YES if you put it up against the bark it will kill most trees. What kind
of tree and how old.

Can you provide any good documentation of that? I have a neighbor who added up
to 2 feet of soil around the trunk of two poplar trees on my side of his yard. I
tried to explain it would kill the trees, and he said "my sources say it is no
problem". I'd sure like to get better data.
