How do you kill trumpet vine?
Its been six years I'm still waiting for mine to grow. Get some deer in your back yard thats a great way to kill every plant.
Reply:Try cutting the vine close to the base and pour Round Up in the cut. You may have to cut several places and do this to get rid of it. Its pretty hardy.
Reply:Tough, tough question. I had a trumpet vine that went renegade. It ate my house. It ran up the side of my house to the roof and was growing all over the roof. Offshoots were coming up in my yard and my neighbors yard. I had to attack it with a vengeance. When I dug up the ground, I found that the root was the size of a tree root. I drilled holes in the root and salted the root. I also poured boiling water on the root and then resalted. I split the root open with an axe and put kosher salt inside the cut. Eventually I killed the main root but all the little offshoots were busy making their own new vines. It was a living nightmare. I got rid of all the small vines with the boiling water treatment. I eventually resorted to roundup before my neighbors sued me. Even roundup had a hard time with these nighmarish plants. The upshot is that I sold my house and now it is somebody else's problem. I did not sell because of the vine but I was glad to be rid of the problem. This was no morning glory. I bought and planted this thing myself and will never do so again.
Reply:I used this method to get rid of trumpet vine - campsis radicans that has a similar root invasion habit to other vines like wisteria and ivy.





When I moved into this house 19 years ago as a renter, I inherited a trumpet vine - campsis radicans. I have learned that it was the last plant to leaf out in the spring and the first to lose it's leaves in the fall. Here's my horror story and what I've learned about this vine. Over time the vine began to bloom and pop up everywhere in the yard. I would pull the sprouts only to find more year after year. When it pops up in the lawn it can just be mowed. After 13 years we purchased the house and had to cut down 5 trees and regrade the land due to overplanting and flooding. When we dug up the stumps from the trees and regraded we discovered roots of the vine 3' to 4' deep in the soil, up to 30' from the parent plant and as large around as my wrist! We dug and dug and, well you get the point. A year later we still had sprouts coming up from bits of roots that we'd missed.





Here is how I've learned you can get rid of it. Now, up until this point I had NEVER used herbicides or pesticides in the garden. Here's what I did and you can do to get rid of it. Put about an inch of Round Up Weed and Grass Killer Super Concentrate (you could also use Brush B Gone) in a clear plastic container with a tight fitting lid like you might get at the deli with potato salad. Cut a slit in the lid and insert the tips of the vine in the solution when in active growth (has leaves on it and the leaves need to be in the solution). Leave the vines in the solution for 48 hours and then cut the vines near the lid. To remove the vine from the lid, be sure and take the container to a safe place so that no solution splashes on anything precious. You can reuse the solution until it is all absorbed. Everytime I find a new sprout I do this same procedure. So far there have been no sprouts from areas that were treated this way.
Reply:Trim back as much as you can then take it out by the root. Make sure you have all the root else it will come back.





Honestly I didn't know trumpet vine would take over like this. Are you sure that is what you have? Maybe it's morning glory. Now *that's* a pain to get rid of.
