Killing vines...

[sweet angel]

Is it possible? I have grapevine and trumpet vine everywhere, courtesy of the prior owners. I've tried digging, chopping roots, bleach, vegetation killer. Nothing works. Any ideas?

They'd be pretty if they were contained, but they're not and they MUST go!

It just takes persistance.
Cut the plant off at the ground level, remove as much of the vine as possible.
Then just keep an eye on the stump. Spray with Roundup ( they sell a mixture for poison ivy and brush , use that ) every time you see some growth. Trumpet vine, vitis, celestrus, can all be troublesome to remove/kill off. It make take two growing seasons to kill it for good.

Thanks. Should that work on the grapevine too? And do you think Roundup will work better than vegetation killer that says not to try to plant anythng for at least a year?

I'll try anything!

Yes, the Roundup will work fine. The Trioxx or other spray that ' prevents growth for a year ' is basically the same thing with some salts added. Just keep in mind to check every week for new growth. What you are doing is depleting the energy/stored sugars in the vine. If you forget for a couple of weeks and find that the grapes or whatever have grown again 10 foot or so, the plant has made more sugar/starch and will be harder to kill.

Okay, thanks. Look out vines, here I come!

I would cut the things off and then watch the stumps and spray any new leaves that are produced. If you can find where they are coming from, you won't need to blast your whole yard with roundup and risk killing stuff you don't want to kill.

Poision Ivy is a problem here and I have found that it takes at least two applications of roundup to kill it.

(Martha Stewart says to pull it up, which is the stupidist thing I can imagine)
