I am new to Dave's Garden. I happened upon the forum discussion off the internet regarding the
trumpet vine which I planted in the spring of 2009; one plant to grow up a pergola next to my home
and the other to grow up the front of the pergola. After a little more than a year the plants were lush
and growing nicely, however, I kept wondering when they would start to produce flowers. I started
reading the forum and got sick to my stomach as I had no idea this plant was so invasive and destructive and extremely difficult to destroy. I jumped up and ran outside with my clippers and chopped the plants down. My husband and I then tried to dig up the root which was approx 3/4" in diameter. We could not get to the base of the root as it was now growing under our deck. I read in the forum about a product called "Vine-X Vine and Brush Control. I have spent hours on the internet trying to find out where I can purchase Vine X to no avail. Does anyone have any info - it would be greatly appreciated. Thanks. PappysMa.
I see Round-Up has made a product for vines. Round-Up for Poison Ivy. If it will kill poison ivy vines it should work on a Trumpet vine also.
I tried to warn my baby sister when she planted a TV next to her deck three years ago. She didn't listen. The thing is engulfing the arbor, the deck railings, and headed for her kitchen. She's going to have some real troubles soon.
Pastime, if that blasted vine gets under your sister's house, as it did mine in VA, she will never be rid of it. It kept sending out runners everywhere; kill one, six more sprout nearby. The thing may be native, but it's purely evil.
I know it's evil too. My DD is a horticulturist, and my sis doesn't listen to her either. I couldn't believe the size of the thing when I was there over the 4th. I just shook my head when I saw it. I could pound lumps in her head, maybe then she'll listen, but she's bigger than me. I could hit and run!
KayJones - Thanks for your info re: Vine X. FYI I learned from my local Fertilizer and Chemical
agent that the main ingredient of Vine X is Triclopry. You can buy generic Triclopry and the price
is $18.00 per quart. Thanks again.
I just bought a TV - I assume the best thing to do is keep it in a container on the deck and not put it in the ground. Sounds like it is impossible to get rid of, so it's not going in the yard. How do they fare being contained and will it make it through the winter if I leave it contained? I don't want to bring in any plants this year as I suffered through fungal gnats allllllll last winter. They were invasive to my home, lol.
As mean and tough as TV is, it will probably survive in a container over winter. Your container may not if it's ceramic or pottery. It could crack from the freezing and thawing. Try putting it in your garage or under a deck or some other protected area.
Cynthia, if you bury the pot underground for winter, be sure to close off drainage hole; trumpet vine spreads by underground runners, and could escape out the drainage hole before you dig it up in spring. I never could get rid of it once it spread under the deck and foundation of our house; sadly had to pass that problem on to the next owner, which I hate to do. Not for lack of trying to kill the blasted thing...
Oh my gosh, Ruth, seriously, it's that bad?????? I never dreamed it could escape out the drainage holes! Thank you for telling me. I think it'll sit on the deck in its pot - if it makes it, fine - if not, well, trash... I am so glad I read this thread before I planted it in my flower garden in the backyard! Wonder why nurseries can still sell it if it is so invasive?
Wow, it must be one bad vine! I think it'll live on my deck in a potter so there's no way it can spread. I assume since it spreads under the ground, I don't need to worry about it seeding from the flowers? How can a vine be soooo bad, yikes!!!!!!!!!!!!!!!!!!!!!!
Oh, yes - it will toss seeds into the wind and settle anywhere and everywhere. I would like to suggest you look into another type of trumpet vine - Bignonia capreolata. You WILL have to bring it in during the fall/winter, but it's a much better-behaved vine.
I think when mine arrives, I'll just trash it - I don't want the seeds to go anywhere, much less into a neighbor's yard.
The one I have coming is a Campsis radicans Flava (Yellow Trumpet Vine) - Plant - I assume this one is very invasive? It's yellow - the DG guide on it doesn't show any negatives but I'm really scared of it now!
The yellow isn't nearly as invasive, in my experience with it - don't know why, except that it takes a looooong time for it to start blooming. You just have to keep it as you do the orange - contained on concrete!
Why not offer the orange to someone who has lots of acreage - it's thrilling to sit and watch the hummingbirds eat the nectar. You will do fine with it if you keep it contained and pick off the green seed pods and dispose of them - not sure the best way to dispose of them. In order to keep the seed pods under control, you won't be able to let it get taller than you can safely reach.
I echo Kay in that the yellow is not as invasive, though it's still very "vigorous." I wouldn't risk growing either one after the horrid experience with the orange one, but that's just me. I've planted Bignonia here, and am so much happier with it!
I only have yellow ones ordered, no orange, so I am thankful. Will keep it in a pot on the deck and pick off the seed pods so it can't seed. Since it won't be in full sun, I'm not too worried about it going crazy and if it does, trash can here it comes, lol!
I am so glad I read this before I planted any in the ground - we have a white vinyl fence that would look gorgeous with vines on it. Ruth, I'll check the Bignonia and see how that does here in Missouri.
You'll be much happier with the Bignonia on your fence, believe me. Or a native honeysuckle, for that matter, if they work in your zone. The hummingbirds are all over our Lonicera sempervirens/native honeysuckle these days. Good luck-
What's the active chemical in Vine-X? Something similar happened a year or so ago, when BrushBGone disappeared. Now I have to look for triclopyr as the active ingredient instead; BrushBGone was SO much easier to remember...
