St. Augustine lawns are prone to many problems during the growing season. One of the major problems we see with a St. Augustine lawn is a customer using the inappropriate herbicides on their lawn. Before applying any herbicide, read the entire label and make certain that the product is labeled for St. Augustine. If your lawn species is not written on the label, do not assume that the product is safe.
Yet another problem with St. Augustine is fungus. There are two fungus problems which become evident on most St. Augustine lawns during the warmer months of the summer. The first fungus is gray leaf spot. This fungus presents small circular lesions on the leaves. Although unsightly, gray leaf spot is not life-threatening to the lawn. Brown patch, however, has become a major disease on the lawn during mid to late summer. Brown patch will look as if someone poured hot oil on the lawn the night before. Within a few days, these areas will die and the infected area will continue to grow in size. Both of these fungus problems are easy to treat with a granular fungicide.
