Now that the snow is melting, you might be asking “What is snow mold?” Snow mold is a lawn disease indicating that your once, green lush lawn is suffering from a fungal infection. It occurs, usually, in cold & humid weather. Snow mold presents itself as white or gray areas of matted lawn. Sometimes the areas will have a pinkish border around the areas of matted grass. Symptoms show up (& possibly get worse) any time from the 1st snow cover until late spring.
Why do some lawns get snow mold?
- Fungi present in the atmosphere are like the “seed” of snow mold
- Winters of excessive moisture, prolonged snow cover, & temperatures between 32 – 45
- Leaving your lawn too tall going into winter
What to do about snow mold in your lawn?
- Use a plastic lawn rake – Use a leaf rake to allow the snow mold to dry out. Rake out areas of matted grass as soon as the snow melts.
- Seeding – Select a seed blend that has some resistance to Snow Mold & other common turf problems.
- Snow mold Treatment – Disease applications are generally not practical and often fail. Some lawns that have an annual history of snow mold may consider a disease prevention, prior to the first snow cover.
