With many northern locations still experiencing cold weather and, in some cases, battling snow on the ground, it’s difficult to get into the outdoor season spirit just yet.
For those that live in the north and northeastern parts of the United States, I probably don’t need to reiterate just how long and cold this past winter was. We can certainly expect that lawns will have suffered and that there will likely be some winter damage. Turf damage can come in a number of different forms, including ice damage, snow mold, and damage from moles that like to burrow in under the snow, leaving unsightly tracks all over the lawn. When the weather does eventually warm up and that lawn care/gardening spirit does kick in, here is what you need to know:
Ice Damage: Can occur after the soil has frozen and there has been a thaw or rain that refreezes directly on the turf before it has had the chance to run off or seep back into the ground. As the snow melts and refreezes, it can create ice sheets over the lawn, typically in poorly drained areas. As the ice sheets melt away, damaged areas of turf may be evident.
Ice damage on the lawn is only a major concern following extended coverage. Unfortunately, when it does occur, it is considered the most severe form of winter damage, often requiring costly turf renovation.
Snow Mold Damage: This turf disease can come in two different forms – pink snow mold and gray snow mold. Pink snow mold can occur with or without snow coverage, whereas gray snow mold usually requires prolonged snow coverage. Expect to see both this spring as the snow melts away. For obvious reasons, pink snow mold gets its name from the coral pink hue that it expresses, while gray snow mold may look like someone peppered your lawn thanks to the black sclerotia associated with the mold. Although neither form of the disease will kill your grass plants, weakening of the lawn’s structure can occur. Your best option is to try and rake it out. Warmer weather and fertilizer will eventually help the turf fully recover.
Mole Damage: Mole damage often appears in the form of mounds of soil in the spring or fall, resulting from moles’ underground tunneling. This type of damage is often superficial in nature, and the lawn will heal once it has been thoroughly raked up and fertilized. A good way to discourage moles from invading your lawn over the winter months is to lower your grass cutting height just before winter hits (during the last few mowings). This lower mowing height will not provide the moles with much protection under the snow, and they will ultimately move off to other areas.
Keep those lawns healthy,
