March brings warmer weather and melting snow, revealing the lawn that once was the best in the neighborhood underneath. Snow mold is often left and must be dealt with immediately. Some grasses are more susceptible than others. If your lawn has straw colored, matted patches, it has most likely been affected. Lightly rake affected areas to break up matting, otherwise the area will require seeding. Get out there soon! Raking before your first fertilizer application is crucial to avoid breaking the pre-emergent crabgrass barrier.
