Elm branch gone bad?

[porcupine]

American Elm I was pruning yesterday. It almost looked like 2 braches fused together, one having died a while ago? Has anyone seen one like this?

Looks like they may have grafted. Cool. Still early to prune elms here.. Do you have Dutch elm disease up there? I'd imagine its probably pretty cool already there

That is a GREAT pic. Shows codit...and sound wood as well as decayed in different stages. Cool.

the Elm ban lifts September 1st here. Dutch Elm has not been seen around here. I heard of a case in southern Saskatchewan. Hopefully we stay free of it.

That's a great photo. I've been taking a good number of photos during certain dismantles or prunes to create an interesting portfolio for clients to see when explaining issues they may have in their trees.

I am wondering if we are looking at a limb that was injured more than once in the same area. I was zooming in on the wound wood (wall 4) but couldn't see clearly enough what was going on...seems like an injury on the top of the branch (with lots of heartwood) resulted in callous tissue forming, followed by a crack later down the road. Soo cool looking. Thanks for sharing!

Good job cutting back to small laterals instead of a "proper collar cut"

Very tree-friendly work there.
