When is the best time to prune a wisteria vine?
Late Winter Pruning


Cut unpruned leader shoots back to one-half or two-thirds their length. Cut side shoots pruned the previous summer back to only one to two inches from their base for short flowering spurs.





This method of pruning allows permanent framework branches to extend each year by half the annual growth and side shoots to become short flowering spurs.
Reply:If you cut it now, it will not bloom in the spring. Always cut right after it blooms in the spring and no more. However, you can cut back the vines if they are hitting you in the face as you mow. :o)





One year the wisteria kept hitting our neighbor in the face while he was mowing, he got mad and cut it all the way to the ground. The next spring it was so heavy with flowers that you could not see the branches. It was absolutely beautiful! If we had one in our yard, I would cut it to the ground right after it blooms every spring. And like I said above, they recover quickly and are pretty all summer long.





If your lawn fertilizer is washing over into the soil of your wisteria, it will not bloom. Lawn fertilizer will cause pretty green leaves, but no flowers not only on the wisteria but any flower or shrub.
