I had clematis in these barrels and continually had to spray for powdery mildew. Finally I moved the clems to the ground (they needed more root space anyway). I would like to re-use these barrels and the dirt. What can I rinse through the dirt and what can I clean the inside of the barrels with that will kill the powdery mildew? |
