I had planted my trumpet vine over 3 yrs ago and still have no flowers. It is growing rapidly and the greens look healthy. My soil is sandy and it gets full afternoon sun. Any tips for getting blooms next summer?

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.
