The Espoma Organic Lawn Starter 3-6-3 is a high-quality lawn food that helps establish new lawns. It contains higher phosphorus compared to other lawn foods resulting in a stronger root system and thicker grass. This specially formulated fertilizer is derived from organic and natural ingredients without added fillers or sludges. It works by gradually breaking down its vital nutrients, providing a safe food supply that can last the entire growing season. Best applied when starting to grow grasses from sod, seed or plugs, or when over-seeding existing turf. The product comes in a granulated form for easy spreading.
