Remedy Ultra Herbicide will kill or injure all woody plants that are contacted with the spray including rose of sharon. It grows from the root and should not be treated in the heat of the summer as the leaves turn hard and become impervious. You can spray Remedy Herbicide on when they put on nice leaves for eradication. Please let us know if you need anything else.
