Cuttings cold weather vines started in March of 2002 survived the winter
of 2003 and are now about 2-3' long tied to vertical stakes. These are cold
weather varieties like Kay Gray, Sabrebois and Delisle originally from the
former Soviet Union that can hopefully survive the brutal winters here in
Eastern Ontario. Next spring I plan to cut back to two trunks so I will have
a spare in case one dies. The question is, should I trim back the wood now
or wait until spring. I fear predation by deer or die back due to the cold.
I could trim each vine back to 6" or so. Anybody with experience on these
varieties?
