Zoysia grass is a warm season grass that has stiff stems and leaves. It does well in dry conditions, only needing irrigation occasionally. The turf is thick and vibrant from the middle of May to the middle of September. However, once fall frosts arrive, zoysia grass becomes dormant. It will stay brown until the spring warm up. Zoysia grass thrives in full sun but can also grow in moderate shade--with a thinner turf. Established zoysia grass can fight off weeds well. Fertilizing, mowing and watering will make your lawn look its best.
Plant zoysia grass in an area that gets full sun and a decent amount of rainfall. Both will result in better-than-average growth.
Fertilize zoysia grass in the spring and summer. Use about 15 lbs. of a complete fertilizer per 1,000 square feet of lawn. Fertilizing too much or too little can cause thatch build up and make the grass less resistant to disease and pests.
Add supplemental feedings during the growing season, if needed. Spread 2 to 3 lbs. of nitrogen to promote the greenest lawn possible. Space the applications out at least 50 days apart.
Mow zoysia grass when it reaches 2 1/2 to 3 inches high. Cut it to a height of 1 to 2 inches for best results. Zoysia has a stiff leaf blade texture which becomes tougher as the leaf grows longer. You may need to sharpen your blades to cut through the zoysia grass cleanly. Cut the lawn once or twice a week. If the zoysia grass is in the shade, let it remain a little bit taller--between 2 and 2 1/2 inches tall.
Water zoysia grass only when it looks like it needs it. The species resists drought well because of its extensive root system. One inch of water per week is enough for good growth. If the blades curl inward, water manually. Water in the early morning so the grass has time to dry. Watering in the evening will invite disease.
