I do an all granular program and just switch dealers due to prices. For those who do all granular fert on centipede. What brands and anylasis are you using. It's hard to find granular with little N from chloride. I was using Sol-U-Cal pear 4-0-6 with iron at .5 lbs per 1000. Hoping to find some other products to replace it. Hoping Greeddoc and almond will chime in again.
