Now that the snow has finally melted and warmer temperatures are upon us, many lawns are showing signs of a common fungal disease called snow mold (gray snow mold in particular). Snow mold occurs when spring conditions allow warm unfrozen ground that was recently covered by melting snow to activate an existing pathogen. The issues start when a pathogen is present, spring temperatures are between 30-40 F and the soil/turfgrass is fairly saturated. Snow mold may be found in lawn areas where drainage and air-movement is poor and especially where snow has been piled and/or is slow to melt. Damage can be as minimal as just a few small circular shaped yellow/matted down lawn areas or more widespread (conditions dependent). As the lawn dries and warmer weather moves in the disease becomes dormant until the next opportunity arises (late fall/early spring). Damaged lawn areas should be repaired by first raking the problematic areas (very important), add a light layer of topsoil (as/if needed), plant a premium disease resistant grass seed blend and finally cover the repaired lawn areas with a light layer of peat moss to complete. After the lawn repairs have been completed and soil temperatures warm beyond 50 F your lawn will rebuild its lost density and look as if a problem never existed.
