Yes, that's right, I want to to know if there is any way to _prevent_ a tree stump from rotting out. I've got a giant douglas fir tree that sits about 3 feet outside my kitchen window, and someday it's going to have to go (once they get to a certain size, they have a tendency to fall over). However, the root system holds up a giant boulder, and that would require some massive (and expensive) retaining wall if the stump were to rot away. So.... is it possible to somehow preserve a stump and it's root system? Thanks.
