Managing Saint Augustine Grass

St. Augustine relies heavily on the care you provide for it to thrive. It can survive with little care where rainfall is sufficient, but often needs help making it into a trophy lawn. This grass will require fertilization, mowing and supplemental irrigation to achieve the weedless, dense, green turf you desire.

St. Augustine Problems

St. Augustine is prone to many problems including diseases, insects, and weeds. Some of the diseases that St. Augustine is susceptible to are SAD, brown patch, gray leaf spot, pythium, rust, and downy mildew.
