I'm looking at the middle of a 3" tree root, that's intruded under a slab and along plumbing. How can I determine "which direction to the tree"?
I've cut a section out of this root. One end is damp, the other is literally dripping water (and has dripped for days). Given the position of the root, either way could be the tree trunk. Digging to find out which is not practical.
Is there any such thing as a tracer die that can be injected, then found on the tree trunk?
