Winter Kill in Indiana: The Cold-Weather Plagues Affecting Your Lawn

Here in Indiana, winter can do a number on our lawns. The infamous term “Winter Kill” refers to the decline and death of grass and plants over the winter from many different causes. Between the cold temperatures, dry wind, snow, and hungry rodents, our lawns are under constant stress during the winter. Here are a few of the most common forms of winter kill in Indiana.

Crown Hydration

Another devastating form of winter kill is crown hydration. Crown hydration is a form of winter lawn damage caused by the harsh elements. When temperatures climb above freezing for an extended period of time, it reactivates the grass. The plant starts pulling water up through the roots and stores it in the crown. If the temperature plummets below freezing, the water freezes and expands. This causes the water-filled cells to burst, killing the grass.

Crown hydration isn’t something that’s easily prevented because it relies on the weather. The best way to prevent this form of winter kill in Indiana is to properly prepare your lawn for winter. Consistent lawn care and efficient maintenance throughout the year give your lawn everything it needs to take on the winter stress.

Snow Mold

Snow mold is another cause of winter kill in Indiana. This fungus grows under the snow during winter. It makes its home in matted grass and excess thatch. There are two different types of snow mold: gray snow mold and pink snow mold. Gray snow mold presents itself as white or gray fuzzy mold growing in patches of saturated, matted grass. Pink snow mold is pink, red, or copper-colored and looks a lot like gray snow mold. The difference is that pink snow mold attacks the roots and crown of the grass, often resulting in winter kill. Gray snow mold does not.

Prevent snow mold with consistent lawn care throughout the year and by preparing your lawn in the fall with strategic lawn maintenance. Mow your lawn until the grass stops growing to prevent matted grass. Remove all leaves and lawn debris in the fall so the mold has fewer places to form. Aerate your lawn in the fall to help with drainage and reduce excess thatch. Finally, don’t allow snow to pile up in your lawn, especially around the driveway and sidewalks.

Winter Desiccation

Finally, winter desiccation is another common form of winter kill in Indiana. Winter desiccation happens when there is no snow covering the grass but the temperatures remain below freezing. The frozen ground doesn’t allow the grass to pull in moisture from the roots. The dry winds in the winter sap the blades of grass of all their existing moisture. In a short amount of time, the grass dries up and withers away. The grass ultimately dies of dehydration.

Similar to crown hydration, winter desiccation is a difficult form of winter kill to prevent. The best way to prevent desiccation is with a consistent lawn care schedule throughout the year. Make sure you meet all the seasonal needs of your lawn to ensure it’s strong and hardy when winter rolls in. A healthy lawn is better equipped to take on the stresses of winter.
