How to Propagate Dwarf Mondo Grass


Mondo grass (Ophiopogon japonicus) thrives in areas near streams and ponds. Although it's not a true grass, mondo closely resembles common types of lawn turf. Some varieties of this evergreen groundcover produce small blossoms in shades of white and purple. Dwarf mondo grass grows to a mature height of just 3 to 4 inches tall. It reproduces by vegetative division. Propagate existing patches of this attractive groundcover to plant near flowerbeds and walkways.

Step 1

Plant this dwarf in a shady area of your landscape. Avoid low areas that frequently flood or retain water for long periods. Remove the weeds and existing plants from your planting area to make room for the grass. It does not compete well with invasive grasses and weeds. Dig out stems and roots, and remove rocks and twigs to provide a clean bed.

Step 2

Loosen the top 3 or 4 inches of soil with a shovel. Add some compost to soils that contain large amounts of heavy clay. Combine the compost with the existing soil, turning it over and under until it's well mixed. Smooth the surface of your planting site with a rake.

Step 3

Divide clumps of mondo grass to propagate and produce new plants. Dig out a small section of the grass. Gently separate the individual tufts of grass from the main clump. Pull the entire tuft, including leaves and root segments, from the attached tufts. Each tiny plant contains its own roots. Do not allow these roots to dry before planting them in your prepared site.

Step 4

Transplant the separated plants into your soil by poking small holes with your finger into the loose soil. Make these holes between 2 and 4 inches apart and as deep as the roots of your small plants. Gently insert one plant into each hole by placing the delicate roots into the space made by your finger. Firm the soil around the roots. Do not plant these too deeply. Cover just the root portions with soil, allowing the green portions to remain above the surface. Water your transplants to moisten the soil. Keep the soil near the roots slightly moist at all times to promote healthy, strong plants.
