How do you split monkey grass?

To split monkey grass (Liriope), wait until early spring or fall when the plant is actively growing. Carefully dig up the clump with a spade or garden fork, ensuring you get as much of the root system as possible. Use a sharp spade or knife to divide the clump into smaller sections, each with roots and foliage. Replant the divisions immediately in well-drained soil and water them thoroughly.
