What is the recommended mowing height for St. Augustine grass?

The recommended mowing height for St. Augustine grass is indeed between 2.5 to 4 inches. Maintaining grass at this height is essential for promoting healthy growth and ensuring optimal photosynthesis. When St. Augustine grass is kept within this height range, it helps develop a robust root system, enhances drought resistance, and reduces the likelihood of pest and disease issues.

Mowing at this height allows the grass to retain moisture and nutrients more efficiently while preventing the grass from becoming too stressed during periods of heat or drought. Additionally, a taller mowing height can improve the lawn's ability to compete against weeds and maintain a lush, dense appearance. Keeping the grass within the recommended range supports overall lawn health, making it more resilient to environmental stresses and maintaining its vibrant green color.
