My dear wife, who died two years ago, did not want to kill a Douglas fir seedling that "volunteered" at our patio.
After a half-century, the small seedling grew up in a large tree. The tree is upheaving patio slabs, it's too close to the house, and its roots are growing into the basement. Never mind, the District of Saanich ordered digging a hole next to the house to see that the roots in the basement belonged to the Douglas fir. I found it strange, but we must be lucky the municipality did not want to tear down the house.
