Non Flowering Wisteria Plant
I have a wisteria plant that is now 12 yrs old and well established but has never flowered. Is there something I can give it or do to encourage flowering, as this is why I bought it in the first place. It seems such a shame to have to buy a new one to start all over again.

I would guess that the nitrogen to phosphorus ratio is off. Even if you fertilize, without the right amount of phosphorus, it can't bloom well. Bone meal is a great way to add phosphorus. This article will also help:
