You need to tell us a bit more. How old is it? Where is it growing? What direction does it face?
Position sounds fine and the plant healthy so, unless you bought it in flower, it's likely to be too young. Some wisterias are seed grown, and they can take up to seven years to flower.
The other point is have you pruned it correctly - look here for instructions:
I planted two expensive grafted hybrids three years ago, and they still don't look as if they are going to flower this year!
I have let them grow to fill the available space.. This year I am going to cut back all but the essential growth, and will prune these back in July to encourage flower bud development next year.
It may well be the pruning ... mine is about 3 years old ... I've never had flowers, but last year I looked at a couple of videos about pruning (when and how). I followed these rules and this year I've had loads of flower buds !
Thats the good news, the bad news is that with all this rain, the buds got completely waterlogged and they've just rotted and dropped off.
Still, better luck next time !
Si I think the answer could well be to prune according to the YouTube pruning instructions !
hi ive had my wisteria about 4 years and it didnt flower untill i gave it a hard pruning now it has got lots of flower heads on it i think if im not mistaken you prune it twice once in the spring and again in the autumn thats what i do and it works
In Boston market yesterday I saw some wisteria "Amethyst Falls" that were only 70cm tall, and they had several big flower buds. I am sure one of mine is the same variety!
So, out with the secateurs in June, cut out all but the strongest stems, and cut the remaining ones back by half. Hopefully I'll see buds developing next February, and I'll cut back again to fatten them up.
Grafted plants are supposed to be the best and in flower when you buy but when I got mine I would have needed a second mortgage to buy what I wanted so went for a small potted 'whip'. I had a new garden at the time so there was nothing in it so all plants purchsed where small. That wisteria took over ten years to produce any flowers at all! Sadly, at that time I didn't have any pruning information so just stopped it looking sad & weeping willow like! Once it started flowering it was lovely but not the blue I expected, more of a lilac color. I have now moved house and didn't have the heart to did it up as it had spent so much time 'settling'. I am now trying again with some bare root plants and so far they are still like dead twigs!
My wisteria produces plenty of flower buds but then they just seem to stall and wither. Can you help?
Hi Gaye sounds like the frost has got to it.Fleece it up on a night or it could happen again
I have had problems getting my wisteria to flower. Here is the info I have been given from a gardener who specialises in them.
Prune side shoots back by 80 per cent in the second or third week of August (I'm based in the Midlands he did say the weeks would vary for different parts of the country)
In February feed lightly with Fish Blood and Bone.
Prune again to 4 buds when the buds begin to swell in the spring.
Feed lightly with Phosphate to encourage the flowers.
I'm determined to get this plant flowering, it's five years old and came from good root stock. It's become a bit of a challenge now.
I have 4 year old blue wisteria it seems fine flowers comes in early june but my westeria flowers are small very dense and heavy not like what we usaualy see in the pictures and the fragrance is a bit spicy is it a different kind or am i doing some thing wrong here
We've had wisterias for over forty years. None are younger than about fifteen.
They are a bit like weeds, very resilient.
You can prune them at any time.
I do the main prune between Christmas and New Year. I used to do it three or for weeks later, but there's "climate change in the Mersey Valley for you," we haven't seen snow other than an overnight sprinkling, for seven years.I cut the laterals back to two to four buds.
Once they have flowered, I spend the rest of the Summer and early Autumn cutting back new laterals and removing some completely. Then can grow several inches overnight.
We've six wisterias.
Two here. The grow from each side of the pergola and cross in the middle.
This on a side fence.
This on an old tree stump.
This, the youngest which is pink, took eight years to flower and they were very weedy for the first couple of years. It grows from below the back window of the kitchen and over the 6ft fence between the house and garage. It's just to give a bit of colour to the side of the house.
We also had this, which had some really ugly thick branches which were restricting the gap between the garage and the pool pergola rail.
As it had layered itself along the very narrow bed between the path and the garage in several places, so last year, I encouraged this new growth up the side of the garage.
I then cut the main plant off at the root.
The remaining stem is the one that trails round the top of the fence between the garage and the house and over the pergola on the back wall. The bungie cord is to keep the trunk close to the garage wall, I've taken in a "couple of reefs" in it in the last year.
This was the new growth by mid-summer.
This year it has produced laterals from the single stems, so I expect flowers next year, though it did produce a few this year. I didn't bother to take any photos.
None of these get any special fertilizer, maybe a bit of general plant food now and again, but plenty of water.

thank you for such a detailed discription , you have such beautiful collection of wisteria
mine is not really slow to grow flowers are plenty as looking at the size of plant may be i am in canada does it make sense ,but my dilemma is fowers are not lose cone like you have mine are very thick closed cluster of petals it look beautiful but i wanted to have one like yours i think i'll get some pictures and post it
Beautiful wisteria , Doghouse riley.
Are they all grafted, or do you have any on their own roots.? I took a layer off of mine. It tends to flower better than the grafted one.
We inherited this one and I gave it a good tidy in December/January. After flowering it was much too wild and woolly so I cit back all the stems that were hanging too low or too far out or trying to disappear under the roof behind and it has not only grown back well but is flowering again, as is its pal which only had a light prune after flowering.
OH is so chuffed with them - both lilac - that he bought me a white one to grow on a trellis and pergola we haven't yet built. It's sat in a pot with framework and doing well.
They do need two prunes a year to promote flwoering buds instead of just growth. For info, see this advice form the RHS - https://www.rhs.org.uk/advice/profile?pid=242

I've really no idea whether they are grafted or not. The one on the garage wall was there when we bought the house in the summer of 1972. The houses were built in 1965. The previous owner said it had never flowered. But I pruned it in the following January and it flowered. All the others except the pink one we bought in garden centres when they were actually flowering. The other was very small.
For anyone new to wisterias, they should buy them when they are flowering, or check them, if later in the year, that they have some of the "serrated spines" that are left after all the blooms have fallen.
Thankyou Doghouse riley
here are some pictures of my not so happy wisteria, i bought it from a garden centre and have no idea
what kind it is and if it is grafted or not, basicelly i chose this spot to make a polite privacy curtain between our deck and neighbors my idea was flower would b long enough to give us beautiful curtain
these flowers are not more then 6''
please help me understand my wisteria ,fyi i never pruned it afraid that it would take years to grow back now i see the bark on the old stems are peeling off
