Zoysia is a warm-season grass that is native to Asia, according to the University of Missouri's website. Zoysia grass grows best in full sun, with six to eight hours of sunlight a day. Zoysia grass also creates dense lawns that can be difficult to mow. While Zoysia grass is most often planted by sodding, plugging or spriging, you can plant Zoysia grass from seed, although the quality of the lawn might be questionable, according to the University of Kansas.
Test your soil for nutrient requirements and pH. Your university's horticulture department should provide the test results if you submit it to them.
Remove all the large rocks and weeds from the area you want to plant the Zoysia grass seed. Till the soil to a depth of 4 to 6 inches. Add 4 to 5 inches of compost to improve your soil's drainage and work it into the soil to a depth of 6 inches, if needed. Add lawn fertilizer that meets your soil's needs and work it into the soil to a depth of 4 to 5 inches.
Sprinkle the Zoysia grass seed on the soil at the rate of about 50 seeds per square foot. Cover the seed with ¼ to ½ inch of soil and roll over it with the roller.
Water the Zoysia grass seed until the soil is moist. Keep the soil moist but not soaking until the grass sprouts.
Cover the freshly planted Zoysia grass seed with thatch about ¼ inch deep to hold in moisture and protect the seeds.
