Use a sharp spade to cut around the plant and gently lift as much of the root ball out of the ground as possible. Smaller root balls can usually be cut into pieces using a sharp knife. Larger clumps can be sliced with a sharp spade or pried apart using two back-to-back garden forks. Remove excess soil from the root ball so you can see what you are working with and remove any rotted or damaged roots. Replant the new plants as soon as possible at the same depth the plant was growing at or slightly higher to allow for settling, and water the soil thoroughly. If you can’t replant the same day, pot up the divisions and keep well-watered until they are established.
