First off, I'm not licensed...yet. Still have a year with current company to qaulify to take state exam. After which I am starting my own business. I live in Florida and will be dealing with St. Augusine-grass only. I plan on applying four fert. apps per year but will be on the property once a month. On month's I'm not applying fert it will be just to spot treat for pests if needed ie. chinchbugs, weeds, fireants....all big problems down here. My question is: since i will be on the property every four weeks to spot treat for pests do you think I need to apply fertilizer with preventatives ie. demension, atrazine, talstar. If I can get away without them it will save me big money on my products. I'm just concerned that I may be setting myself up with constant battles with pests. any comments are appreciated.
