The initial visit and the treatment were prompt and professional. However we were quoted 2…read moretreatments at $1500 each for 7 Live Oak Trees. The young man doing the treatments was gone less than two hours after starting. I did not count how many times he poked the handy aerator into the ground around each tree, but it wasn't very many. They called back to schedule the second treatment two months early, I decided to call the owner. He made noises about his manager not looking at the calendar (or something like that). When I discussed the price and the amount of time spent with Mr Fulgham, he gave me a line about how much it costs, blah, blah. Well I just finished building my own custom house and I know very well it doesn't cost that much to have a guy come to my hose for two hours. Mr. Fulgham also told me that he charges the same per tree no matter what or who. So I suggested that he come take care of the one tree in the worst shape right now, so that should be about $250, right? Nope, he told me that since I wasn't happy, he would no longer service my trees. As for his patented system? Yes he has a patent, I have read it. It does include injecting fertilized water between air blasts. Other than that, it is the same thing done by lots of other people. And there are other ways to fertilize trees. You will get a tree treatment and they will be very nice about it. Just be prepared to pay for it.
