Not much for me to say here, as this should be directed towards the individual or individuals who did the damage ... not as a general question to lawn care providers. My question would be to ask if your state requires "experience" to be one of the "qualifications" to receive a state license to do this type of work? In my opinion it should. There are to many things in life where people are "qualified" to do things only because they have been taught the steps and procedures to do the job ... but do not have the actual hands on experience to do it correctly. We wouldn't want a doctor to do surgery on us if they had only been schooled in the how-to procedures. It seems to me that for the most part, the reasons for this thread on this forum was to point fingers at LCO's as if to say "what makes you think you are smart enough to do this work?" I notice your website says that you do not mow lawns ... so why is it you come here to question those who do? I don't believe the person or persons who did this damage post on this forum ... and they are the ones who really need to be questioned. I don't feel my intelligence, or most peoples intelligence on this site needs to be questioned because of someone else's practices. Have a GREAT day.
