Fertilizing For Winter
One of the most important times for fertilizing occurs in the fall for cool season grasses (Blue grass, Rye grass, Fescue). A “winterizer” fertilizer is considered to have higher amounts of potassium and/or phosphorous. However, there is no evidence to suggest that extra “P” or “K” in the fall is beneficial to Blue grass, Rye or Fescue. The most important nutrient for fall is nitrogen. The amount of nitrogen needed depends on turf type and maintenance. For high maintenance (ball fields) one to two pounds of nitrogen can be needed for 100 square feet of lawn area. For normal maintenance (homeowners) one pound is recommended. For Blue grass, Rye grass and Fescues the requirement are basically the same.
