We cut an old grape vine out of our conservatory last year, for various
reasons.
This year the stump, which ran outside, has grown 5 or 6 runners which I
would like to train up the outside of the conservatory. Should I concentrate
on one runner and cut the rest out or let nature take its course.
I don't know the variety, it's a black grape, quite sweet but with lots of
seeds. The position is south facing and sheltered, so frost damage should
not be a problem.
Thanks,
Tom
