Since it is fast growing, St. Augustinegrass requires frequent mowing during the growing period. It should never receive more than 4 pounds of nitrogen per thousand square feet in one year. At the high rates of fertilization and irrigation, thatch buildup may be a problem. In turn, buildup of thatch can lead to other problems, such as disease and insect damage. St. Augustinegrass is not tolerant of heavy traffic, or cold weather.
Chinch bugs are often a problem, causing leaves to rapidly begin to wilt and turn brown.
Yellow spots are often associated with chinch bug activity. In addition, brown patch can be a nuisance, creating brown circular patches up to several feet in diameter that usually warrant treatment. Read and follow label directions carefully. St. Augustinegrass is best suited to the southern one-third of Arkansas. See our Calendar for information on the care of your St. Augustinegrass.
