Arkansas lies in the Transition Zone. This means that summer in Arkansas is too hot for Cool Season grasses to perform well and winters are often cold enough to injure or kill Warm Season grasses. Unfortunately, maintaining lawn grasses in the transition zone is more difficult than in many other parts of the United States.
Winters in Fayetteville are too cold for St. Augustinegrass and centipede-grass, and the summer heat and humidity in Texarkana make it difficult to grow tall fescue. Zoysiagrass and bermudagrass are grown in all parts of the state. We rarely have winter damage to zoysiagrass, but cold weather injury to bermudagrass is not unusual.
Promoting healthy growth and avoiding conditions that cause stress to your turfgrass is the best way to prevent a severe disease outbreak. Stressed lawns are an open invitation for a lawn disease to gain a foothold. Optimal maintenance practices are the best way of avoiding stressed turfgrass.
Even if a pathogen is present in the soil, infection will not occur unless the environmental conditions are conducive to disease development. Once turf diseases have become active, they can cause heavy damage if not treated properly. Here is a list of common diseases to Arkansas lawns:
