I admire a sunburst-locust tree and have taken some cuttings from the
tree. Was
wondering if anyone has ever been successful at root propagation from
cuttings
of locust trees?

http://www.botanyworld.com/gleditsia.html

doesn't mention cuttings or root propagation, but says that
thornless honeylocusts like "Sunburst" should be propagated
by grafting onto seedlings in the spring. I wonder if honeylocust
scions could be grafted onto pieces of root as well? That works
well for some other trees

Hope this helps.

cheers
