If you cannot wait for six months only to know that they failed to germinate then the best way to propagate Dwarf mondo grass is through division of the plant. Dig out a large clump of Dwarf mondo grass from soil and cut it in to small sprigs either with hand or knife. Now, plant the sprigs in your desired location about six to eight inches apart. Take care and water the clumps well until they get established in the soil. This way surely propagates the Dwarf mondo grass and the new plants will be akin to the parent. For best results, cut the Dwarf mondo grass either early in the fall or early in the spring. This way of propagating the Dwarf mondo grass is not only easy but also cheap. A single clump can be separated in to 50 to 100 sprigs. You can get a clump from your neighboring yard or can even order the sprigs at a wholesale supplier.
For perfect growth, use weed free compost for up to 3 inches in the planting area. After the sprig gets established start using NPK fertilizer with 5-10-5 combination at least once in a month. It is recommended to use liquid fertilizer during the first six months. This will ensure that the sprigs grow and spread perfectly. Later you can continue to use fertilizer pellets once in a year after mowing. For those pellets to dissolve well in the soil water the grass after application of the fertilizer.
