This is best done in early spring or fall—but not before the third year. Unearth, or lift, the plants, allowing a good few inches from the base/cluster of stems. Shake off the soil and you should see a cluster of “knobs” at (what would be) ground level, with roots coming out of the bottom and stems coming out the top of them. Each knob is a plant. Separate them with a clean, sharp knife and replant each knob.
