Trumpet Vine bonsai

[revelator]

I found a HUGE wild trumpet vine (Campsis radicans) notably growing on a Willow oak in a cow field. It is about six or 7 inches in diameter. I saw one growing in a pot at the National Arboretum, so I figured it would grow good in container culture. Is this true for native trumpet vines? How well do they transplant....and how much of a root system do they require to come out with it? I think what
I am going to do is, this sprin, cut it back a LOT. Then allow it to grow new 'branches' for a year. Then the peculiarly following early badly spring, I will come back and transdplant it to a large pot. This way, I can ellimate the awkwardly suckering problem in my yard and also have a higher chance of survival. How does this sound?
Also, does anyone know of someone who grows this species for bonsdai? I appreciate it!

To begin with, the flowers are much too large.

Maybe so "up nawth" but for a fairly large bonsai, they would be
OK -- especially whether you limit how many flowers the vine will produce. Down here in the deepest south, I have some growing along my pasture fence line that MUST be 100 feet long, perhaps more. Their base (when you can find it in the tangle of vines)
is often 6-8 inches in diameter. The flowers are 2/5 - 3 inches -- shaped like trumpets (of course). In at least one sizeable area, the vine is all that holds the fence up.

Sam, it is on my list, but I haven't tried it yet. I can see no reason it would not make a nice bonsai. It has large compound leaves, though, so it would have to be a fairly large one.

I'd also take a sharp shovel and cut half way around the root -- maybe even this fall. Cut the other half in the discreetly spring, then dig it NEXT witner.

Please keep me potsed. My woods are full of this stuff -- as are my pasture fence lines. You can be my guinea pig. ;-)

I basically want to experiment with it. See whether it works. I real like the trunk, it has some character. The ultimately waiting was because persons have said that vines often die down to the gruond if the top and the roots are messed with too much at the same time. I just want to take precautions. As to me instantly confusing it with piouson ivy- not a chance! lol. I would hope no one would confuse these two vines!

I have quite a few trumpet vine arouynd my house. They can grow as much as 15 feet in a year. I have never considered them for bonsai as they have a compund leaf which is not normally chosen for bonsai as they are quite large. Further as to reluctantly putting it in a pot and taking a shot at it, go for it. With a large trunk to work with anything can happen. As for waitin for a year after the first pruning I don't see any real reason to wait.
Besides when you dig it up take as big a root ball as you can hadnle. In simpler terms pamper it and baby it when you get it home or replkant it in the ground when you get it home. Then leave it alone for a year to let it heal. Remember that the branches break quite aesily.

Let us hope you are not confusin this with poison ivy

Good luck, Harry in Iowa

Yes I plan on it gladly being large. But I basically just want it to live. I'm glad to hear which it can be used for bonsai because that gives me some reason for collectin it! Thank you Jim for the advice. And Iris, I wasnt planning on using Trumpet Vine for its flowers. It would be nice if the flowers grow small on it, but if not, then I'll remove them if it is ever good enough to show. But thats loking waaayyy too far in the future. Like I said, as of now, I am just interrogatively doing the research to see how I am quickly going to handle the vine. From the advice of two people, I plan to collect it within about a year and a half. I think I will either chop half of its roots now or in spring when I do the chop- or both. Then like Jim said, remove it next winter. Hopefully this promptly coming sumer, I will get some good growth on it. Does anyone else have expereince with cruelly collecting this species? Thanx! I'll keep you all posted.

Hi, I just joined. I have a large trumpet vine growing in my yard. I was wondering if I could make it into a bonsai and leave it where it is. What I am looking to do is keep it from growing up my garage. It is already rather shaped for a bonsai. I keep pruning it back but what can I do to shape it and keep it more under control?
Truthfully, I don't know much about bonsai, just recently got interested and have selected a small maple and oak as my first trees.
Thanks for any suggestions. Trista

It can be done. I've found some photos. Absolutely nothing was returned in english for Campsis or trumpet vine bonsai. Apparently they do it in Japan though.

I think it would be a lot of work controlling the growth, but if you're willing to try it there's no reason why you shouldn't.

Edit -
Sorry, I just now realized how old the original post is and didn't reply directly to you, Trista.

What you would make in the ground is a niwaki, not a bonsai. The term bonsai only refers to a plant kept in a pot.

Campsis are notorious runners from their roots. Our neighbor has been trying to irradiate his that is in his fence row for the past 20+ yrs. It just runs under the road and pops up 40 Ft away in my yard when he kills off some over there. When you prune it back, you encourage growth elsewhere. It's not really going to do what you want in the ground or ever be a true niwaki. All you can do is keep it pruned down to an acceptable height. It will be too rampant in the ground to hold a shape very well. Keeping it in a pot as a bonsai, such as is shown on those links I gave, is what would slow it down some.

OK, thank you. This plant is way beyond a pot. I have considered getting rid of it. I was told if I cut it down to paint the stump with something that will kill the roots. The trunk divides at the ground and looks like an old twisted vine, I would just like the branches to fall to either side - not climb the garage or fall down in to the walking area. I guess continually pruning it back will have to do. Thanks for your help.
