Seasonal Guides for Your St. Augustine Maintenance
In the active growing season, St. Augustine needs about 1 inch of water a week from natural rainfall or irrigation.
St. Augustine mowing heights during the summer generally range from about 2–4 inches. When mowing during the summer, never remove more than 1/3 of the leaf blade at a time.
Do not overwater the grass. St. Augustine only needs about 1 inch of water weekly. Water for longer periods of time, less frequently and in the early morning hours. Take rainfall into consideration.
It is not recommended that you apply an herbicide at this time. Once temperatures exceed 85 degrees Fahrenheit, the herbicide will damage the grass.
During the fall, mowing will occur less often—keeping your St. Augustine slightly higher than the regular 2–4 inch height will encourage deeper root growth which helps it survive in colder temperatures and during winter dormancy.
Water less as temperatures drop—too much water will lead to disease.
It’s recommended you apply a fungicide at preventative rates as this will help the grass enter colder months in a healthier condition.
