Fertilizers with 12% or less nitrogen by weight. Check with your local garden store to determine availability and suitability of these fine products for your lawn. Remember that you'll need much less slow-release fertilizer than typical, water-soluble, high-nitrogen fertilizer. These products contain no phosphorus.
Products containing phosphorus (New York State Law prohibits the use of lawn fertilizers containing phosphorus except in certain conditions, including the establishment of a new lawn or when indicated by a soil test. See your garden retailer for more information.)
