Wisteria

I hardly dare admit to this problem, but my four year old wisteria has not flowered yet.

I bought a good plant- of course the name escapes me, something like Black Prince or Black knight which was a darker flowering variety.

It makes loads of growth which I prune to two fingers as reccomended, and I feed it well (suspect this could be the problem - all leaf no flower)

Anyone any ideas please?

 

Unless its grafted, its a still a bit young yet. They can take up to 7 years to flower - but so well worth waiting for. Give it a potash rich feed fortnightly during spring, and see what happens next year.

 

I took care to buy a good grafted root stock and paid the price for it, this is why I am baffled.

If I wait much longer it will pull my house tpo bits it is so vigerous.

 

Are you pruning the long shoots back in summer?
That what I used to do with mine, not got it now.
Then another lighter prune in winter.

 

Yes pete - I was instructed by expert to prune first week in August and then light winter prune, and have done this.

When the plant was obviously not going to flower, I told Martin to hard hack it again to two fingers and it has just gone mad, this is why I suspect it has too much food, so making leaf not flower??? Having said that it is at the back of a hungry box hedge.

think I will just have to continue what I am doing and live in hope???

 

What do you mean by "hack it back to two fingers"?

 

What I mean it pete that I have trained a few main stems and there are masses of leaders which I have cut back to about the length of two fingers - as advised.

the "two fingers" have then shot out and produced masses of sub shoots, it is unbelievable. I mean less than a month ago when it was not going to flower we cut back to save energy, but it has yet again taken over whole plot.

I think MF there may be something in the 7 year thing as my sisters took this long to flower. there is one accross the road - must be a hundred years old, nothing ever done to it and it is fabulous even in winter when you just see the twisted knarled form - FANTASTIC!

 

funny but reminds me of one of them william Morris wallpaper things. If anyone needs pictures of it flowering just shout, but not very exciting.

 

Oh and present owners have this house as a holiday cottage - well over �£1,000,000 job I would expect.

Oh but previous occupiers were real old school gardeners - can't even start to explain.

 

Glad to hear that others have same problem. We got our Wisteria courtesy of a Daily Telegraph offer about 6/7 ears ago - a very weak looking plant has struggled but left alone for the last two years it finally produced flowers this year.
No secret techique but I did fill the hole with alot of compost!

 

I am not sure if my contribution would be welcome here. I bought my Wisteria siniensis 'Prolific' less than two years ago at a height of less than three foot, I haven't pruned it or fed it and it's currently in flower (well just one flowering stem). I suspect that it is just the luck of the draw. However I did see on one site the comment
"It is important that Wisteria is given a south or west facing position, for without it the shoots will not ripen and flower buds will not be formed"
