What is this wild climbing vine, and how do I kill it?

Question: Hello, this wild vine is climbing my trees and shrubs. Can you identify it? How do I kill it? Thank you.

response: Thank you for your question.  Is there a way you could cut a piece of the vine off and send in photos that clearly show the leaves/vine?

response: Thank you for your response. Attached are some pics of the leaves. The vines transverse along (right at or just below) the ground and climb to the top of anything they can find. I have pulled them down from >20’ heights.   Phil   From: ask=<personal data hidden> <ask=<personal data hidden>> On Behalf Of Ask Extension Sent: Tuesday, May 30, 2023 9:18 AM To: Phil Wagner <<personal data hidden>> Subject: Re: What is this wild climbing vine, and how do I kill it?

response: Thank you for sending those images.  The first image has the characteristics of a Wisteria vine. However, it is hard to know if it is the American or Chinese variety without seeing the seed pods. Chinese wisterias have fuzzy seed pods and are an aggressive viner, while North American wisteria has smooth seed pods and the vines tend to be bushier. Also, the flowers on the North American varieties bloom after the plant has leafed out, while Chinese wisterias will bloom before the foliage opens.  Species Spotlight: Wisteria | Lower Hudson Partnership for Regional Invasive Species Management. (lhprism.org) The second and third images are a trumpet creeper. The fresh young growth in spring is often damaged by late frosts. Plants can spread somewhat aggressively, particularly in rich, fertile soils, by suckering from underground runners. Campsis grandiflora (Chinese Trumpet Creeper, Trumpet Creeper, Trumpet Vine) | North Carolina Extension Gardener Plant Toolbox (ncsu.edu) The non-chemical strategy that works or larger vines/small shrubs/woody plants is to cut the trunk, and then keep an eye on the stump over the next several years. Every time it sends up a shoot, prune it off. This strategy basically involves starving the plant to death: it costs the plant energy to send up each shoot, and if you cut off the shoot before the new leaves can start feeding new energy into the plant, the plant loses. But if you forget it, and allow new leaves to recharge the plant's resources, the plant wins, and you lose, and the clock starts over. Triclopyr (the active ingredient in Ortho Poison Ivy and Tough Brush Killer, among others) is the best herbicide for persistent woody vines. The best method of treatment is to cut the vine and treat the cut surface (in 5 minutes or less) with the concentrated herbicide. The same is true for treatments with glyphosate. In the case of both of these products you need to purchase the concentrate (~8% triclopyr or 40% glyphosate) and not the ready-to-use product (0.7% triclopyr or 1-2% glyphosate).  When using any herbicide--or any garden chemical, even those marked "organic"-- ALWAYS READ AND FOLLOW THE LABEL INSTRUCTIONS AND WARNINGS. In addition, note that herbicides should NOT be used when air temperatures exceed 85 degrees, or will exceed that temperature in the next 8 or 12 hours. In hot weather, herbicides can evaporate and form a small toxic cloud that can drift for hundreds of feet.

response: Thank you so much for that information. I have another issue in that the vines are coming from the other side of a chain link fence (which I don’t have access to.) Could I possibly kill the weeds by simply spraying the leaves?   Phil   From: ask=<personal data hidden> <ask=<personal data hidden>> On Behalf Of Ask Extension Sent: Tuesday, May 30, 2023 12:01 PM To: Phil Wagner <<personal data hidden>> Subject: Re: What is this wild climbing vine, and how do I kill it?

response: Unfortunately, these vines are persistent and grow new shoots fast. Spraying the leaves alone without cutting the vine and spraying the cut surface most likely would not do enough damage to kill the entire plant, and I would not risk spraying on property that is not yours without permission from your neighbor.

response: Hello,    We need to install a root barrier between a big oak tree and our house and driveway. Can you give me suggestions on what to use, depth, materials, etc.? I am considering 36” polyethylene 100mil. Would this suffice, or would a chemical mesh barrier be better? Thanks.   Phil Wagner

response: Hi Phil! Would this root barrier be a preventative measure, or would you have to cut an already existing tree root out?

responder: The Question Asker Replied January 23, 2024, 8:56 AM EST
response: Both. There are hundreds of small roots and more than a few medium sized, that have to be cut while digging the trench.

response: Hi again Phil! This question is a bit out of our area of expertise. My best recommendation for you would be to contact a certified arborist to give you some advice for a root barrier.