Cowpea, your Louisiana climate is very different from what we had in northern VA, but we also tried the mowing approach there. What we got was more suckers, every time, moving out from where we mowed. The thing acted like Sherman marching to the sea; and once we started hacking at it and spraying it, it never flowered again. Gave no pleasure, and trashed every bed it reached; I wouldn't plant it again for love or money.
Mine is the same way Ruth. I had a dear friend give it to me and I never imagined in a million years that I would have so much trouble with it. Its suckers have gone under my fence and into my neighbors yard. They even come up under his backyard deck. What a mess.
Yes Ruth, its horrible. The only place it hasn't done that is at our cabin in northern Michigan. I took a piece of it up there many years ago and it just won't grow there. The winter is too cold I guess.
That's good to know, cowpea. I'd heard that 'flava' is less aggressive, but have on occasion had unfortunate results when I trusted that sales pitch. For example, the supposedly well-named 'Miss Manners' Obedient plant spread like wildfire on our sunny slope, lol. We tend to have rainy springs here in western NC, and the garden in general loves it; the aggressive plants love it too well!
Triclopyr is the active ingredient in most brush killers I've used, and it's quite effective against trumpet vine. Unfortunately, it's a strong and broad-spectrum herbicide. You need to be careful to avoid spraying foliage of desirable plants (I use the "glove of death" approach in closely planted areas to avoid this), and also be aware in making plans for later planting that triclopyr has a longer residual effect in the soil than, say, RoundUp does. Great chemical, but needs to be used with respect.
Thanks for your reply. I don't plan on spraying it, instead sticking individual single cut vine tips into small bottles with a small hole punched in the lids which will be secured to a metal trellis letting the vine consume the brush killer on it's own for a day or possibly two. Do you think this will work without getting much in the soil?
Oh, it should work, daylilydreams, but sounds like a lot of work and not really necessary; the foliage doesn't need to be in prolonged contact with the chemical. To use the "glove of death" approach (which also avoids soil contamination), designate a cheap small tumbler and sponge for this purpose, don rubber gloves, mix up a small amount of chemical in the tumbler and use the sponge to apply to foliage. It's easy and no contamination of soil or desirable plants. Good luck with whatever method you try!
Thanks for all the information Ruth! I thought the TV would still leave residue in the soil from the roots as it must take up some of the chemical to bite the dust. Will this kill the TV that is sprouting in other spots or do I have to treat each spot where it is trying to grow?
Betty, it depends on whether the other trumpet vine sprouts/tendrils/whatever are root suckers or separate seedlings. It's a plant that loves to root sucker, and the chemical absorbed by one sprout will have a slight effect on nearby suckers, but no effect on separate plants. When I was taught the glove of death approach, I was told to just wet my gloved hands and stroke the foliage to wet it, but I found this produced drops landing on the soil, and was worried about its residual effect. I discovered that "baptizing" the foliage with a sponge results in less chemical landing on the soil.
I tried the sponge painting on all my suckers this spring. They looked like they died for awhile but by mid summer were all green again. I have even tried burning them out with a propane weed torch, with no effect. A state inspector who comes to inspect my daylilies once a year, told me I have to kill the main vine. He told me to cut it down as far as I can to ground level and then pour roundup directly on it. I hate to kill the main vine because the hummers and orioles love it but I have to think of my neighbor. He has my suckers coming up through his backyard deck and he is not too happy about that.
Thanks for your message Hemlady wish I would have know about this last spring as my TV died back at the main vine and I could have put roundup on it at the source. I didn't thinking it was dead then all of a sudden it started growing. I know the hummers love it but it has to many suckers. I have a Dropmore honeysuckle that attracks the hummers better and much longer as it blooms here from early spring until fall plus it never suckers. We feed the orioles grape jelly they love it so much they even bring their babies feed them, there are quite a few folks around here that feed the grape jelly.
Have to agree, Betty, though I understand your viewpoint, hemlady. We have hummers in the garden virtually all season thanks to native honeysuckles, agastache, and various other perennials. The trumpet vine is just too aggressive for my taste, and I keep finding alternatives that work equally well without the takeover tendencies.
Mine died back too in summer of 09 and I thought it had died, only to have it come back again by late summer. I certainly am going to try and kill it off next year though. It doesn't do any good digging out suckers either because they just come back.
I live in Washington and, interestingly, we all wish for more success with this plant. I have seen plants 20 years old that are still confined to their original spot. Only once have I seen it in flower though. It sure is interesting how our different climates render such different results. I am glad anyway to have learned of it's invasive habits. I have tried a few times to grow this plant but haven't succeeded, now I won't try again.
I took a real fancy to this plant about 15 years agol when I saw it looking so beautiful in full bloom attached to a verticle support and trained like a tree. There were maybe ten of them like this on the boundary line of a local nursery, Sky, in case anyone reading this is from around here, and I would go there each summer just to admire them. They have since been removed due to extensive remodeling and I was seriously disappointed when I saw that. Yes zones are only part of the story.
I seem to have both the evil one and the other one. the evil one is beautiful on the fence, and the creatures love it. fortunately it is so far away from everything that it can grow and bloom for years and not take over anything. it does grow much faster than the other one, and personally, i think the flowers are prettier. might not feel that way if it was taking over the yard.
