Transplanting wisteria

We have the most beautiful wisteria but the problem is that the pergola it grows on needs to be rebuilt as the retaining wall that supports it is collapsing. Is it difficult to transplant a wisteria? I've read that now is roughly the right time to transplant a wisteria but the builders aren't able to start until July. If we put the root ball of the wisteria in a large pot is it likely to survive until late summer? Perhaps taking cuttings is the way to go but would be good to think about transplanting as well. Thanks

 

How big is it and how long has it been there?
Dont think cuttings are a viable option.

 

I completely rebuilt a pergola.... This one.




I supported the wisteria on a tall wooden frame I built, I was able to turn it away from the space required. They're quite "bendy."

 

Thanks both and lovely photo.
I reckon the wisteria must be at least 10 years old, if not older, as the main trunk is around 8 inches. The issue we have is that the wisteria and another couple of large bushes have been planted really close to a retaining wall in a border above the pergola which is down the next level of the garden. The roots have cracked the wall right through so it has to be rebuilt and we have to move the wisteria and bushes. Whoever built it didn't think through the problem of having large roots right next to a wall so we're having to rectify the problem. I'm just sad to lose the wisteria as it's such a lovely one but that's better than a wall which you can see through!

 

Dont think its moveable myself.
If you cant do as @Doghouse Riley riley suggests I think you need to dig it out and maybe plant a new one once the building work is completed.

Is it not possible to do a hard prune and make allowances for the roots in the new structure.

 

Thanks Pete. We will certainly allow for the roots when the new wall is built, and plant the wisteria a good distance away. I need to find out the name of it so I can try and get a replacement. It's not one I've seen before - it has deep purple flowers fading to a pale lilac, really lovely.

 

This photo is of my husband's aunts' house near Dublin. it is post having to completely renew the huge balcony as the original balcony was demolished by...yup Wisteria . It looked amazing when in flower but caused £1000s of pounds worth of damage left unchecked.

 

There are loads of varieties
I grew one called "purple patches" for years on a dodgy pergola, the flowers were so long you couldn't walk under it when flowering, it had bi coloured flowers, in a similar way to some lupins that you see.

Think it was W. floribunda type.

 

That's the problem with wisteria it's a "rampant thug." At the height of summer, side shoots can put on six inches overnight.

 

Thanks for the lead Pete, these two look pretty similar. I now have to track them down!

 

We've five wisterias, including this pink one, one branch of which comes out of garden and around the side of the house. We'd had it eight years before it decided to produce any blooms, despite it being pruned correctly. Can't remember the name of the variety.
