by Typhula spp., while pink snow mold (also called Fusarium patch) is caused by Microdochium nivalis.

The following steps can be taken to minimize damage in future years:

    * Avoid excessive applications of nitrogen fertilizer in the fall.
    * Continue to mow the lawn at the recommended height until it is no longer actively growing. The taller the grass, the more likely it will mat down and encourage snow mold development.
    * Rake up leaves in the fall.
    * Manage the thatch layer to avoid accumulations of more than ½ inch.
    * Spread out large snow piles to encourage rapid melting. Use snow fencing to minimize snow accumulation in problem spots.

If you get snow mold rather than use fungicides it is advisable to rake the lawn well and if necessary overseed.  By June you won't even know the problem ever existed.
