Around here, everyone's chionanthus trees (aka Chinese fringe tree) are exploding with fluffy white flowers. Everyone's except mine, that is. Just a few flowers on the ends of just a couple of branches. This is its third flowering season for me--when I bought it, it was covered with white blooms. Last year was sparse as well, but I chalked it up to a freak windstorm in late November. Now I think there's something I should be doing, or something I should not be doing. The tree is otherwise healthy. Ideas?
