Coneflowers should be divided every four or five years, provided that they are healthy enough to tolerate division, and that they are indeed in need of it. To divide a coneflower plant, gently lift the plant out of the ground with a shovel and remove any excess dirt. Untangle any intertwined roots, and depending on the size of the plant and how overgrown it is, you may be able to pull it apart at the base with your hands, or you may need to use a knife or pruning shears to cut apart the base. Leave several stems (rosettes) on each division and lightly trim back the longer roots if they seem excessive. That’s really all there is to it! Dividing can be done in the spring or early fall.
