Since winter solstice is two weeks away, we are going to go over what happens to cool season Fescue Grass in winter.

What happens to cool season Fescue grass in winter?

Fescues tend to have an easier time surviving extreme winter weather than they do in summer. Fescues will slow down their growth rates in the middle of fall and then enter a natural dormant state in winter. As winter arrives, Fescue turf drives a high amount of development in its roots as well as strengthening its cell walls. It is a good idea to fertilize Fescue at the beginning of fall and then at the end. This is especially important if your lawn has low nutrient levels in its soil. Fertilizing with nutrients such as phosphorus and potassium aid in Fescue’s cell and root development.

Should I be worried if my Fescue lawn turns brown in winter?

Fescues should not turn brown during the winter if they are healthy. The most common sign of a healthy winter Fescue lawn is that it keeps its dark green coloring throughout the winter. If the lawn is improperly fertilized, the grass may take on a yellowish color. This color means the grass is lacking in access to nutrients like nitrogen. Frost or heavy snow can cause Fescue to also turn brown. When Fescue is coated in frost, its cells can become brittle, and the turf can get easily damaged if any pressure is put on the lawn. Therefore, it is imperative for foot traffic and lawnmowers to stay off the lawn until it can thaw out.
