Wow Jeremy. Are you that comfortable with that approach for any Elm. I know they are vigorous as I have several already, but . . .
I normally wouldn't consider that approach unless I was dealing with a Willow, Wisteria, etc.
Nevertheless, I do think there may be something to the notion of cutting off the main root on each end and lifting because I do think it has rooted to some extent where it meats the ground in that area. I would likely come up with some feeder roots if I did that, but I'd still have a T at the end.
Are you kidding!

I love the trunk line. Oh well. To each his own.
