Why are there no flowers on my trumpet vine?

Question

I planted a trumpet vine this spring in a container. The vine is growing very well, but has not has a flower all season. Any ideas why? What can I do?

Answer 1

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.
