Wisteria

Question

I have had my wisteria for over 4 yrs and it has never had any blooms. What do I need to do to get it to bloom?

Answer 1

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.
