Zoysia grass is one of the thickest and most lush kinds of lawn grasses available. Gardeners usually pre-treat zoysia seeds for quicker and higher rate of successful germination. A bare lawn is the best land to grow zoysia and should not be intermixed with other seeds or planted in lawns with existing grasses.
Wait until the soil temperatures have reach about 70 degrees Fahrenheit and temperatures during the day always reaches at least 75 degrees Fahrenheit. Do not wait too long after this point as your zoysia grass needs time to become established before winter arrives.
Spread,or broadcast he zoysia seeds. Use your hands or a seeding tool, such a hand held seeder or push seeder. Use about 1 to 2 pounds of seeds for every 1000 square feet.
Use a garden rake or roller to rake or roll over the area to cover the seeds lightly with soil.
Cover the area lightly with straw. The seeds need some sunlight in order to germinate, but this will help the soil retain moisture which is also essential to germination.
Ideally, water the seeds about a ½ to 1 inch of water 3 to 4 times a day during the first two to three weeks. The seeds should be consistently moist, but not sitting in pools of water. After germination, but still the first season, you can slow up on the amount of watering (once a day) and water a bit deeper (1 to 2 inches), especially when rainfall is scarce.
