Winter is almost here, and with it will come a whole host of things that can threaten your lawn.

In previous blogs, we’ve talked a lot about what you can do in the fall to prepare your lawn and keep it as healthy as possible throughout the winter, but what happens when winter finally arrives? The cold weather brings a lot of unique challenges for your lawn, and there are a number of things that can damage your lawn throughout the winter. Knowing what these threats are can help you prepare for them, and, in some cases, prevent them. Here are the biggest threats to your lawn throughout the winter.


#1. Voles

Voles are tiny rodents that look a lot like mice. They are between four and six inches long and are usually greyish or brownish in color. Voles form runways in lawns just under the snow, and they feed on roots and grass blades. Many people attribute the damage caused by voles to moles. But, if you’ve noticed that there are narrow bands of damage in your lawn, or you’ve spotted areas where the roots and grass have been eaten clean, then you probably have had voles in your lawn. Voles can be trapped, repelled or baited, much like mice.

#2. Crown Hydration

Crown hydration occurs when warm weather is immediately followed by a freeze. The turf grass absorbs a great deal of moisture when it’s warm, and then when the freeze suddenly hits the grass will expand and then freeze, killing the crown of the grass. Crown hydration most commonly occurs during the later winter and early spring, and unfortunately, there’s not much you can to do avoid it. You can, however, work with the lawn care experts at Green Turf to help your lawn bounce back from the damage.

#3. Snow Mold

Have you noticed that there’s a grayish or pinkish crust on your lawn once the snow has melted? This is called snow mold, and it’s actually a type of fungus that can damage or kill your turf once the snow has melted. Gray snow mold is not quite as damaging as pink snow mold, and it typically only affects the grass blades, doing little to no damage to the crown or the root system. Pink snow mold is much more severe, and it can destroy the crowns and roots of your grass. Luckily, snow mold is typically easy to prevent; you simply need to ensure that you are mowing and raking up leaves regularly throughout the summer and fall. Although, in some cases, a fungicide may be required.


During the spring, the summer and even the fall, caring for your lawn is relatively easy, but the winter can throw a few curve balls your way that makes it more of a challenge. In our next blog, we’ll be going over a couple more things that can threaten your lawn during the winter, so make sure that you stay tuned to learn more.
