Take All Root Rot

Root rot is one of the most common fungal diseases affecting St. Augustine grass, causing it to turn yellow or brown. This disease targets the grassroots, which can ultimately lead to the grass wilting and dying. 

Poor Watering

Water Adequately

Watering your lawn consistently is essential if your St Augustine grass has turned to straw due to lack of water. 

Consistent watering helps to promote healthy root growth, which is essential for a lush, green lawn. You should water your lawn for at least 30 minutes twice a week during dry periods.
