I was doing some research on this and had some questions. First, in the time Ive been in biz no one has asked me about fertilizer or pesticides. Im getting hit with it every day here this season. New client today wanted all the weeds in his yard gone and the grass nice and healthy. Im ashamed to say that this is my weak point but that is fixing to change quickly. I need to see about getting my license, taking a course or are there any good reading material for this? I hate to be asked a question by a client and cant give an answer I feel good about. I also want to know more about pruning and shrubbery trimming, what is the best time, how to feed etc. My client base over the years has been "we dont care when you do it or how, long as it looks good" Im trying to be much more professional and educated this year. I have graduated from the scrub status!
