Scotts Turf Builder Thick'R Lawn Sun & Shade Mix, 12 lbs. is designed to your thin lawn into a thicker, greener yard with ease. This 3-in-1 formula combines grass seed to fill in bare spots, fertilizer to nourish and thicken both new and existing grass, and soil improvers that promote stronger root growth. Together, these elements work synergistically to help you achieve up to a 50% thicker lawn with just one application, depending on your lawn’s current condition and care. I for use in both sun and shade areas, this mix is applied twice a year—in spring and again in late summer or early fall. For optimal results, use a Scotts spreader following the settings on the product label, and keep the soil surface moist daily for the first two weeks after application. Model Number:
