wisteria not blooming well
We have a fairly old wisteria vine on a pergola that has always done well...usually around Mother's Day it is covered with blossoms, then they drop and the leaves appear. This year it didn't bloom nearly as much and the leaves came out simultaneously...I didn't prune it beyond the haircut every now and then last summer when it was getting a little too enthusiastic. Has anyone else had this problem? Is it because of our weird hot/cold winter? (I have noticed some other wisterias locally doing fine.) thanks!
