Homeowners in the East Metro area of Minnesota, including Hugo and Stillwater, stand to benefit from healthier, greener lawns in the spring if they apply winterizer fertilizer during the recommended window. However, applying fertilizer too early or after the ground freezes can lead to nutrient wastage and environmental risks, such as runoff into local water bodies. Minnesota's Phosphorus Lawn Fertilizer Law prohibits phosphorus use unless a soil test indicates a deficiency, further emphasizing the need for proper timing and compliance.
