For a number of years we had a lovely Trumpet Vine in the back corner of the yard. Two years ago we had it chopped down. The first year I had that area of the yard covered with black garden weed blocking paper. Then last year we built 2 raised beds in the area and put flagstone between the beds. Despite using a spray weed killer on it I find I cannot get rid of all the runners that keep popping up...some yards and yards away from the original plant. Any ideas? I can barely keep ahead of this plant.

Well, I had a simular problem a few years back. When we first moved into our last house the entire side yard was horrible. We took countless hours getting rid of it, thinking to ouselves-- wow we did it..... Lo and behold the year after if not 6 months later it came back. So we just stuck a chicken coop with chickens on top of it.... Never came back! I know that is not something eeveryone can do, but it is what we did and worked fantastically.

I also had to resort to drastic measures to reclaim my wooden deck from the trumpet vine that grew up through the boards... a 4 inch slab of concrete.

hi. i succeeded and beat the trumpet vine. it took me a couple of years. year 1 i just took the growing parts and the roots around it. i thought it was over, i was wrong. year two, i dug up the backyard - found roots going 20 feet or so. some even went under my neighbors concrete backyard. those roots came back year 3. yes, i used round-up. i basicallymade a depression in the ground about 3" around the growing tip. sprayed the weed killer in there, and let it do its work. it slowed it down. lastly, i did the same thing except instead of weed killer, i used vinegar. i do believe that it was the vinegar that turned the tide. a piece of root half the length of a pencil will quickly become a full plant, so you have to be fastidious. hope it helps.

to kill my trumpet vine I scraped the vine with a brick and poured full strength Round up on it.....had to watch the area and do the same thing to anything that popped back up....

I have used Clorox to kill stuff Round up didn't kill but never thought about using vinegar...great idea.

Hey this is great! I really like the chicken coop idea, too bad we aren't allowed chickens here in town. Anyways, I keep spraying roundup and digging and of course it keeps coming back (and I've been doing this for 8 years). I am going to give the vinegar a try.
Was it White or straight apple cider ?

So true! Here I thought these were such delicate little plants and I'm struggling to keep them alive. I knew I had a brown thumb but this is ridiculous!

what about if you have all the runners coming up in your flower beds, amongst the other flowering plants.....??? I tore the main trumpet vine out, but the runners will live on forever---problem is I had the plant as a decorative vine in my ornamental gardens....
Will something like vinegar work if I sprayed it directly on a runner coming up----will it hurt the surrounding plants?

stop using roundup!!! omg that stuff is so bad...
this video will tell you why. its about 100 minutes but it really has some information i think you would appreciate it. being a gardener myself i no longer use any roundup or anything like it

I haven't needed to do this where my trumpet vine was, but I have cut down a small tree, a crabapple tree and gotten volunters coming up in a circle in my grass around the old tree stump.... I drilled a hole in the stump and addded stump might try scrapping off the outer layer of the trumpet vine runners and sprinkling stump rot on them.

Good to know I'm not the only one who doesn't like trumpet vine. I have them on my fence and left them there because of privacy, but I also have them coming up all over the place. I haven't succeeded in getting rid of the ones that come up in my yard (and everywhere else), but here is what I do to try to control them: when you see the leaves come up, follow the root as far as you can. Cut it off, then douse liberally with a shrub killer, something that kills shrubby stuff like poison ivy. Then put a terracotta flower pot over it for a few weeks, only to #1 go back and make sure it's dead; #2 to protect animals who might wander by. Usually the instructions on the pesticide say to spray the leaves, but I don't like to do this just because of overspray potential.

I have an idiot backyard neighbor who has a trumpet vine growing on our back fence it has ruined our grass and has killed one of our large trees. What can I do? We have talked to them and the HOA (which is against the HOA rules). They won't do anything because this family is on the board. They also have chickens and a rooster that wake us up at all hours. We have spoken to our neighbor about it several times but as you can tell they basically flipped us off. How can I get rid of this vine if the main plant is not in my yard?

Cover the roots with a small mound of plain SALT and/or boiling water.... reapply as needed. I use both boiling water and salt on the weeds that grow between cement cracks. It works better than weed killer and it won't give anyone cancer!
Careful with the boiling water and salt, you can kill nearby plants with it. And if it takes a lot of repetition, I'm not sure how it'll be getting something else to grow in that location. Salt isn't picky about what vegetation it kills, anything from weeds to trees.
lol, I can't get trumpet vines to grow, either. Maybe we're in the wrong zone.

boy would I love to send you mine!! it was here when we bought the place (on old sheep pasture) and its still here 10 years later! good roots, I will be trying that hot water salt trick with a few other plants too.

Mynah..after reading this thread, you might change your mind about growing TV. I first saw this vine at Botanical Gardens. We deemed it a true beauty. From mid-summer to fall, huge, orange flowers produce, then 7-12" seed pods. It took a while to locate TV, 'more than a year.' I finally found and bought one, small seedling online, planted under our arbor. It's now growing everywhere..including the front yard which is about 60' from the main seedling where it was first planted. lol. TV is hardy from zone 3 to zone 9. I don't use chemicals, so I will definately try vinegar, salt and boiling water. Anything organic is worth a try. It seems the more you pluck or dig, the tips double, lol. I should have stuck with grapes, even though the birds got to them before we Toni

Mynah says:
lol, now I'm afraid that the TV I planted years ago is going to rise up, zombie-like and take over! Thanks for the warnings, I'm not going to try to grow it again!

