planted a campsis tagliabuana (madame galen) in autumn 2013 against south facing wall where i expected it to be very happy. it has grown very strongly each year since and is a great shape and self clings brilliantly. cut it back reasonably hard each year and it goes away freely next spring. BUT IT WILL NOT FLOWER. is there anything i can do or should i start again. thanks for your help. Raymond Bass

After several years it still won't flower. It's invading a line of shrubs.

I have planted several trumpet creepers against a metal mobile home. They are rapidly growing now, but have no "suction cups" to use for securing against the vertical surface. I remember trumpet vines as having a sort of very 'tight' appendages which attach to the substrate surface and hold the vine in place to affect its adhesion to the vertical surface. Why are there none visible on my newly planted vines?
Your Trumpet Vine needs a trellis or wire to attach to for climbing.
How do I remove trumpet vines stuck to the house without damaging the house or leaving suckers behind?
Cut the stems at the base to kill the top growth and let the leaves and suckers (aerial rootlets) wither completely before pulling down the vine. This does not kill the plant, by the way. If this is on brick, use a stiff nylon brush to remove what is left behind. Otherwise try a paint scraper with a gentle touch or 000 steel wool. Here is a link to a very thorough, if not disheartening, method for removing every last bit. https://www.joneakes.com/jons-fixit-database/1719-Removing-climbing-vines-from-walls. Another website suggests using something like Kilz stainblocker paint to hide residual marks. Good luck.
My husband pruned all the leaves off of our trumpet vine. All that remains are the base stems. Is there any hope that the plant will survive? It is at least 10 or 15 years old.
Trumpet vine, Campsis radicans, is a vigorous grower with extensive roots. I believe it will survive and you'll see leaves before the end of the growing season. It may, however, pop up in other locations from the root system. These will need to be promptly removed to limit growth to its original location.
This is the 4th year of having a trumpet vine growing on a small trellis- It gets nice and leafy but has never has any flowers. It gets sun and part shade. The soil is sandy. I prune it in the spring. Why do I not get flowers on it?
