So interesting! We don't have any expanse of woodland here and the only thing I've done with a stump was to use it for clematises to climb. The stump finally rotted down, after 24 years, and I eliminated the remants in December.
It was cut down in either '91 or '92 because it was too close to the house: photo from 2007

2012 - the rotting progresses:

I relocated this unique piece of wrought iron a friend gave me (from curbside trash) in the 80's:
Now I'm anxious to see how well the clematises grow on it this year.
