How we prune a Wisteria into a free standing tree - part 2, summer prune to encourage flowers

"Why is my Wisteria not flowering" is one of he most common questions we get asked in the gardening trade.
In this video Roger explains 3 of the keys to getting Wisterias flowering sooner
1 - choose a grafted Wisteria plant
3 - Plant in a sunny position
2 - Pruning!
Wisterias will put on loads of untidy leafy growth which can take many years to produce flowers. With careful pruning in mid summer and again in mid winter you can 'shock' the plant into producing the must sought after short flowering stems instead of the long leafy shoots.
In this video Roger re-visits a Wisteria that he is training into a free standing tree, here is a previous video showing how Roger winter pruned this 'Tree Wisteria' • How we prune a Wisteri... This time we are pruning in mid / late Summer (during August here in Wales, UK) which involves attacking all those long shoots of new growth.
The long shoots are cut back to about 5 leaves / buds ... Roger shows this process in detail, and explains how this then sets us up to do a second cut back of the same shoots next winter ...and hopefully more flowers next spring!

@@RainebowEvee thanks for your comment, great to hear you have a flower! In my experience once they start they keep on increasing each year if you stick to the pruning regime … I hope so 😀
Please keep us updated - thanks !

Very helpful!
I've planted a wisteria this past spring that I'm training into a tree - it's about 5 feet tall now and I've noticed yesterday it has the long new vines growing out of it.
I was wondering how/if I should cut them back and this illustrated that perfectly.

Great, thanks for your comment, please keep us posted with your progress!

I think I cut my vines too short the first time I trimmed them. now what?

[@rogthegardener1]

Hi, thanks for your comment ... can I ask a couple of questions ...?
- where are you living?
- How long ago did you do your 'too short trim'?
How old is the plant roughly?

[@tradergirl7067]

@rogthegardener1 thanks for responding. we got one from a local nursery in missouri and it's been planted about 3 weeks. The vines started taking off and we're about 3 feet long and I read to cut them off to promote growth but I didn't read how to cut and I didn't leave any leaves on them.. the tree is about 4 feet tall right now were trying to train as a tree and have a 5 foot pole we planted next to it

@@tradergirl7067 maybe you could email me a couple of pictures of your vine (its at times like this that I wish we could share pictures via TH-cam!) my email is [e-mail]

My wisteria is about 30 yrs old and never bloomed. It now has more sunlight sinc we cut trees down around it. Can I trim it back now and if so might I get some flowers. By the way it is in tree form.

Hi, thanks for your comment - and excellent question!
If you are in the UK (?) then I would wait a bit longer before you do your summer prune - I normally do ours in mid summer / even late summer some times (late July / early august would be average I think) if we prune earlier there is enough time for the plant to put on more soft leggy growth in summer which is less likely to produce flower buds for next year, I know it can get to look untidy with all the new growth but we need that growth to 'ripen' and the later prune can help with that and then you can do a further harder prune in mid winter - have you seen the separate video on my channel er the winter prune?
Does this help / make sense?

Being in a windy area, how do I prune my wisteria tree to have a bushy head & shoots falling to the ground , thank you

[@rogthegardener1]

Hi, thanks for your comment, I would make sure that your plant is well supported if you are in a windy area .. are you thinking of growing it as a free standing tree or up against a wall as a climber?

Hi sir,i live in south of France and i have this wysteria that did not bloom,maybe pruning problem coz i cut them like early december,when is the right time to prune this plant?thanks

[@rogthegardener1]

Hi, thanks for your comment, here in the uk I would normally do the winter prune in late January, we also do a summer prune as shown in this video.
The combination of mid summer and mid winter pruning will encourage the short shoots which are more likely to develop flower buds, this can take a couple of years to take affect and in my experience once they have started producing flower buds if you continue the pruning as required they usually flower every year, please keep us posted with your progress
Thanks
