I am sitting at my desk doing some bills. I hear a mower start up and it sounds like a homeowner version. I decide to take a cigarette break and go sit on the front porch. My neighbor, who is a middle aged single woman and is in the process of selling her house, apparently has hired some local kid who was about 12 to mow the lawn. He has the mower set to cut at about 1/2 inch. Lawn is Centipede and he is basically giving the death knell to everything he cuts. I caught him before he got around one loop and signaled him to stop. I politely said that he needed to move the deck height up or he was going to kill the whole lawn. He seemed shocked to say the least but I implored that I was not here to harass him but that certain grasses need certain types of care. I then showed him what a stolon was and how his chopping them all off would cause the grass to die. I also explained how slowly Centipede grew laterally and he just nodded. He then went around and finished the whole lawn and I did a quick trim of my front yard with the Proline 21 while he was finishing up. He came over and said "thanks, I never knew grass was so cool, can you teach me more?" I chatted with him for about 20 minutes before he had to go. While I feel good about passing on a little education I will probably be losing business to him when I start up again. Wheeeeee!
