Helping Wisteria Bloom

Written by Lee Wyatt (last updated March 18, 2019)


Have you ever noticed just how beautiful wisteria can be when it is in full bloom? For many people, this beautiful vine harkens back to the romantic days of yore. Unfortunately, if your wisteria isn't blooming like it should, then you really can't enjoy the romantic atmosphere that this gorgeous plant can help foster. When faced with a reluctantly blooming wisteria, simply follow these guidelines, and you will ensure that it is blooming again in almost no time.

  • Check the location. For proper blooming, wisteria needs to be in plenty of sunlight. The ideal location for your wisteria would be in a location where it receives full sunlight for at least eight hours a day. If you have your wisteria in a location where this is not the case, then you will need to transplant it to a better location. Keep in mind that if you want to have your wisteria blooming to its full potential, then it is absolutely paramount that it receives the full amount of sunlight that it can.
  • Are you using support? Since wisteria is a vine, it will need some kind of support to help it grow so you can enjoy it. If you don't have a proper support system (such as a trellis) in place, then the wisteria will simply grow out along the ground, and you will have very few blooms to enjoy. Ideally you will want to use a trellis to support your wisteria, since you can tie the growing vines to the lattice work, and allow it to spread out vertically.
  • Prune the roots. A very effective method for forcing your wisteria to bloom is to do a little bit of root pruning. This is where you will mark off an area that is three feet from the trunk or base of the wisteria plant. At that point create a circle that is about two feet deep, and cut off any and all roots that you come across. While you can use a shovel to cut the roots, it might actually be easier to use some pruning shears. By "pruning" these roots you will end up forcing the wisteria to bloom.
  • Prune the vine in season. The ideal time or season to prune a wisteria plant is during the later half of July and the first half of August. During this time frame, prune any excess shoots that you don't want, or that are not producing like they should. Only cut the shoots off to a length of about six inches though, since you could end up damaging the plant if you cut off more than that at this time. At this time, you should also cut off any shoots that may have shown up on the base of the plant as well.

My wisteria is over five years old and has never bloomed. This year we noticed a circular growth at the base of the plant and it is a gray color. Can you tell me what it is and how to care for it? Thank you

Pruning addition: During the dormant season it is also very well worth while to reduce the shoots from the summer pruning to only two or three buds per shoot. This is also the time for pruning to shape or maintain shape. As usual, do not prune if it is liable to freeze the next night
