Rake snow mold patches lightly and fertilize for recovery

What to Do

When melting snow reveals circular patches of matted, gray-white or pinkish grass, gently rake the affected areas to break up the matted turf. Apply a light dose of nitrogen fertilizer (0.25-0.5 lb N per 1,000 sq ft) to encourage new growth into the damaged areas.

Why It Works

Snow mold (gray caused by Typhula, pink caused by Microdochium nivale) thrives under prolonged snow cover. The matted turf traps moisture and blocks airflow. Raking lifts the blades, allows drying, and the grass crowns underneath usually survive. Light fertilization stimulates recovery growth to fill in.

Tips

• Most snow mold is cosmetic and lawns recover fully on their own.
• Prevent next year's snow mold: reduce last fall mow height, avoid late-fall nitrogen, and break up snow piles that linger.
• Severe cases with dead crowns may require overseeding the affected patches.
