Lawns Don't Need Phosphorus
When purchasing fertilizer at your local box store you will notice each bag contains three numbers, for example 24-25-4. The first number is nitrogen, which promotes overall grass shoot growth. The second number is phosphate (phosphorous), which promotes strong root growth for newly seeded or sodded lawns.The third number is soluble potash (potassium), which helps grass withstand stress, for example, drought or disease. While phosphorus it's an essential nutrient for establishing roots, it's not a main factor to maintaining growth. It is typically replenished naturally, particularly if lawn clippings are left to decompose after mowing. It's recommended that you use fertilizer with 0 phosphorous & that you not use the same bag of fertilizer all summer. In early spring, when your lawn needs a kick start from the winter, use a fertilizer that is high in nitrogen (30-0-10). For mid summer applications, when the days are long and hot, use more of a maintenance mix (18-10-12).. Finally your last applications of the year should focus on preparing your lawn for the log winter ahead with a fall mix high in potassium (15-0-30).
