Dividing Plants

Propagation by division involves digging up a plant and dividing the plant into two or more pieces by splitting its crown and root ball. Because this method is high-impact, its use should be limited to plants already established in your own yard or to salvaged plants (see next section).

Plants that can be divided usually have at least two unattached stems, such as the plants listed to the right. Dividing should be done when the plants are dormant (late fall through winter). Dig the entire plant up, then carefully divide the crown and root ball into two equal parts with your hands or a sharp spade or knife (if the root ball is particularly large, you may be able to divide it into more parts). Replant each division.
