Maintenance
Emerald 2Water your new lawn to keep it moist for a period of 2 weeks or until sod is rooted.
Mow as soon as your new lawn is rooted - at the recommended height(see table below).
Fertilize your new lawn once rooted.

Once your new lawn is rooted follow the chart below.

Mow when grass is this tall: 2" 5cm
Set cutting height of mower to: 1.5" 3.7cm

Mow with sharp mower blades.

Water to supplement rainfall shortages only. Avoid fixed timer irrigations settings. Zoysia best performs when it receives approximately 1 inch of water per week. If one or more inches of rainfall occur in a week,additional irrigation is not necessary. Do not water by over watering. 

Season Fertilizer Weed Control
Early Spring Weed and Feed Pre-Emerge
Late Spring 20lbs 16-4-8 + Iron As needed
Early Summer 20lbs 16-4-8 + Iron As-needed
Late Summer 20lbs 16-4-8 + Iron As-needed
Fall 30lbs 5-10-15 + Iron Pre-emerge

More Info:

Emerald Zoysia is a cultivar of Zoysia grass with a thin bladed leaf that forms a very lush lawn. It shares the drought and shade resistance of the other varieties.

This grass has a fine, soft texture and can be left unmowed as it only grows to a height of 6–12 inches (15–30 cm). When left unmowed, it forms a humpy convoluted surface which is sometimes used in oriental landscapes.

Emerald Zoysia is adapted to zones 7-11 and does well in warm, humid environments. It is an excellent grass for the southern and southeastern states. Once established it requires less water than St. Augustine but slightly more than Bermuda. It is drought tolerant due to its deep root structure. Browning may occur in triple digit heat, but adequate hydration can restore its vibrant green color in a matter of minutes. The grass is moderately shade tolerant, coming close to the shade tolerance of St. Augustine. However, it does not do well in full shade as compared to Rye and Fescue. An average of at least 3–4 hours of full sun per day is a good measure for healthy growth.[6] Flooding is tolerated, but constant saturation will eventually weaken the grass. This zoysia has a moderate cold tolerance and can be damaged by hard freezes and is not hardy in transition zones. Emerald Zoysia is a very slow growing lawn grass. Zoysia grasses are generally slower growing than Bermuda and St. Augustine, with Emerald Zoysia being one of the slowest growing Zoysia grasses. The grass exhibits a dense creeping growth, rather than an aggressive upward, or sprawling growth. The blade density is much higher than other grasses, giving a very dense, carpet-like, or "hedgehog" appearance.
