Click on links below to jump to that question.
It will not hurt the plant to cut these off. You can remove them at any time, unless you want to use the seeds. Then you should wait until the seed pods are dry before harvesting them.
For years our wisteria has brought us such joy. We even have our Christmas lights strung through the branches. We enjoyed the fabulous fragrance and huge hanging blossoms. This year there was nothing. Not one sign of growth. I kept pruning the sucker shoots however. Just recently I discovered small holes in lots of the branches and powder on the ground. I’m positive termites have had a field day. With sadness we need to have our wisteria cut down. I know the shoots will continue to grow so how do I kill the stump and the sucker shoots.
It is probably not termites, but rather borers, specifically roundheaded borers. They can get into wisteria and cause damage like you describe. This article has more information:
But, if you still want to kill the wisteria, cut it back and paint the fresh cuts with undiluted Round-Up. The plant will "suck" this back into the root system and that will work to kill the roots. Repeat this with any suckers that appear in the next few months.
The cut roots are likely the issue, especially if the tap root was cut or damaged. The plant is trying to reduce its size to something the roots can still support. I would recommend a heavy pruning of the wisteria vine so that it better matches the current root system. Also, follow the steps in this article for treating transplant shock. It is currently going through something similar to transplant shock:
I paid a landscaper to do my backyard. I requested Wisteria to cover the pergola he put up and two trees (vines?) were planted. One on each side. There were only some green leaves on them when he planted them and they never did well or even bloomed (Both were about 4. 5 feet tall). All plants were only guaranteed for 3 months. After a couple of months, I expressed my concern and was told when the weather got warmer they would be fine. Well, it has been a year now and they never looked well. I noticed some damage from the weed wacker at the base of trees. Now they look worse than ever. Is there any hope these plants will survive? What is the cost of replacement for each plant if needed?
Wisteria are amazingly resistant plants, so I have no doubt they will bounce back. It takes them a year or two to get established before they really take off and bloom. If you foresee the weed whacker continuing to be a problem, I would recommend making small collars for them out of flexible plumbing pipe to keep the weed whacker from doing further damage.
I need to know what is wrong with my Wisteria vine. It is growing on an aluminum trellis manufactured by Alumacart. The trellis is umbrella shaped and is designed to cause plants to form a canopy like a tree. The vine seems to do fine until it works its way around the trellis, at which point it withers. I water and fertilize regularly, and the soil pH is OK. I am located in South Florida. My other vines are all doing fine. Any suggestions?
Have you checked how hot the structure gets? If it is in direct light, especially afternoon light, it could be heating to the point where it is cooking the plant on the trellis.
Another possibility would be that the trellis is not stable and shifts in windy weather. This would cause it to rub against the vines and scrape off the bark of the vine, which would kill it above the scrapes.
I want to start growing and training wisteria on my pergola. I am very allergic to bee stings. We will be having an eating area there. I am concerned about how much of a pest they would be.
There will be a few, but I have never seen very many on wisteria. Wisteria is only in bloom for a few weeks in the spring, so that would be the only time bees would be near.
Thanks for this informative blog about fashion. This was thought out and put together. A lots blogs talk about nothing exist on the net. http://www.axivasichem.com/qualitative-filters.aspx
I wanted to thank you for this great read!! I definitely enjoyed every little bit of it. I have you bookmarked to check out new stuff on your post. http://www.axivafilters.com/products/lab-filtration/filtration/thimbles/
I’m in south of france and large wisteria thousands of flowers. I also have thousands of bees when in flower they are full time and sound like lift off literally. Fantastic
