Normal turfgrass growth requires a balance of 16 essential elements. A deficiency in any one of these nutrients can interfere with normal plant growth. The three most important (and most familiar) nutrients are nitrogen, phosphorus and potassium, which are the elements described by the numbers you may see on the side of a bag of fertilizer. These numbers describe the percentage of each nutrient that can be found in that particular mix. For example, 10-6-4 fertilizer contains 10% nitrogen, 6% phosphorus, and 4% potassium. You can also think of these numbers as representing how many pounds of each nutrient would be present in a 100-pound bag of that fertilizer mix.

Nitrogen is responsible for enhanced shoot growth and density, plus a darker green color.
Phosphorus promotes root growth and seed production.
Potassium helps with disease resistance, heat, cold and drought tolerance by regulating the absorption and retention of water.

Treat your lawn with an organic based fertilizer, similar to a 10-6-4. It should contain iron and other micronutrients to provide a balanced healthy diet for your turf. We recommend that you fertilize your lawn 4-6 times per year, applying a total of about 4 pounds of nitrogen per 1000 sq. ft. per year.