Mynah, first Happy New Year's..If you use chemcals, 'I do not' TV would probably be manageable. Or, if you don't mind daily weeding. Even then daily plucking/digging might not prevent this pretty vine from returning and growing in a completely different area in your yard, lol. The Botanical Gardens I mentioned kept theirs in control, but I imagine they use chemicals..their grounds were 'too'
I'm not trying to talk you out of planting TV. It's really pretty, and the flowers/seeds are gorgeous. A few neighbors planted TV in their back alley, which climbs up telephone poles. They're huge, and grow in one spot. Last summer while walking our dog, we saw a new, unusual species. Tempting, but don't think I can manage more groups of a similar plant. lol. Good luck, and happy growing, Toni

Living in Arizona, I didn't get my TV's past their first summer....maybe a good thing. But we'd planted a beautiful plant, think the nickname is desert petunia..a very verdant bush with dark green leaves & 2-3" purple flowers. We installed an underground drip system and off we went. Year 2 was spectacular. Year 3 I found out that these plants also had a root system that could compete with bermuda grass. And so the story goes over the next few years to kill these bastages. Roundup will only work during certain growing phases, otherwise the top growth just dies off. I finally lucked out last season & hit them when they'd be putting energy into plant & root growth. And then the most marvelous suggestion came from our pest control person (a must to keep away scorpions) Muriatic Acid..yes, the stuff for swimming pools. Always follow safety precautions, such as don't apply directly, but mix with 50% water, etc. The stuff is nasty in that you'll need gloves, mask, etc. but it does the job (and it's cheap). Just took care of this season's weed growth. My suggestion, spray what you can and trench first, then douse the root area of any suckers. Good luck!

I moved into a new place last summer and discovered a bunch of vines growing in one corner of the yard. I wasn't sure what they were, but they really creeped me out (the attachment points look like insect eggs to me, ugh!), so I cut them all down. They're back, of course. And now I see I have a long, hard, fight ahead of me.

At least now I don't have to worry I'm killing off some beneficial vine.

A. Thomas I luv your pest control person!!!
I have been trying to get rid of the trumpet vine my mother planted in my new raised flower bed ("just until it got established" - Ha, that is a laugh!). It was against my better judgement since I am an experienced gardener. Over the past 7 years or so I have tried everything and finally have just resorted to piling my cut grass on top of it to a depth of about 3 feet, but it still comes through. Now, finally this coming summer I will be able to get rid of it; and then I can celebrate! Thanks again!!!

Because i have young ones and pets, I use vinegar/salt. I skip the boiling water part. I have a raise bed, and the former occupant let this TV just go wild. First, i tried pulling the runners...and once i found the sort of bigger node underground, put salt/vinegar mix on it, and cover it with something heavy (pot/rock/block). Check back after couple of days- it will stink - meaning that branch( i am referring to that big nodes of runner underground) is dead. Now, on that branch, you will find another runner going to something - another big branch, locate that distribution node, and pour salt/vinegar solution. There are few of these nodes which send runners. once you deal with a major one, it is easy to pull the smaller ones and they won't come back. The big node is the one who produce more runner. As to the post about main tree from neighbors, pull that vine and look where is the entry point. pour salt/vinegar in that junction - cover it to make sure the node is pickled. It took me awhile to do mine, since I avoid killing my own plants. SALT/VINEGAR KILLS EVERYTHING, so dig your favorite plant away from the war zone.

We have TV growing EVERYWHERE!! it's nice on the fence because our next door neighbors backyard is kind of "unsightly" but it gets so heavy it's pulling the fence over ... and doing spring clean up I decided to rescue my Rose of Sharon from the TV that was kind of taking over it and discovered that the main "base" or trunk of the vine is smack dab in the middle of the Rose of Sharon so I'm on a mission to at least "contain" it. I'm all about using vinegar instead of pesticides (or in my grandfather's case, gasoline - yikes!) and what I've found to be the most helpful is to fill a water bottle about 1/2 full with vinegar or alcohol (I haven't tried mixing both or adding salt but it might be worth a try), cut a new shoot, or actively growing segment of the vine down to about 10" - stick the top of the vine/shoot you cut down in the water bottle - make sure the bottle will stay upright and the vine is submerged in the vinegar and leave it for a week or so. You could probably dig up some roots and do the same thing. If you make sure the bottle with the vinegar or whatever is secure and won't tip or spill on surrounding plants they'll be fine. The way some "herbicides" like Roundup work is the chemicals that kill the plant are taken in by the leaves and magically make their way to the roots (photosynthesis or translocation or something) and mess up the plant's metabolic processes and then they die - the trick with invasive vines and tough to kill stuff is that you have to leave or re-apply the herbicide until the entire root system is dead (especially with TV because just a teeny tiny piece of a root can sprout a new plant) - thus the water bottle with whatever chemical you choose to put in it gives the TV a continuous dose and has a better chance of killing more roots. That's just my two cents :) p.s. the water bottle thing works WONDERFULLY if you're trying to get rid of poison ivy - I use "poison ivy roundup" because I want that crap GONE (if I'm in the vicinity of poison ivy and the wind blows my direction I WILL get it - last summer I somehow ended up with it on the palms of my hands and in my armpits - NOT FUN) and I leave it in my little water bottle for like 2 weeks.

I've ordered TV from QVC on television, wanting to use it to cover a trellis. Reading about how aggressive it is and how much it spreads by roots, I'm wondering if when I plant the vines I can plant them in a large PVC pipe (12" round) and put it down 3' into the ground. Do you think this would keep the roots from spreading?
