Snow mold tends to grow where patches of standing snow or ice have accumulated. They become noticeable after the snow melts. There are two types of snow mold: grey and pink. Snow mold can continue to grow after the snow has melted if the grass remains cool and wet. Grey mold will stop growing when temperatures become higher than 45 degrees Fahrenheit, but pink snow mold can survive in temperatures up to 60 degrees Fahrenheit.
