I live near Winston Salem (NW), NC. I have a customer (ONE) who is not satisfied with the tone/color of his grass. He has a very healthy, weed-free (within his threshold) lawn. But, it's not DEEP green. I applied a winterizing fert. in early Jan./another round in March and the last round in May. His neighbor does have VERY green grass. I'm not an agronomist. I have a license to apply chemicals, but my experience in fert. applications is something I admit to. I follow the program my supplier outlined and I do keep the pH in the proper range. I'm sure I could apply *So when you get a speeding ticket, do you beg the judge for the maximum fine? (_______) and get his color darker. But, at what cost???? My thinking is he's a little unreasonable. But, I need to speak to him, intelligently, when I speak to him. What do you guys do in a similar situation? Thanks.
