How many years did your wisteria take to bloom?

23 replies

IndieRocknRoll · 19/04/2025 18:52

I bought a grafted wisteria around 2.5 years ago.
it’s planted next to a fence in a very sunny well drained spot.
its grown like an absolute weed from a little twig into a monster! I have to cut it back a couple of times a year and trim it across the top to stop it going over the fence.
I was really hoping for some flowers this year - three small flower buds appeared but haven’t come to anything. It’s a huge mass of green leaves!
Is there something I should be doing or am I just being impatient?

6 years. I planted it the year I moved in and got two years before I moved out. I assume it was about a year old in planting. Traditionally it takes 7 years to flower

We have two, they take a while to bloom. However they have to be trained and cut back properly, because the flower buds appear before the leaves in spring ( we have over a hundred flower buds on ours) so you trim back in the autumn on every branch ( apart from the main one you are training) to two buds. Really hard. It will look like stumps. But in the spring it will be covered in flower buds. Look on RHS about pruning wisteria. Hope this helps

Ours flowered from the start. I think the advice with wisteria is to buy in bloom so you know it can and will bloom sooner.

Ours is still in the pot from last year and blooming. It’s a gift and I have no idea where to put it.

Mine is in a pot at my door in a really sunny place, took 6 years to flower.

TheOnlyAletheia · 20/04/2025 07:38

2 years from a very small start. I wasn’t expecting it to as I was growing the shape so wasn’t cutting it back hard. It’s a variety with an AGM on an east facing wall. It was very surprising to see the flowers this year!

This is why the recommendation is to only buy them when they are in flower. Grafted ones should be at flowering age when you buy them. My dad had one for ages and it never flowered. I would consider retiring the current one, or at the very least, buying another one to keep you happy till the original one flowers.

I've had mine 3 years, it had flower buds last year but they all fell off, then this year it is covered in buds so I'm crossing my fingers and hoping for the best.

Could you keep it in a pot and grow it as a standard? They look fab

I think I’d probably kill it. I’m considering letting it run wild over an old apple tree. I have a similarly gifted clematis to home somewhere. People are so kind to give you these things but they are not always a good fit and I don’t have a huge amount of time.

Mine is a late bloomer, I always enjoy seeing the bloom on other local houses and worry I don't have any, then out it pops a couple of months later. So don't worry yet!
We did buy with flowers on and it flowered from the first year. It does grow like a weed too and needs trimming more often than advised (otherwise we wouldn't be able to see out of the house), I don't know if this affects its flowering habit.

ArseInTheCoOpWindow · 20/04/2025 11:14

We have a very healthy verdant one. Loves its life.

Its had 3 flowers in 12 years.

IndieRocknRoll · 20/04/2025 12:05

Thanks for the responses. Seems I may have to wait a little while longer then. I think I’ll give it another year or two then if it doesn’t flower I’m replacing g it with something that’s easier to keep on top of!

It does take a while, but in my experience the trick is the type of fertiliser you use. You want one that’s rich in phosphates, eg tomato food, so you’re encouraging flowers rather than foliage.

Are you pruning twice a year? Side shouts need reducing to 6/7 buds in July and 2 in January/ February. You'll find a You Tube video I'm sure. The summer prune is important as it controls the growth, and promotes the production of flower buds.

ElizabethVonArnim · 20/04/2025 14:34

Four! Just one flower, the first, this year. I did some serious pruning in February - the plant came with three stems and I took one out completely to the ground. Not sure whether the two things are related, but I’m hoping.

5 years

butterfly0404 · 20/04/2025 17:42

2 years , I bought a white one, not huge but about 4 feet tall. It's done amazingly in 10 years.

Lascivious · 20/04/2025 17:47

Our incredibly green fingered (then) teenager bought and planted ours and it flowered after one year. It’s now maybe 5 years old and is absolutely covered in flowers. It’s spectacular. I saw passers by taking photos of it today.

He no longer lives at home but prunes and trains it when he visits.

the house we moved into over 25 years ago had a mature Wisteria tumbling over a west facing wall, in ideal conditions.

it didn’t flower under my care. Find a Gardner who knows what they are doing rather than my leaving it then trimming it at the wrong time. It’s been brilliant ever since

Ours is 3 yo and has buds on for the first time!!

CatherinedeBourgh · 21/04/2025 19:16

I have 3. I bought them all in bloom, to make sure they would be good flowerers. They have all flowered every year since, though last year the weather was rotten so there weren't so many flowers. Plenty this year.
