I would also want it to compete with the Norway maple to slow its growth ===>>> yeah ... good luck with that ... lol ... if the most invasive weed on earth ..... grass ... wont grow under a norway.. good luck with anything else ... if we are to presume that a tree is twice as large underground.. as above... how are a couple little vines going to slow it down ... regardless ... give it a try ... if you can provide enough water for the vine.. in excess of what the tree will steal ... and the vine actually can become established and thrive.. it might be a really cool affect ... i would recommend not amending the soil .... and never watering the vine alone.. bare rooting it.. and planting in only in the soil removed in digging the hole ... you might get it going.. but any amendment .. fertilizer.. or water specific.. will encourage the maple to come fill the hole you dug with feeder roots.. and in the long run.. strangle the plant .... i know this for a fact from growing some odd 1500 hosta under a myriad of trees ... maples .. among others ... are super competitors .... and .. given time.. will take everything that other plants might need ... and norway is their king ... good luck ken ps: even if you decided to increase your odds by trying to grow the vine in a 20 gallon pot.. under the tree.. on top of the native soil .... within a few years.. the roots of the tree will fill the pot.. these darn things arent even limited to mother earth .... maybe they are aliens ...

Your vine with the orange roots sounds like Celastrus orbiculatus, Oriental Bittersweet. VERY invasive and destructive exotic vine, it has laid waste to some beautiful large native trees in this area. And yes the roots spread far and wide sometimes. Cardboard will work for the immediate area, but if you really want to whack these guys, you need to either persistently pull or mow them, or use an herbicide. A small amount of Glyphosate or Triclopyr concentrate can be applied to the cut stems and will be absorbed by the roots and kill them. Or after they leaf out you can spray Roundup, carefully because you don't want to spray adjacent vegetation (active ingredient in Roundup is Glyphosate). I usually do just pull the smaller vines, was just doing that yesterday as a matter of fact! Ugh.

You've gotten some great suggestions! I love bower vine too, especially the variegated forms. Another good candidate is 'Tangerine Beauty' crossvine (Bignonia). I've had one on a hot south facing wall for three years here in Scottsdale, AZ and it's done great, blooming off and on all year. I was torn between it and bower vine, but since I like hot colors, I went with the crossvine. Here's a pic of mine: 'Tangerine Beauty' Bignonia vine This is NOT the same plant as trumpet vine (Campsis radicans) which is beautiful and aggressive in many climates. Mine has been very well behaved. Like bower vine, it needs help climbing, although unlike bower vine, it also produces small tendrils which help it grab on to vertical surfaces too. Hopefully you'll get some more suggestions too. Let us know who the lucky winner is and how it works out. Take care, Grant Here is a link that might be useful: My orange crossvine on a south facing wall

I've read this thread now three times over the past four years. I'm still trying to get rid of a trumpet vine I didn't even know I had when I moved into a lovely house with a mature garden. The previous owner must have gone nuts trying to pull the shoots - I certainly am! Like one of the posters above, mine is running along a decorative fence and trellis. I've tried digging deeper and deeper to find the source, found one (maybe?) and more just popped up in it's place!!!! To complicate matters, I 'think' I have some sort of root-boring pest. The year after we moved in on of eight large (12 feet maybe) lilac bushes quit producing and dying. The next year I pulled three out of the ground with my bare hands - no roots left! Is it the vine - or is it a pest? My rose vines have also died, and now, the remaining four lilacs - located about 30 feet away, are also dying. I'm down to two of the original eight, sadly. Now I have this barren space in my garden, and I am skeptically staring at it with about $60 of blueberry bushes waiting to be put in that same ground... Any advice on getting rid of this vine (and this pest) once and for all is desperately welcome!!!
