I don't think you are supposed to be able to get St. Augustine grass to grow this far north. My Dad has about 7k sq. ft. of it in NW Georgia and it is also in the yards next to his. I believe these lawns have been active for the past 20 years or so. Is beautiful in the summer. My question is about proper fertilizer and when to apply it and what is best mowing height? My wife and I have operated a small LCO for the past 12 years i the Atlanta area and this is the first time I have attempted to care for this lawn. Everything we work with is Fescue and way different problems. I did check with our Lesco supplier but they don't even list a St. Augustine program for this area. Thanks for your help. Cleve.
