When do Hummingbird vines bloom?

I have a 3 yr old hummingbird vine grown in a pot from seed and have never gotten blooms on it.





I always feed my plants with some kind of fertilizer whether osmicote 3-month feed, rose food, or sam's choice plain old plant food.





The thing grows like mad - I keep it trimmed weekly because I'm wanting to bonsai it eventually (need the thick trunk).





Does it bloom on new wood or old wood?


Or is it like a dogwood or wisteria and not bloom for its first few years?

When do Hummingbird vines bloom?
Hummingbird vine (Campsis radicans) blooms in summer-fall on new wood. So, that is perhaps the problem - you may be pruning all the new growth off and ending up without any flowers.





This plant is quite a monster - so keep on top of it so it doesn't get out of hand. You can do a hard prune in late spring to get the dead wood out of it and then let it go if you want blooms.

Good luck!
