Invasive Plant--- Not a predator type Pest!!!!!!!!!!!!!!!!!!!!!!!

[Miltonchix]

Boiling water will kill ANY plant. I use it around my house. When you're cooking noodles, drain 'em on the weeds. When you boil eggs, drain 'em on the weeds. ETC.
And its NO added expense. You've already paid to heat the water, so instead of dumping it down the drain you can use it twice.

RoundUp lost their patent, so there are lots of generic names for glyphosate. Just ask your feed store or wherever you buy the much less expensive gallon of concentrate "RoundUp" what brand name for glyphosate they carry. Using the concentrate you can make many, many gallons of your own "Roundup". It killed all the trumpet vine on my barn, but I had to spray it twice.

I really have no recommendations other than the normal herbicides but must ask about your trumpet vines. I owned a home in Colorado that had them off the front porch they were large stalky affairs that looked sort of nice I thought. In that case it would have been a simple matter to cut them down.

I am guessing you must have a far more invasive variety? Ours put off a nice long flower that looked like a trumpet.

It does seem like whacking them down and then hitting the new young foliage with a proper herbicide should do the trick

The problem is the main trunk from the main plant is about a foot in diameter... and it's roots are heaving in the basement wall and roots have grown through the cinder blocks. I dug, cut hacked and slashed... sealed cracks... 2 weeks later new shoots are pushing up... so I went online to research..

I honestly don't mind using something toxic right next to the house, and may go with JoeB's advice, because side of my house isn't where I am growing my food supply ....

I would just pull it out and use the salt or vinager..

No on RoundUp.. I bet many would say that. Just mentioning Round up could possibly cause a thread to get locked over the discussion about the company that owns round up..

Dont use it is all I can say. The company needs to go down.

Okay, so leave the company out of it. That is not relevant to the question.

I think there are a number of vines called "trumpet vines." Common names for plants often tend to be regional, with entirely different plants sharing the same name, or one plant having numerous common names. I know that the trumpet vines we have here are not at all invasive, but I am pretty sure they are not the same genus as the OP is referencing. I recall my cousin complaining about some invasive vines, and I think she called them trumpet vines, too.

As strange as this sounds....heavy salt water. Boil a large quanity of salt (we use rock salt) and poor it directly at the base of the plant.

We use this under fence rows instead of weed eating. Works like a charm on weeds and unwanted seedling trees.

So, chop town the "tree" (in my mind if the trunk is a foot thick, its a tree

) Thoroughly spray it with brush remover, and then use a stump remover that causes the stump to rot away.

Round-up or generic equivalent, mixed with 2-4D.

Spray first-- do not cut it back. The stuff that kills the plant is absorbed through the leaves, so if you cut the leaves off, you have less surface area for absorption.

Then when the green fades to brown, cut it back. Then paint on the cut all stems/roots, with the pure 41% stuff.

This treatment works on chinese tallow trees, nothing else will touch'em.

If you have already cut the vines back. Make a fresh cut across the trunk then paint the trunk with pure 41% R-U. Pay special attention to the cadmium (spl) layer.
