Ok so ive been up and running for 2 months, so far so good. Well some of my lawn are starting to look a little funny. I understand we have had ZERO rain, that might be causing the problem. So heres whats going on, Ill try to load pics later. #1 A customer has a 10'x10' in the middle of his lawn thats not growing, around it is, but hte spot almost has a red tint to it. Also theres another spot that isnt growing, and it follows my mow line. I mow at 4in no shorter, and ive even raised it. #2 Some of my lawns, at the drive way edge are browning up bad, and its about 8in of it all the way up the drive way edge. #3 another lawn has spots were the grass has dies and roots are exposed, and its an irregular patteren, but its big 4'x3'. It looks like its been eaten. Now, i have some yards that are BEAUTIFUL!! so its almost hit and miss.
