Answer: Landscape contractors almost always use a perennial ryegrass, fescue and Kentucky Bluegrass mixture to spray onto the ground. The greenish cast is a combination of fertilizer and organic matter (usually shredded paper) to help hold the seeds in place, keep them moist, and feed the plants after they germinate. You can purchase a similar combination in rolls at the garden center. They are essentially mats of shredded paper impregnated with grass seed and sprayed with fertilizer.
