I'd like to tell everyone a little story. I have a friend who owns a landscaping business. He doesn't do major chemical work, but he'll do a few weed & feeds now and then (nothing crazy, he's unlicensed). So....earlier this year we had a conversation, and he mentioned he'd gotten a new lawn account (to mow). He says the "thatch is ridiculous! I can't even find the soil level." I asked who treats it...he says "I do, but he had TGCL do it in the past." He also mentioned that it's a nice lawn, but there are a few dead spots in the front from the little dog. Whatever.. blah blah.. A few weeks later, he was at the property. He called me, I was nearby, so I met up with him. I show up, he was running a overseeder over the lawn to dethatch it. He says "see...check out this thatch man! Have you seen so much thatch before?" I look..I reply.. "that's not thatch, it's bentgrass". This moron thinks that the bentgrass creeping 8" long across the lawn is "thatch". Then he shows me the dog damage spots. It's grubs. What the hell. I basically yelled at him for totally misdiagnosing an issue, and charging a customer huge bucks for nothing. I told him to tell the customer that I will be there tomorrow to treat the grubs, and it'll be $X. I stormed off. If I was american, I'd have a truck full of dylox ready to go Moral of the story: a) I was bored. b) I feel really bad for the customer, paying for all that renovation work when it was stupid bentgrass the whole time. c) Most people believe what the guy that cuts their grass tells them.
