The message
from Chris French and Helen Johnson
contains these words:

Not had a vine before, what sort of pruning/care does it need. It has
good frame work of old wood across the roof, though a few gaps, the new
growth is growing madly and some is dangling down into the conservatory.
It seems to have plenty of flower bunches.

You prune vines twice in the year, once in the spring and once before
the following spring.

It's probably the wrong time to prune now - but when the fruit has set,
cut the lateral with the bunch(es) back so that you leave around three
or four leaves beyond the first bunch.

If the first bunch is weedy, you can snip that, and prune beyond the new
first bunch.

If you prune too early, the vine can bleed profusely, and may even die
as a result. It's best to prune one lateral when the fruit has set, just
to make sure it won't bleed badly when you cut the rest.

Ask again after the fruit has ripened, and you'll find someone to tell
you how to prune it back for next year's crop.

Give it plenty of ventilation, and *NEVER* give it nitrogen.
