Thank you very much for your information. This is a big help.
I think I have the basic idea of how to do this now.
these vines are quite young now, but growing VERY fast. I was just afraid to
wait in my pruning because of all the growth.
Someone need to make a video on this pruning technique. Is this the same
method used in grapes or muscidines?
