Wisteria Vine That Does Not Flower
We moved into this house in MI about four years ago. A mature wisteria vine covers an arbor. It has never flowered. Is there any way to get this to flower?

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.
