A recent storm knocked down one my evergreen trees which probably had
a diameter of at least twenty feet, so nothing was growing underneath
it. I plan to plant grass there, and since evergreen trees are acidic
I was wondering if I should lime the area first. I plan to purchase
some topsoil, and should I lime the area before I put the new topsoil
on.

The area gets sun all day. I live in Pittsburgh, and what type of
grass would be good to plant? I know there is the "Penn State Mix",
and that is what I think I will plant when the local township dug up
my yard last year to put a now drainage line in, they replant the area
with the Penn State Mix.
Thanks

Tom
