Grape

I've inherited a grape that's in the conservatory. No grapes this year but it's been very prolific with it's growing! Now obviously the leaves are turning and falling, making my conservatory a bit of a mess, it's a daily job picking up the leaves off the floor. My question is, should I wait for all the leaves to fall before cutting it all back, as there are still quite a few green leaves. Thank you

 

Thank you @wiseowl and @Loofah

There are a couple of very thick, woody branches that have been used to train the grape, and we've used hooks that were in the frame of the conservatory roof to tie it up as it went along making quite a nice canopy sadly no fruit this year but maybe that's something I didn't do to help it. If I can cut it all back now then I will, as it's looking quite messy now!

 

I have an outdoor grape that I prune in Feb /March. I think the main issue is to do it when the sap is not rising as it is very prone to 'weeping'. If the leaves are falling I think the sap must be dormant for the winter. Is the conservatory heated?
If it still has green leaves could you hang on for a few weeks even if it's getting on your nerves? You could make a sample cut and see if it weeps.

 

The conservatory isn't heated, it only gets warm in winter if there's a nice sunny day the sample cut is a good idea, I'll give that a try when there's some light

 

You can cut it back now if you want.
Bear in mind if you want fruit you need to get somekind of pruning plan from now on.

If its just done as it wants for the summer it's probably in a bit of a tangle just now.

 

We've tried making it grow more or less where we want, but the main part is a bit of a tangle

 

I've only ever grown them by the old fashioned methods used here.
There are other ways used on the continent but I've never understood or tried them.

Mostly it involves a lot of pinching out during the summer, even some pruning of new growth, new current years growth does not bleed if pruned in the summer months, its only when you cut into the previous years growth when the sap is up that you get bleed.
