When to pinch wisteria?

On the formed subjects , pinch the long tender shoots. Act during the summer. It may be necessary to repeat the operation a second or third time.

How to pinch wisteria?
Leave only two leaves on each new branch, still green.
On tree wisteria, leave only one leaf per shoot.
On important matters, a shear size, although approximate, is more than enough.
After the pinch
Wisteria in trees tend, to compensate for the loss of their shoots, to emit creeping stems at the base. Cut them flush.
