Hi Donna, Dig the
plant out of the ground and place two garden forks or hand forks back to back and then lever their handles together. This pulls the
plant apart and untangles the roots. You will need to repeat this technique several times to end up with small divisions of the main clump. A golden rule is usually to throw away the center part of the main clump and
keep and replant the outer parts of the plant. The center of the clump is the older part and becomes woody. This works for all
plants with fibrous roots:Campanulas Artemisia, Asters, Bee Balm, Coneflower, Golden Rod, to name a few
