is essential for thick, fast germination. Water enough to keep the top layer of soil moist. When the seeds sprout and the grass matures, you can resume normal watering.
