I planted a trumpet vine this spring and it is growing very well. However, there are no flowers on the vine. It is in full sun. What could be the problem?

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.
