Wisteria

Question

I have a large wisteria bush that is probably about 5 yrs old. It bushes and branches out, and I prune it back throughout the growing season, really pruning it after the first freeze. The problem is that it only gives a few blooms. I would like to see it bloom like the ones in the magazines. How do I get my wisteria to produce more flowers?

Answer 1

I would guess that the nitrogen to phosphorus ratio is off. Even if you fertilize, without the right amount of phosphorus, it will not bloom well. Bone meal is a great way to add phosphorus.
