I grew a Hungarian Yellow four years. I dug up the rootball in fall and plunked it, attached soil and all in a suitable pot. I didn't prune. It pruned itself multiple times but always made new leaves. Production slowed down but it made a few during winter. In spring back in the gh it went, right into the beds, again no special treatment. My gh sheeting blocks enough light that hardening off is minimal. Maybe prop a sheet of something to shade it if necessary.
Have fun!
