I have done it as Paul says, no problem. It is very bad to cut vines in
the spring, all cutting needs to be done in the fall after the leaves
are gone - no exceptions. Also of note, I was able to move one vine
(one inch thick in my case) six feet by burying it midstem, and cutting
the vine rootside of the buried portion the next fall. They need water
and fertilizer to produce properly, and of course protection from
birds.
