We live in Brooklyn and felled a tree in front of our brownstone because the roots were damaging the foundation. We call the tree a “weed tree” and sometimes it’s called a ghetto elm, but I don’t know its official name. Now that we’ve felled it, we’re stuck with the stump (about 10 inches in diameter)and the roots. How do we get rid of the stump and roots so we can plant a nice new tree that will not damage the house?
