I have a pin oak and it was planted 6 years ago in my back yard. The leaves are yellowish with brown spots on them. Last year they had me put Bayer liquid fertilizer that you mixrd with water and it was good for a year. This year I got another oppinion and he had me put ironite down because of no green and was in acidic soil. He said this will green it up. It gets plenty of water since I have in ground irrigation system in place. I just layed the ironite down 1 week ago. Thought I would write to get another oppinion.
