Answer: General lawn fertilization should include one pound of nitrogen per 1000 square feet of lawn, per year. Use a 3-1-2 ratio of NPK divided into four applications (April, June, September and late November or early December). For instance, choose a fertilizer with a 21-7-14 ratio of NPK for spring and summer growing. (For reference, Nitrogen encourages top growth for a lush, green lawn, Phosphorous encourages flowering which you don't want on a lawn and is therefore the smallest amount in the package, and Potassium (K) encourages root and stem growth.) You could check your local Home Depot garden center. They typically have just the right fertilizer on sale at just the right time for application in your area.
Best wishes with your new lawn!
