I am a lawn guy that is inevitably going to have to get in the fert business. I have a potential client with a high end residential that is wanting me to do total care of. From the lawn to lots of shrubs and landscaping. His current guys is losing about 5 shrubs a year, and he doesnt think he is fertilizing and caring for them correctly. So my question is, is there a good book for learning about fertilizing and turf care as far as the chemical aspect is concerned? Im not worried about the trimming aspect, but the fertilizing is really worrying me, and i dont think it should be. I just want to get it done right guys, thanks for the input in advance. If it makes a difference i live in south central (wichita area) kansas.
