We lost a tree-trunk (one of three) during a windstorm last night. When I cut it off far below the jagged edges I found the trunk was hollow -- how far down, I don't know. It is pointing upward, and certain to catch rain like a basin.
My question is, should I keep cutting until I get to solid wood, or will the stump just rot away naturally without causing any further damage?
The two surviving trunks seem okay.
