Yellowing Bermuda Grass in South Texas

Although St. Augustine grass has long been a popular choice in South Texas, in recent years, the more drought-resistant Bermuda grass is being planted. Yellowing of Bermuda grass is a sign of distress.

  1. Fungal Diseases

    • The first symptom of a fungal disease infection, such as spring dead spot and take-all patch, is yellowing of the grass leaves. The Bermuda grass will become discolored in patches, often circular in shape. Control consists of a combination of cultural and chemical methods.

    Chinch Bugs

    • Chinch bugs are common in South Texas. The insect is 1/6 to 1/5 inch in length with a black body and whitish wings. Chinch bugs feed on Bermuda grass, causing damage. A sign of infestation is irregular patches of dead grass surrounded by a halo of yellowing. Control includes cultural methods and the use of insecticidal soap.

    Iron Chlorosis

    • South Texas soil pH tends to be high, between 7.5 and 8.0. The alkalinity may prevent essential elements in the soil from being available for uptake by Bermuda grass. Iron chlorosis is a condition where the grass in unable to take in sufficient iron and results in grass blades that turn yellow. Proper fertilization will provide relief.
