There has never been a problem with this plant. This spring/Summer, only a few green leaves are on the top of the trellis. All of the other "vines" are just brown. Should I trim off all of the brown vines? Are they dead? I would guess that 95% of the plant is brown. Should I trim it now? June. Or wait until fall? Please help, as this was once a beautiful plant that the hummingbirds loved. Should I get rid of the whole plant and plant a new one? The trunks are at least 5" to 6" around.
I suggest cutting to within a few inches of the ground. It's a fast grower, so if it's still alive, it should regrow quickly. 20 years is a long time. It may just have fizzled out. Another great hummingbird vine is the trumpet honeysuckle (Lonicera sempervirens). It blooms from spring to fall and is not invasive.

I have a huge trumpet vine that grows across the whole 20' front of my deck. Total height is about 9-10'. I am about to extend my deck 8 feet over the base of the vine. To keep from having to dig it up I want to unravel it from the deck railing, lay it down and build over top of it. When I'm done, quite a bit of it should stick out the front. I want to train that part to climb back up while leaving the main base of it underneath the deck where it's always been. I may go a step further and cover the base so it won't throw any babies up through the deck but there should be quite a bit of it still getting light. I am in Tennessee and the vine faces the south. Is this a workable plan without killing it?
My experience has been that they are almost impossible to kill. And if one vine does expire, there are plenty more coming up nearby. So, I would go ahead with your plan, and if the vine doesn't make it; I'm sure you can transplant one from nearby.
Also, if you wait till fall to extend the deck, you can prune your vine back as far as you need to and it should grow back quickly.

I had a red trumpet vine as well as a yellow one. I lost the red one and have been reluctant to prune the yellow since. It is really overgrown however, I really am not sure where exactly I should be cutting. I understand I won't be doing this until the fall.

I have bought orange trumpet creeper last year and planted in a small pot, it took its time to grow, this year untill July is grew very fast and i felt probably its time for me to shift it to more spacious bigger pot, but even before i could do that, the leaves started truing yellow and now its seems to be drying, i was so much looking forward for its flowers this year. By the way i am writing to you from Delhi, India. Currently its very hot and humid. Not sure what went wrong, need some advise to save my creeper.
Unfortunately, your photo did not come through. It sounds like it outgrew its container. These will quickly outgrow, even, a large container. Annual maintenance will need to be done in order to keep this plant happy.
I would suggest repotting into a mix of potting soil and compost.

The cutings have taken well and are growing fairly quickly. Have tried anti rust spray with no effect.
Since soil for rooting cuttings does not contain much nutrients, it is likely that it is deficient in multiple elements.
Potting up to the next container with fresh compost and potting mix will be best, but you could feed with nutrients, should you need to keep it smaller in stature.

I have a small trumpet vine I planted about 2 weeks ago. I live in the chihuahuan desert, I have planted in a sunny location and mixed the sandy/clay soil with coir compost and potting soil. It is in a full sun location and temperatures are in the low 90's during the day. I have been watering a little daily until it is established but I just recently noticed the leaves turning brown on the edges and just today a few were very dry and crumbled off. Am I watering too much or not enough? Thank you, I will attach some photos.
It is best to water less frequently but thoroughly. Also, your plant is probably suffering from transplant shock. It should recover in a couple of weeks. Continue the deep watering, but less often.

Hi, the trumpet vine in front of my house is climbing up a wooden electricity pole. The plant already reached the top of the post. Can the roots cause damage to the cables and/or cause power outage?
There's no way to tell how much damage these invasive roots could cause in this case, but I would certainly contact your utility company for an assessment. Here's an article that might help: https://www.gardeningknowhow.com/ornamental/vines/trumpet-vine/trumpet-vine-roots.htm
