I guess it all depends on what you consider to be acceptable turf performance. If there was a once a season turf food for the south it would be putting a lot of people out of business if it worked lol.. I fertilize 7 times a year but my release rate is dependent on moisture and temp. The great thing is when it gets really hot like it is now it will never burn even if there is some very slight water stress due to restrictions on outdoor watering. It does smell like a feedlot sometimes when I put it down heavy !
