Can I build up my yard with dirt to cover the exposed tree roots ?

I had the same problem and took my saw zaw and cut the root horizontaly off at grade level. I Did this to two trees last fall because the lawn mower bounced over them. None were cut off more than half the root to get the ground flat. This spring the trees are fine. I don't know that a tree professional would recommend this but I did it . Try at your own risk. Jay

Good luck, keep us posted!

I would not do any cutting . Make a good mixture of peat moss and garden soil meant for trees and spread about two inches all around the trees. If that is still not enough apply mulch as well.

Thanks for all the answers .. I will keep you all posted when I make a move!

We built a bed around the tree base and planted flowers, which worked very well. Of course, I'm pretty sure nothing kills Laurel oaks - well actually something does; we eventually had them removed. Messy, messy tree and not at all as interesting as Live Oaks.
