Now that the snow is mostly gone, we are seeing some common early spring problems in lawns.  Here are a couple of things that I observed in my own lawn yesterday.

The first is Gray Snow Mold, caused by fungal organism (Typhula incarnata).  This is a common problems that develops in lawns at this time of year.

 Here is how I know what it is.  The brown fruiting bodies on the tissue are "sclerotia", which are commonly associated with this disease on turf.

 The second problem is a feeding trail of voles that were active under the snow.

There will likely be several turf problems showing up in the next few weeks.   I would appreciate any picture that you have for the blog.
