Today i had the opportunity to dig out the stump of a previously 5 metre tall chinese elm. The owner gave me a hand but it still took the two of us the best part of two hours to get it out of the hole.
Chopped back as many roots as i dared and stuck it in a makeshift recovery box until next spring, when i hope to cull the majority of the non-lateral root mass and put it in something shallower.
All i'll say is despite the hard slog (i dragged this to its planting spot solo when i got home), i'm stoked to finally have a huge elm stump to develop. It's currently in a sheltered spot by the fence, out of direct sunlight for a few weeks and has been thoroughly watered and seasoled. Any advice on aftercare is appreciated.

Another photo of it potted up to follow in a couple days.
Cheers!
