All grass types are susceptible to diseases and weeds, however, there are ways to prevent, deter and combat these issues through proper Kansas City lawn care techniques. But even with the absolute best care, you cannot guarantee that disease or insects will never be a problem with your St. Augustine grass.
St. Augustine grass is a sturdy type of turf and is able to assert itself over weeds as long as it is healthy and is receiving adequate care. If St. Augustine grass is left to fend for itself, it may become weak, at which time opportunistic weeds will stop popping up throughout your landscape. This is especially true if the lawn is already infested with insects or has been infected with a disease. St. Augustine turf is usually found to have broadleaf and grassy weeds, however, chickweed, clover and henbit have also been found by lawn care specialists to be a menace to this type of grass. These weeds respond best to hormone-type herbicides that are applied in the early spring. Other weeds such as fescue, crabgrass or annual bluegrass require a different type of treatment that includes precise applications of pre-emergent herbicides.
In addition to fighting off weeds, St. Augustine grass is also susceptible to a number of turfgrass diseases including Helminthosporium, brown patch, SAD, Pythium, gray leaf spot, rust, downy mildew and more. Most of these diseases are caused by the presence of fungi and can be easily controlled by a knowledgeable lawn care company. SAD is a virus disease for which there is no chemical solution, which means only defiant types of St. Augustine grass are resistant to the disease.
Brown patch and gray leaf spot are the most severe diseases caused by fungi infecting St. Augustine turfs. Although these diseases seldom destroy St. Augustine, they weaken and thin the grass to the degree that the lawn is extremely unattractive. Precautionary treatments of fungicides are most effective against these diseases.
To keep your St. Augustine lawn primped and pristine, call your local lawn care provider and ask about their weed and disease control programs.
