My rose of Sharon shrubs have many buds that did not bloom. I live in Toronto so winter is an issue for our shrubs. Do I remove the buds that do not bloom or do I keep them on the shrub through the winter for next year. My fear about keeping them on the shrub is ice forming and bending or breaking of the branches.
