Trumpet Vine
*
Fellow Gardeners, I have a Trumpet Vine that never blooms. It is located in full sun, climbing up a telephone pole in my backyard. Been told to prune in spring, since it blooms on new wood. Have done this the last 4 years and still nothing, my Hummers are totally bumming out. I've also read that too much fertilizer can result in few blooms. Well, our lawn service always hits that area no matter what, so how can I prevent this? Am I correct in pruning each spring? To prune or not to prune, that is the question. Thanks...

Ha! Our work at developing a non-blooming trumpet vine with no redeeming qualities has finally paid off!
It'll bloom. Don't prune it, just let it go till it starts to bloom. Then prune it no later than mid summer. I think they bloom on old buds, but I don't know that for sure. In any event, if it's concentrating on replacing alot of green stuff, it won't go to the effort of producing flowers. Like wisteria, it can take years to come into bloom. Whatever you do, don't root prune it like you would a wisteria. You'll have it everywhere.

Speaking of root-pruning wisteria, I have one that is 4 years old and yet to bloom. I wanted to try the root prune/superphosphate trick, but can I do that in very early spring, or is it a fall only deal?

Nope, go ahead and do it now. It won't make it bloom this spring, but it might put on a few blooms during the summer. And if not, it'll probably cause it to set bloom buds for the following spring. If you wait till fall, you won't get blooms the next spring. You need a growing season between when you root prune and when it sets bloom buds.

Had the same problem with two trumpet vines - you must get the lawn service to avoid fertilizing the area - otherwise it concentrates on putting out leaves, not blossoms. I pull out the sucker vines throughout the season, and have never had a problem, and cut it back in the fall, after it has lost its leaves. After four years of nothing, I made sure to keep the fertilizer away, and now they both bloom like crazy (one in light shade, one in full sun). Living in the northeast, I find these vines attrack Baltimore Oriels (sp?) because the birds are seeking out the hundreds of ants that patrol the blooms. Good luck.

Hi,
I had a trumpet vine that did not bloom for the first 4 years I had it, I almost pulled it out, but last year it finally bloomed. When I bought it the Garden Center guy told me it would not bloom the first few years, so that was the reason I was so patient with it..The only thing I did differently last year was to add fertilizer about once a week when watering.
Hope this helps a bit.
