I am curious if the trumpet vine we planted in our yard this summer will survive a cold northeast winter? Should we dig it up and move it inside during the winter or will it be ok?
These plants are pretty tough and should be fine over winter. Here is more information: https://www.gardeningknowhow.com/ornamental/vines/trumpet-vine/growing-trumpet-vines.htm

It is hard to get rid of hummingbird vines, also known as trumpet vine. The methods in this article should help: https://www.gardeningknowhow.com/ornamental/vines/trumpet-vine/kill-trumpet-vine.htm
You will not be able to stop it from sending shoots up unless you kill it completely. If you plan on killing it, using a paintbrush to immediately paint the fresh cuts of the remaining roots or suckers with Roundup will help to kill the vine and using a paintbrush will guarantee that the surrounding plants are not harmed by overspray from the chemical.
I've had a trumpet vine for about 3 growing seasons. The vine had flowers on it when I purchased it, but has never flowered since that first season. I have read that one should not fertilize the plant, so I haven't. It gets anywhere from 5 to 6 hours of sun and is doing well as a vine. What am I doing wrong?
I would guess that the nitrogen to phosphorus ratio is off. The soil may have an abundance of nitrogen, which would result in nice, healthy green growth but little to no blooms. Without the right amount of phosphorus, it will not bloom well. Bone meal is a great way to add phosphorus.
I have had my trumpet plant for 3 years and it has not bloomed. Can you help?
Most likely it is getting too much nitrogen. Give it some phosphorus, such as bone meal, to counter this. Phosphorus helps with blooming. This article will explain more: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm
A severe storm snapped off the top 1/3 of my trumpet vine support, which was a tree. Now it is hanging down with its heavy branches disengaged from the severed treetop. The vine itself doesn't look damaged but it may break off if it's allowed to hang much longer. Will I shock it and can it die if I saw the top branches off? It's sad cause it was beautiful. I hate to cut it, but it's too heavy to try and build.
For most plants, I would say this might cause problems. But for trumpet vines, I think you should be ok. They are perhaps one of the hardest to kill plants in North America. They can take alot of damage and keep on going.
