cpll, St. Augustine requires different apllications rates. Also there are some ferts and even squirts that you cannot use on it as well. I will give my father a call in Florida and see who or what he uses. Fesuce can look very good if people are willing to pay for it. Our strains of Fescue here take about 3 full years to become adult enough to sustain themselves. I can try to get other info from Howard Johnsons commercial line you.
