Monterey Florel Brand Growth Regulator does not list juniper on the label. The product label states that it has not been tested on all varieties of trees or shrubs which may have undesirable fruit. If it is necessary to treat plant species not listed above, treat only a small portion of the plant to determine the effectiveness of the product and to evaluate plant injury.
