I have a shag bark hickory in my front yard, and a depressed spot where
probably there was a tree (unknown). Grass is most difficult to grow
there and under the shag bark hickory. I'm wondering two things 1) Does
the hickory tree also produce a toxic substance that would keep grass and
other plants from growing and 2) Is the depressed spot possibly the site
of a walnut or more likely, given that there are lots of hickories and
few walnuts in the area, an old hickory tree site.
