Cool-season grasses, like Kentucky bluegrass and ryegrass, thrive in cooler temperatures. Proper preparation for winter ensures a healthy and vibrant lawn in the spring. Lower your mowing height to about 2.5 inches before the first frost. This helps to reduce moisture retention and the risk of snow mold.

Apply a fall fertilizer rich in potassium. This nutrient helps strengthen the grass roots, improving their ability to withstand winter stress. Avoid fertilizing too late in the season, as this can promote tender growth susceptible to frost damage. Core aeration is beneficial for improving soil drainage, allowing air, water, and nutrients to reach the grass roots. This is best done in early fall to give the lawn time to recover before winter.

If your lawn has thin spots or bare areas, overseeding in the fall can help thicken it up. Choose a grass seed variety suitable for your climate. Reduce watering as the weather gets cooler. However, ensure the soil is adequately moist before the ground freezes.
