Our Hyacinth bean vine is lush; however it will not bloom. It was planted at the proper time and has been well cared for. What is the problem?

There are several possibilities. First, hyacinth bean like other beans tends to produce lots of vigorous vine growth at the expense of fruiting when it receives too much nitrogen. Beans produce their own nitrogen in nodules on the roots, and may only need a bit to get them started early in their life. Another consideration is that hyacinth beans tend to not flower much at all in summer, but rather really kick in when fall arrives. Finally, if the plant is not in full sunlight, this could be contributing to a lack of blooms.

My vine has no flowers at all and it's September. What can I do to reduce nitrogen in the soil? That seems to be the only thing it could be.
