That's not a bad idea actually - thanks! I have a follow up question
to my original post however. How far should I be from the tree in
order to reduce the damage?
As far as possible. place a fence as a barrier to keep yourself from
compacting the soil. Compacting the soil of pine is a serious problem.


Should I go out to at least the drip
line?

YES

I really wanted to have some portion of the patio under the
tree because it is the only shade I have in this area.

If the symplast dies from compaction or removal on non-woody roots you will
not have shade for long.

Why not raise the patio? Contact me to discuss if interested. 610-864-5251
If not, ok then.
