Depending on the space availability, you can decide on the number of plants you require. Dwarf Mondo grass requires 3-4 inch spacing and the larger growing species need a spacing of 5-6 inches. If you use more plants, the area will get covered faster. You can separate the individual plants from the clump and they can be planted in the soil with the root covered completely in the soil.

Growing Conditions

All varieties of Mondo grass require moist and well-drained soil with slightly acidic pH for their optimal growth. The plant can withstand light frost. If you experience heavy frosts, it is necessary to grow them in the frost-free regions. The plant grows very well when planted in partly shaded areas rather than in the full sun. Loamy soil will encourage faster root growth and the plant gets established easily. It is better to add well-rotted compost to the soil before planting to ensure that the soil retains moisture. The Mondo grass can be propagated by the division of clumps during spring or by sowing the seeds in the garden during autumn. It will take two weeks to six months for the seeds to germinate. It is necessary to use freshly harvested seeds to improve the germination rate. Propagation by division is the easier and cheaper method of propagating this plant.
