I planted a Chinese wisteria at least 6 years ago at my DE beach house. It's not growing or blooming. It's on the south side of the back yard a few feet from a plane tree and adjacent to the septic tank. At least twice a year, the back yard is covered with salt water. A neighbor's wisteria has practically taken over an empty sandy lot (it's covered the ground, as well as wound around several trees) . What does that wisteria have that mine does not?

Is there anyway you can increase the light it gets, perhaps by thinning out the branches of the tree or by even transplanting it?
