Trumpet Vine

Anonymous added on November 1, 2014 | Answered

I have a trumpet vine that I keep pruned to the top of a trellis. It has great foliage but after 2 years it has never bloomed. Heard conflicting theories on why it hasn't, from it might not flower till after 3 years. Don't fertilize it, do fertilize it, etc. If it doesn't flower, I'm going to replace it with something that will. Thanks if you have any suggestions.

I would guess that the nitrogen to phosphorus ratio is off. The soil may have an abundance of nitrogen, which would result in nice, healthy green growth but little to no blooms. Without the right amount of phosphorus, it will not bloom well. Bone meal is a great way to add phosphorus.
