How Does Winter Dormancy of Tall Fescue Affects Lawn Growth? 

During dormancy, which typically takes place when temperatures drop below 50°F (10°C), Tall Fescue experiences a significant slowdown in growth. In essence, the grass goes into a state of rest, causing visible changes in its appearance and growth patterns. During this period, Tall Fescue ceases to grow, and its color may turn pale or straw-like, giving the lawn a less vibrant appearance. 

Adding lime to your lawn is a versatile task that can be performed at any time and is one of the most cost-effective ways to improve soil conditions. In Virginia, soil tends to be naturally acidic, with pH levels ranging from 4.5 to 6.3 in areas that have not been limed. While a pH of 5.0 might be suitable for blueberries and azaleas, it is not conducive to most lawns, which require a less acidic environment. 

During the winter months, it is imperative to prepare your lawn with the steps below. 

1. Keep leaves off the lawn 

With leaves continuing to fall, it’s important to remove them as soon as you can as it’s not good for your lawn. You should rake your grass regularly during the fall and remove all the dead leaves. You can also use a leaf blower to remove the leaves as well.

A perennial grass that has both rhizomes and stolons and is capable of forming a turf or mat of fine leaves. Several varieties of bermudagrass are cultivated for use as lawn and pasture grasses, however this weed has developed into a very troublesome and hard-to-control weed in agronomic crops, landscapes, nurseries, and turfgrass. Bermudagrass is found throughout the southern United States, as far north as southern New Jersey. 

What are these tan areas in my lawn?  

Are you seeing tan areas in your fescue lawn this winter? If so, you have begun to witness dormant Bermudagrass. Bermudagrass is a warm-season grass that goes dormant (turns tan) over the winter months. While Fescue grass is typically green year-round but may be discolored or yellow in harsh, wet winter months. When winter temperatures consistently fall below 50 degrees, fescue will go dormant because weather conditions aren’t ideal for development and growth.
