do oak trees put acid in soil?
Hello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it. The grass is very thin and I was told that is because oak trees turn the soil acidic. I had lime put down last year but the grass still looks the same.ello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it.
