Well despite my predicament at the moment I decided to risk sitting up for a while and attacked my elm today and have now attached a nice air-layer. Hopefully I wont kill the damn thing. Nothing ventured nothing gained. I decided to layer this one as you can see the trunk is quite straight and the length of the trunk from the soil line to the first branch is quite a way up. So one solution was to just remove the top of the tree but what a waste so the air layer. For the top half I am hoping to create a formal upright and as for the bottom I am not sure yet it has a mass spread of roots at the base.
Roots First remove the layers Now add the Sphagnum Moss Now we wait and see if it works

2 trees for the price of one hahahaha
Feel free to comment I am by no means a layering expert.
