Pests Plumbing Safety Seasonal Structure Disaster Warranty Winterkill and Snow Mold Winterkill is a general term used to described injury of turf in the winter. Winterkill can be caused by many things, including low-temperature injury, winter dehydration and fungal diseases. Freezing and thawing in late winter accompanied by high soil moisture is a common cause of low-temperature kill. Winter dehydration occurs primarily in Northern regions under prolonged periods of cold and windy conditions with little or no snow cover.
Snow mold is a disease that also occurs mostly in Northern regions.
It is caused by several different fungi and affects many turfgrasses. The symptoms are irregular to circular patches of water-soaked, yellowed, or bleached turf. They sometimes bear a whitish, gray or pinkish cast. Snow mold commonly becomes noticeable after a period of snow cover over unfrozen soil.
