I did one with a lawson's cypress (C. lawsonii), I did a complete ringbark on a piece which was growing very strongly, dusted w/ rooting hormone and wrapped in damp shagnum moss. I did mine in the late summer; it grew roots within about 3 weeks. However, I did get slight dieback on the branches, although I made sure the moss was always damp. Perhaps I did it too late in the year, it was just an experiment. Unfortunately, I had to get rid of it as I was running out of space. You will probably have to experiment as well!

Chamaecyparis tend grow roots quite readily, as you will see with those multi-trunked garden specimens whose branches come into contact with the ground, near the base of the tree.
