St. Augustine is one of the most prevalent turf grasses in Texas because of its propensity to thrive during heat and drought conditions. St. Augustine performs particularly well in areas of shade and high traffic. One of the best features of St. Augustine is its deep rooting potential, which makes it very durable. St. Augustine grass is also really nice to look at because it is dark green and very thick.
In southern Texas St. Augustine performs exceptionally well, much better than in north Texas where temperatures can bet a bit too cold for St. Augustine. The most common issue with St. Augustine in north Texas (especially in the Dallas-Fort Worth area) is that it is susceptible to disease in the the spring and fall when its going in and out of dormancy. Its low cold tolerance makes it a much higher maintenance turf than Bermuda grass in cooler climates. St. Augustine is also susceptible to Chinch bugs which should be controlled in the summer time.
The best way to maintain St. Augustine is to follow these simple steps:
1. Apply 2-4 pounds of nitrogen per 1,000 square feet per year
2. Cut the lawn at a height of 2.5 to 3.5 inches using a sharp mower blade
3. Water twice per week for 45 minutes during the summer months
4. Monitor the lawn in spring and fall for potential disease issues (St. Augustine decline, brown patch, summer patch)
5. Monitor for insects from May to August
