Wisteria Blooms

This picture is from last year but yesterday afternoon I saw that my wisteria has buds. I have discovered that the more I cut it back the more it blooms. I was told that they had to be old before blooming. I'm not sure how old but this one is about seven years and it has bloomed since it was about three. In the spring of 2008 it bloomed heavily. I cut it back severely in the fall and a friend told me that was one of the reasons it bloomed so much. The blooms are large and beautiful-not at all skimpy.
