Trumpet Vine trouble in LindsayON
I've had two yellow trumpet vines for 3 years now and each of the 3 summers they outdo themselves in greenery, growing to up to a healthy 20 feet but have never bloomed. I fertilized this spring and summer but still no blooms. I've been advised by a local nursery that they sometimes can take 3-5 years to become established. Is there any hope that these will ever bloom?
