Zoysia is a warm-season grass that grows well in most of the southern United States in areas that receive ½ inch of rainfall weekly. Zoysia is notable for being slow-growing, resistant to wear and forming a dense turf that resists weeds. Zoysia is considered easier to care for than other warm-season grasses such as Bermuda because it requires less mowing and will not creep into flower beds.
Dig 1 qt. of soil from several areas of the lawn's surface, using a shovel. Mix this soil in a bucket and allow it to dry. Fill a sandwich bag with 1 cup of soil and test it with a soil test kit. This will provide a pH reading and allow you to apply the correct soil amendments.
Break up your lawn soil with a plow attached to a yard tractor to a depth of 12 inches. Remove any sticks, rocks or debris.
Smooth and regrade your lawn with a landscaping rake. Your lawn should gently slope away from your home to channel water away from the foundation.
Add a 4-inch layer of topsoil to the top of your lawn if the soil test recommends it.
Spread soil amendments over your lawn in a 4-inch layer. Common amendments for a lawn include organic substances such as peat moss and compost, as well as sulfur to lower the pH or lime to raise the pH.
Smooth out your soil with the landscaping rake.
Water your soil 24 hours before adding seed to the lawn. Apply water at a rate of 1 inch of water per 1 inch of soil.
Pour zoysia seed into a broadcast spreader and adjust the spreader to fling seed across your path as you push the spreader across your yard. Zoysia should be applied to a new yard at a rate of 1½ lbs. of seed per 1,000 square feet of yard. Divide the seed into several parts and push the spreader over the yard multiple times. Vary the path you walk each time.
Water the seed up to four times daily, using ¼ inch of water per 1 inch of soil each time. Continue this for two weeks while the seed germinates. Gradually reduce the rate of water until you use only 1 inch of water per 1 inch of soil every 10 days.
