I have a Rose of Sharon planted from a whip about 8 years ago. It has
been a steady producer of blossoms. I have been pruning it down to keep
it from covering
a bedroom window on the South side of the house. The tree looks healthy
except that none of the numerous buds ever opened this year. It
receives almost full sun and
is watered regularly. What would keep the flower buds from opening? We
live in
a north suburb of Chicago.
