wisteria vine and it has yet to bloom
Three summers ago I bought a wisteria vine and it has yet to bloom any flowers. The vine has grown over my trellis with lots of leaves but no flowers. Very disappointed.

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.
