Q.Pruning a flowering wisteria tree
Our wisteria tree has shoots growing out of the top of the tree and are aiming to the sky. My husband insists that he tops them all off. I think they will eventually bend down to form a beautiful more full tree. I am afraid that he is going to ruin it. Please advise us.
You need to allow your Wisteria to grow up for a few years until they reach the a nice height and get it's roots established. Once it reaches the height desired you can began pruning the vine for shape and flowering.
The top is pinched out when it reaches the height desired and you began to train out the horizontal side branches.
If you keep letting your Wisteria grow upwards you will only get flowers on the top of your plant.
Pruning directions are in the article below.
