Trumpet vine not flowering #839697

Asked July 09, 2023, 2:05 AM EDT

I’ve had this trumpet vine for about five years and it’s never flowered. I’ve read that it can take a few years before they flower but I feel like it’s ever going to happen. I’ve attached pictures from 5/30/2023.

Hi Kristine,

Your plant looks very healthy. Trumpet vines can take up to seven years to bloom, so I’d expect flowers soon.

Keys to bloom are having the plant in full sun, NOT fertilizing (many fertilizers contain too much nitrogen and just spur leaf growth) and not pruning after late winter, because the vine flowers on new growth.

This article is a good summary of the issue:

I hope you have flowers soon!

Thank you for the advice. Should I start pruning it now in hopes it will bloom next year?  I’ve attached pictures of it right now in July.

Wow, that is vigorous! You should prune in late winter or very early spring. If you pruned now you’d cut off any flowers that might be coming later this summer.
