I’m really just curious if its possible these have completely fused together and share a vascular system. Is the scrub oak just going to grow around the douglas fir? Its been boxed with pumice and the native soil and appears to be in decent health.
I don’t think they’ll fuse to the point of sharing a vascular system, but maybe they have fused close enough that you will have trouble separating the two without seriously hurting one or both.
The third photo is in a box? You did lift these trees. They look interesting…
Did the roots just ‘pull’ apart?. How did they do this summer?
