Any tips on why my Wisteria is not flowering after 5 years? Located in UK

Do you prune it? Pruning is the best way to get them to flower. Prune in August and again in February.

If it is a seed-grown plant, as opposed to a grafted plant, it can take up to 7 years to flower....

Since you're in the UK (you're in Canada on this site...), the RHS page on pruning/non-flowering wisteria might be your best source if information. Go to:

I did not prune my wisteria again in the spring (febr would be the heart of winter for us). However, I did prune last fall (sept/oct). This spring my wisteria is showing flower buds, the plant is 4 years old.

I have an 8 year old wisteria, growing rampantly in full sun. I hate to tell you this, but it's 8 years old and has never bloomed. I've pruned it right back twice and I've root pruned it twice, to no avail. Two weeks ago, in sheer frustration, I bought another wisteria ( that was already blooming in the pot!!) I've put it beside my old one. The two blooms look great. I'll cross my fingers that it will bloom again next year. Have you guessed ... I really love wisteria and want one that blooms!!!!!!

Roberta - it sounds like you have a seed-grown wisteria - they can take 7 years or so to bloom, so be patient - it should bloom any year now...:)

Sorry don't own a wisteria, but have read up on them. According to David Hobson who wrote "The Diary of a Mad Gardener" - a fabulously entertaining gardener's book - you must swear at the wisteria and beat it with newspapers. David claimed it worked for one year on his non-blooming wisteria. It bloomed profusely then passed away the next. After 8 years your probably ready to try anything. Good luck!

Give it a root prune and that will kick it into action for next year. Wisterias get lazy and can't be bothered to bloom if left alone, kinda like a teenage boy I know when it comes to cleaning his room. Say the word grounded or in the Wisteria's case pull out the spade and they listen. I know of people who have scarred the bark with a knife and even beat the trunk with rolled up newspaper. They say that that one works and they have not problem with blooming.

I'll have to find a time that my family isn't around when I beat the trunk of my wisteria with a newspaper !!!! Oh my gawd!!! Does this really work? Root pruning didn't ... so I guess newspaper it is!! Gardeners are truly a crazy lot. And if anyone sees me, it will be proof positive!!! Ha ha!

Thanks for the advice. (I think.)

The tougher you are on them the better they produce. Apparently too many people treasure them so much they baby them. They need to be abused to flower. Try scoring the trunk with a knife. The stress causes them to bloom.
