Dear Neil: In a recent column you mentioned that St. Augustine shouldn't be fertilized between mid-June and early September due to the possibility of gray leaf spot causing the grass to turn yellow. I had fertilized my lawn a few weeks earlier, and it did just that. What can I do to control the leaf spot? When should I apply the "winterizer" fertilizer I have on hand?
