What do you guys estimate a growth rate for healthy, well fertilized, irrigated St Augustine in South Florida? (IE: __ inches per week in the summer _____ inches per week in the winter?) Im curious because, I have a customer who uses a National Fert Co, and they lay it on heavy, and OFTEN. Even during the winter months I am chopping off 3-5 inches after 10-14 days. The summer forget about it...Its like the amazon. I measured today and in one spot, I took off 9 inches after 13 days, and it hasnt even started to rain yet. Is this amount of growth excessive? And can you actually over fertilize St Aug?
