Big Trees Sugar Hackberry… from cuttings? Air layer?

[Eric H]

I have a cluster of Sugar Hackberry trees in my front yard that need to be cut down. They are each 3-6 inches thick at the trunk, they are 30 feet tall or so.
Is there a good way / are these suitable for trying to root from big cuttings?
I think the root ball (cluster) is way too big to use.
Thoughts?

I would try digging and get one of the root ball clusters, and you could do both. I think its too late in the year for air layering.
