My father in law's house has two large oak trees in the front yard and they cannot keep grass alive near the tree. The house is located in south Alabama so it gets pretty hot down here. The ground around the trees are elevated a couple of feet. He said they used to have very good grass but it slowely died and since then they have not been able to get any to grow. The yard gets almost no sun, except for what leaks through the limbs of the trees. Does anyone have any recomendations on the type of grass or methods to get the grass to grow. Thanks in advance for any help on this. Also they would rather keep the trees and the shade rather than cut them down and grow grass. So cutting them down is not an option.
