What is Snow Mold? Snow mold is a lawn disease that likes cold, damp weather. Ideal conditions are temperatures around 30-40 degrees for an extended period of time. The disease grows in long grass over winter under snow or a wet layer of leaves.
What can be done this Spring? If the weather warms up after the snow melts, and we get up in the 60s fairly regularly going through April, for the most part the snow mold will take care of itself. If we experience a long string of days in the 40s after the snow has melted, this is the environment where snow mold will become more prevalent. In this case, the best thing to do is to rake the lawn to allow air to get to the blades of grass and if you see areas of dead grass, rake out the dead grass and reseed after the temperatures have stabilized above 60 degrees.
What can be done to prevent Snow Mold in the future?
1. Long grass over the winter is a breeding ground for snow mold. Though you don't want to cut your grass to stubble right before the snow comes, make sure you do not let it get long. Grass cut a little shorter over the winter can go a long way in keeping snow mold out of your lawn come Spring.
2. Take the time to rake up those leaves in the Fall. An accumulation of leaves on your lawn over the Winter creates a welcome environment for snow mold. In the fall, use your lawnmower to mulch leaves into the lawn.
3. Be careful with the amount and type of nitrogen fertilizer you use on your lawn. Though fast release nitrogen fertilizer can do a quick job of producing a green lawn in a short period of time, Nitrogen can promote the growth of snow mold. Using a low-nitrogen, slow-release lawn food, provides the right kind of nutrients your lawn needs for storing energy over the winter. I recommend, Scotts® Turf Builder® WinterGuard.
